Caution
Only trained electricians are permitted to work on the electrical
system.
Note the supply voltage (on the nameplate). Connect L1 /L2 /L3, neutral and ground wires with the
appropriate cross section and fusing. Pass the cable into the switch panel through the PVC
screwed union provided and connect to terminal.
Main switch connection
The main switch must be connected at the customer with an approved cable. Strip the cable right
before the main switch only. Do not lay stripped cable in the cable trunking.
Attention: Supply voltage must be present even when the machine's main switch is turned off in
order to guarantee the function of the crankcase heating in the refrigeration unit.
Ground-fault circuit interrupter at the customer
We recommend that the customer install a ground-fault circuit interrupter
that is AC/DC sensitive. You must install an AC/DC-sensitive ground-fault
circuit interrupter on frequency-regulated machines.
