2.3.3 Residual hazards - ECSxK capacitor module
Protection of persons
ƒ Before working on the capacitor module, check that no voltage is applied to the
Protection of devices
ƒ All pluggable terminals must only be connected or disconnected when no voltage is
ƒ The power terminals +UG, -UG and PE are not protected against polarity reversal.
ƒ Only when all devices of the interconnected power system are ready for operation,
Connecting and disconnecting the supply module cyclically to and from the mains can
overload and destroy the input current limitation of the capacitor module
ƒ if the relay or the 24 V supply are switched off.
ƒ if the capacitor module is not supplied via a supply module delivered by Lenze.
If the input current limitation is used, allow a break of at least 3 minutes between two
starting operations in the case of cyclic mains switching over a longer period of time!

power terminals
– because the power terminals +UG and -UG carry hazardous voltages for at least 3
minutes after mains disconnection at the supply module.
– because the power terminals +UG and -UG carry hazardous voltages when the
motor is stopped.

– Observe the polarity when wiring the power terminals!
