Active Line Modules with external air cooling
4.3.1
The Motor Modules are connected to the power supply network via the Active Line Modules
with external air cooling which provide the Motor Modules with a constant DC link voltage.
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.
External air cooling uses the "through-hole" method. The power unit and its heat sink can be
inserted in a rectangular knockout at the rear of the control cabinet and mounted with a seal.
The heat sink and the fan (included in the scope of supply) project beyond the rear of the
control cabinet and the heat is dissipated outside the control cabinet or in a separate air
duct.
Danger to life if the fundamental safety instructions and remaining risks are not carefully
observed
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.
