Electrical connection

3.2.1 Power supply connections
The electrical connection of the condensing unit to the power supply must be made by qualified
technicians according to the valid electrical directives, for instance DIN EN 60204-1. Also the
voltage drop and temperatures on line must be considered for cable selection.
The [ CF ] EASY units are designed for a 380-420V / 3Ph / 50 Hz power supply for TFD and
220-240V / 1Ph / 50 Hz for PFJ. A voltage tolerance of ± 10% is acceptable.
The circuit breaker must be switched off before opening the front door.
WARNING
Electrical shock hazard! Serious personal injuries! There are unused
fast-on pins (C1 & D02) on the XCM25D which could be under voltage. They
are covered by insulated fast-on flags in the factory. Handle carefully when
removing insulating flags during service on site.
