Technical Manual : 6521355 V1.8.0 07/2014

Installation Data

ELECTRICAL

CAUTION

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.

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 (if fitted), evaporator trace heating

and control circuits, FAILURE to do so could INVALIDATE WARRANTY.

Interlocks & Protection

Always electrically interlock the operation of the chiller with the pump controls for

safety reasons.

CAUTION

Do not rely solely on the BMS to protect the chiller against low flow conditions.

If a pump package is not selected as part of the unit, an evaporator pump interlock

MUST be directly wired to the chiller, to

Interconnecting Wiring diagram. Failure to comply will invalidate the chiller

warranty.
