Adapting the unit to the mains voltage

NOTE
Only cooling units with a rated voltage of 400 / 460 V, 3~ can be optionally connected to another mains voltage.
•
Cooling units with the rated voltage 230 / 115 V, 1~ have no transformer options. No adjustment of the upstream fuse
is therefore required.

Potential equalization provided by customer
If the device is to be integrated into the customer's existing potential equalization for EMC reasons, a conductor can be
connected at the connecting point of the function potential equalization.
The connecting point is labeled with the necessary circuit symbol.
