To guarantee safe and reliable operation of the cooling unit, ensure the following general requirements:
•
It is prohibited to connect an upstream temperature control on the supply side.
•
Connect the fuse specified on the type plate upstream as a line protection, see section "Type plate", Page 17and
"Adapting the unit to the mains voltage", Page 39.
•
Always connect the cooling unit to the mains via a disconnecting device (switch/contactor).
–
The disconnecting device must have a contact opening of 3 mm. The disconnecting device is provided and fitted
by the customer.
•
Install an all-pole sine filter (phase-phase and phase-ground) when using a frequency converter.
