Electrical
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 2 volts.
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.
Ensure correct phase rotation.
A separately fused, locally isolated, permanent single phase and neutral supply is required for the
evaporator trace heating and control circuit.
CAUTION
●
Please refer to the electrical wiring diagrams provided for installation.
●
ALL work MUST be carried out by technically trained competent personnel.
● The equipment contains live electrical and moving parts, ISOLATE prior to maintenance or
repair work.
● The unit isolators DO NOT isolate the incoming mains supply, but isolate the individual
electrical circuits. Isolate REMOTELY the mains incoming supply prior to maintenance or
repair work.
●
Ensure electrical lock off procedures are conducted.
