ENG
NOTE
Protective conductors in the mains connection cable are not regarded as potential equalization conductors.
Prerequisite
DANGER – Danger to life due to electric shock. Make sure that the unit is voltage-free.
• All general requirements for safe and reliable operation are fulfilled.
Procedure
1. Make the mains connection according to the circuit diagram, see chapter "Electrical circuit diagram – Standard-Controller
(SC)", Page 39.
2. Open the cage clamp terminal of the connecting plug with the flat screwdriver and connect the cables on the plug.
– Firmly insert the screwdriver into the cage clamp terminal. Never turn, this will damage the cage clamp terminal.

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.
