Overview
ENG_495603.XML
To comply with high requirements regarding installation and ambient conditions, SINAMICS S120 Cabinet Modules are also available in a liquid-cooled version.
The power loss of the units is transferred to the cooling liquid and dissipated, without noticeably increasing the temperature of the surrounding environment. As a consequence it is possible to save the expense of controlling the climate of the electrical room.
The system consists of liquid-cooled Basic Line Connection Modules, Active Line Connection Modules, Motor Modules, an Auxiliary Power Supply Module, and a suitably selected cooling unit (Heat Exchanger Module).
Basic Line Connection Modules
Basic Line Connection Modules comprise a Line Connection Module and a liquid-cooled Basic Line Module. Basic Line Connection Modules are only suitable for infeed operation, i.e. they are not capable of feeding regenerative energy back into the supply system.
If regenerative energy is produced, e.g. when the drives brake, it must be converted into heat in external braking resistors using a supplementary Motor Module, which is used as Braking Module.
When a Basic Line Connection Module is used as the infeed, a line reactor appropriate for the supply conditions must be installed. If the infeed is realized via a transformer with an appropriate rating in 6-pulse operation with a Basic Line Connection Module or in 12-pulse operation with two Basic Line Connection Modules, the line reactor is optional and can be omitted.
If two or more Basic Line Connection Modules are operated in parallel on a common supply system in order to increase power, then line reactors must also be used.

Basic Line Connection Module ≤ 800 A
G_D213_XX_00106
Basic Line Connection Module > 800 A
Active Line Connection Modules
Active Line Connection Modules comprise a Line Connection Module, a liquid-cooled Active Interface Module and a liquid-cooled Active Line Module. Active Line Connection Modules can supply energy to the DC link and return regenerative energy to the line supply (energy recovery). The use of an additional Motor Module as a Braking Module is only required if the drives need to be decelerated in a controlled manner after a power failure (i.e. when energy cannot be fed back into the line supply).
In contrast to Basic Line Connection Modules, Active Line Connection Modules generate a regulated DC voltage which remains constant irrespective of fluctuations in the line voltage. However, in this case, the line voltage must remain within the permissible tolerance range. Active Line Connection Modules draw a virtually sinusoidal current from the supply system. Almost no harmonics occur. The total harmonic distortion factors of the current THD(I) and voltage THD(U) are typically in the range of approx. 3 % for rated current. THD(I) is calculated according to IEEE 519 (2014) and THD(U) according to IEC 61000-2-4 (2002). The stringent limit values of IEEE 519 (2014) are typically complied with.
Active Line Connection Modules always contain an Active Interface Module, which in addition to a Clean Power Filter, also includes the necessary pre-charging circuit for the Active Line Module.

Active Line Connection Modules compact
Active Line Connection Modules compact comprise a liquid-cooled Active Interface Module and a liquid-cooled Active Line Module. They can supply motoring energy to the DC link and return regenerative energy to the line supply. The line-side infeed via main switch with fuse switch disconnector or circuit breaker must be done on the plant side.
In contrast to Basic Line Connection Modules, Active Line Connection Modules compact generate a regulated DC voltage which remains constant irrespective of fluctuations in the line voltage. However, in this case, the line voltage must remain within the permissible tolerance range. Active Line Connection Modules compact draw a virtually sinusoidal current from the supply system. Almost no harmonics occur. The total harmonic distortion factors of the current THD(I) and voltage THD(U) are typically in the range of approx. 3 % for rated current. THD(I) is calculated according to IEEE 519 (2014) and THD(U) according to IEC 61000-2-4 (2002). The stringent limit values of IEEE 519 (2014) are typically complied with.
The line‑side infeed via main circuit breaker with fuse switch disconnector or circuit breaker must be carried out on the plant side.

Motor Modules
Each Cabinet Module is fitted with one SINAMICS S120 Motor Module in chassis format and covers the power range from 90 kW to 1500 kW (380 V to 480 V or 500 V to 690 V). The power rating can be extended up to approx. 5700 kW by connection in parallel.
The Motor Modules can also be used as Braking Modules (braking chopper) if a 3-phase braking resistor is connected instead of a motor.
Further information can be found in the SINAMICS Low Voltage Engineering Manual.

Auxiliary Power Supply Modules
Auxiliary Power Supply Modules supply power to the auxiliary power supply system of the SINAMICS S120 Cabinet Modules. The heat exchangers, which are installed in the SINAMICS S120 Cabinet Modules with degree of protection IP55, are one of the connections to the auxiliary power supply system. In addition, the auxiliary power supply system supplies the electronic modules with an external 24 V DC voltage. This is required when the DC link is not charged, for instance, in order to maintain PROFIBUS or PROFINET communication. The installation is analogous to the air-cooled Auxiliary Power Supply Modules with an additional water pipe system. The Auxiliary Power Supply Modules provide an expansion to the option K76 (auxiliary voltage generating unit) if higher power ratings are required.
Heat Exchanger Modules
Heat Exchanger Modules are used to dissipate the power loss from the converter. They comprise a deionized water circuit on the converter side and a raw water circuit on the plant side.
The hot deionized water in the circuit on the converter side passes through a low-maintenance circulating pump(s) into the water/water plate-type heat exchanger. This is made of stainless steel and connected to the raw water circuit on the plant side. The deionized water is cooled there by the raw water of the outer circuit and flows back into the drive.

Recommended service
The manufacturer of the antifreeze/inhibitor should analyze the coolant at least once per annum. The concentration and boundary conditions of the antifreeze/inhibitor should be checked. It may be necessary to correct the concentration on the plant side.
Protection against condensation
With liquid-cooled units, warm air can condense on the cold surfaces of heat sinks, pipes and hoses. This condensation depends on the air humidity and the temperature difference between the ambient air and the coolant.
The water which is produced as a result of condensation can cause corrosion as well as electrical damage such as creepage shorts and flashovers. As the SINAMICS units cannot prevent condensation if it is caused by the prevailing climatic conditions, any potential risk of condensation must be prevented by appropriate engineering or by precautionary measures implemented by the customer. These measures include the following:
- a fixed coolant temperature that has been adjusted to the expected air humidity or ambient temperature ensures that critical differences between the coolant and ambient air temperatures do not develop or
- temperature regulation of the coolant as a function of the ambient air temperature
The temperature at which water vapor contained in the air condenses into water is known as the dew point. In order to reliably prevent condensation, the coolant temperature must always be higher than the dew point.
The table below specifies the dew point as a function of room temperature T and relative air humidity Φ for an atmospheric pressure of 100 kPa (1 bar). This corresponds to an installation altitude of 0 to approximately 500 m above sea level. Since the dew point drops as the air pressure decreases, the dew point values at higher installation altitudes are lower than the specified table values. It is therefore the safest approach to engineer the coolant temperature according to the table values for an installation altitude of zero.

Liquid-cooled SINAMICS S120 Cabinet Modules are rated for an ambient temperature of 45 °C and installation altitudes up to 2000 m above sea level and a plant-side raw water temperature of 38 °C (<IP55) or 33 °C (IP55). At ambient temperatures > 45 °C and a plant-side raw water temperature > 38 °C (<IP55) or 33 °C (IP55), the output current must be reduced. Ambient temperatures above 50 °C are not permissible. At installation altitudes > 2000 m above sea level, it must be taken into account that the air pressure, and therefore air density, decreases as the height increases. As a consequence, the cooling efficiency and the insulation capacity of the air also decrease.
At installation altitudes above 2000 m, the line voltage must not exceed certain limits in order to be able to isolate the surge voltages according to IEC 61800‑5‑1 for overvoltage category III. If the line voltage is above this limit at installation altitudes > 2000 m, measures must be taken to reduce the transient overvoltages of Category III to values of Category II, e. g. supply of the devices via an isolating transformer.
For additional information, please refer to the SINAMICS Low Voltage Engineering Manual.
The intake temperatures in the plant/system side raw water circuit must always be at least 7 K below the intake temperatures in the converter-side deionized water circuit. This ensures that the cooling power of the Heat Exchanger Module of the deionized water circuit, specified in the technical data, can be dissipated to the raw water circuit.
In order to prevent condensation, the inlet temperature of the liquid coolant should be kept above the ambient temperature depending on the relative air humidity.
For additional information, please refer to the SINAMICS Low Voltage Engineering Manual.

Current derating as a function of the pulse frequency
To reduce motor noise or to increase output frequency, the pulse frequency can be increased relative to the factory setting (1.25 kHz or 2 kHz). When the pulse frequency is increased, the derating factor of the output current must be taken into account. This derating factor must be applied to the currents specified in the technical data.
For additional information, please refer to the SINAMICS Low Voltage Engineering Manual.
The following table lists the rated output currents of the Motor Modules with pulse frequency set at the factory as well as the current derating factors (permissible output currents referred to the rated output current) for higher pulse frequencies.

1) As factory setting, the following devices have a current controller clock cycle of 250 µs and a pulse frequency of 2 kHz: - 510 ... 720 V DC: ≤ 250 kW / 490 A, 6SL3725-1TE41-4AS5
2) As factory setting, the following devices have a current controller clock cycle of 400 µs and a pulse frequency of 1.25 kHz: - 510 ... 720 V DC: ≥ 315 kW / 605 A, except 6SL3725-1TE41-4AS5, - 675 ... 1035 V DC: All power ratings
3) With the "High output frequencies" license, which can be ordered as option J01 on the CompactFlash card for SINAMICS S120, the maximum output frequency is increased up to 650 Hz. For more information, see https://support.industry.siemens.com/cs/document/104020669
Overload capability
SINAMICS S120 Cabinet Modules have an overload reserve, e.g. to handle breakaway torques. If larger surge loads occur, this must be taken into account in the configuration. For drives with overload requirements, the appropriate base load current must, therefore, be used as a basis for the required load.
Permissible overload assumes that the converter is operated at its base-load current before and after the overload occurs, based on a duty cycle duration of 300 s.
Another precondition is that the Motor Modules are operated at their factory-set pulse frequency at output frequencies >10 Hz.
For temporary, periodic duty cycles with high variations of load within the duty cycle, the relevant sections of the SINAMICS Low Voltage Engineering Manual must be observed.
Motor Modules
Motor Modules can be configured on the basis of different base load currents.
The base-load current for a low overload IL is the basis for a duty cycle of 110 % for 60 s or 150 % for 10 s.
G_D213_XX_00035
Low overload
The base-load current IH for a high overload is based on a load cycle of 150 % for 60 s or 160 % for 10 s.
G_D213_XX_00036
High overload
The following applies to the Motor Module 6SL3725-1TG41-6.P3:
This Motor Module is particularly suited to high breakaway torques with applications such as drilling, mixers, centrifuges, and test bays. An additional duty cycle is required at output frequencies of 5 Hz to 10 Hz.
At output frequencies of 1 Hz to 5 Hz, the short-time current is 1900 A for 5 s.

High overload for Motor Module 6SL3725-1TG41-6.P3
Basic Line Connection Modules and Active Line Connection Modules
The base-load current for a high overload IH DC is the basis for a duty cycle of 150 % for 60 s or Imax DC for 5 s.
