Device protection
Stop!
The regenerative power supply module contains components which can be
destroyed in case of contact by electrostatic discharge!
Prior to working on the controller, the personnel must be free of electrostatic
charges by touching an earthed metal surface.
Frequent mains switching can overload the internal starting current limitation. In
ƒ
case of cyclic mains switching the regenerative power supply module may only be
switched on once every three minutes.
Connect a mains filter before using the regenerative power supply module.
ƒ
The supply and feedback module is protected by external fuses.
ƒ
In case of condensation, do not connect the regenerative power supply module to
ƒ
the mains voltage before the visible moisture has evaporated.
Cover unused control inputs and outputs with plugs.

Operation of the controllers
No restrictions
Not permitted
The supply system must be able to absorb the recovered energy. Otherwise,
overvoltages may be generated in the supply system which destroy all loads
connected.
