Installation Data
ELECTRICAL
General 
As standard the equipment is designed for 400V, 3 phase, 3 wire 50Hz and a
separate permanent 230V, 1 phase, 50Hz supply, to all relevant IEE regulations,
British standards and IEC requirements

The control voltage to the interlocks is 24V, always size the low voltage interlock and
protection cabling for a maximum voltage drop of 2V

Avoid large voltage drops on cable runs, particularly low voltage wiring
CAUTION A fused and isolated electrical supply of the appropriate phase, frequency and
voltage should be installed.
Wires should be capable of carrying the maximum load current under non-fault
conditions at the stipulated voltage.
A separately fused, locally isolated, permanent single phase and neutral supply
MUST BE FITTED for the compressor oil heater, evaporator trace heating and
control circuits, FAILURE to do so will INVALIDATE WARRANTY.
CAUTION ALL work MUST be carried out by technically trained competent personnel.
