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.
