version is via a IEC320-C14 connector with cable
strain relief, situated on the bottom of the cooling module.
A suitable connecting cable (IEC320-C13 Schuko) is provided with the module.
All cooling modules must be protected by an external pre-fuse of
max. 10 A.

Under certain circumstances during commissioning, completion, maintenance
and service it is necessary to open the enclosure.
Some exposed parts may be under live voltage. These works must therefore
only be carried out by specially trained technical personnel.
Always disconnect the supply voltage before opening the module!
