Active Line Modules Liquid Cooled

Active Line Modules generate a constant, regulated DC voltage in the DC link from the 3-

phase line supply voltage that supplies the connected Motor Modules with power.

This ensures that they are not influenced by line voltage fluctuations.

When the motors are in feedback mode, Active Line Modules supply power back to the line

supply. The regenerative feedback capability of the modules can be deactivated by

parameterization.

The DC link starts precharging as soon as the line voltage is applied and is independent of

its phase sequence direction. Load can be applied to the DC link after the module has been

enabled. An optional main contactor is required for disconnecting the voltage.

Active Line Modules can be directly connected to TN, IT and TT systems. The Line Modules

have an integrated overvoltage protection function.

Danger to life if the fundamental safety instructions and remaining risks are not carefully

If the fundamental safety instructions and remaining risks in Chapter 1 (Page 25) are not

observed, accidents involving severe injuries or death may occur.

• Adhere to the fundamental safety instructions.

• When assessing the risk, take into account residual risks.
