3.2 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.
Copeland EazyCool ZX units are designed for a 380-420V / 3Ph / 50 Hz power supply for TFD and
220-240V / 1Ph / 50 Hz power supply 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
&
DO2
) 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.
