Interconnecting Wiring
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.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 permanent single phase and neutral supply must be fitted for the evaporator
trace heating and control circuits and for the leak detection and ventilation systems to work in the
event of a leak being detected.
All work must be carried out by technically trained competent personnel.
Failure to do these actions will invalidate warranty.
Isolate remotely the mains incoming supply to the busbar chamber prior to maintenance or repair
work.
CAUTION
(1) Must be directly wired to the chiller to validate warranty.
IMPORTANT
This system has been designed to be connected to a TN type distribution system. For alternate
distribution type systems, contact Airedale.
