WARNING

THE DEVICES MUST BE EARTHED.

Safe operation of the devices presupposes that qualified personnel install and commission it in
compliance with the instructions provided in these operating instructions.

In particular, the general and regional mounting and safety regulations for work on high voltage
systems (e.g. VDE) must be complied with as must the regulations concerning professional use of
tools and the use of personal protection equipment.

Dangerous voltages can be present at the motor connection terminals of the frequency inverter
even when the inverter is switched off. Always use insulated screwdrivers on these terminal fields.

Ensure that the input voltage source is not live before setting up or changing connections to the
unit.

Make sure that the inverter and motor are specified for the correct supply voltage.

Cable glands

Both the SK 200E connection unit and the bus module provide extensive facilities for the connection of all the
required cables. The cables may enter the housing via cable glands and be connected to the terminal bar.
However, appropriate round plug connections (e.g.: M12 round plug connectors in M16 cable glands) may be
fitted in order to provide a plug-in solution.
