6.0 ELECTRICAL CONNECTION
Install electrical wiring in accordance with the National Electric Code and / or local regulations. A fused disconnect
switch must be used in a separate circuit from the main power panel. The switch should be reasonably close to the
unit for convenience in servicing.
Field and elementary wiring diagrams associated with the units are shown in this manual. The electrical data is
shown in the wiring diagrams.
Note: Elementary wiring diagrams are subject to change without notice.
The unit is designed for single power source connection. No separate supply is required for the controls. The units
are supplied for use on 380-415V-3Ph-50Hz.
The control voltage for the control panel operation is 220-240V-1Ph-50Hz.
- Make sure that the unit is properly grounded by checking the tightness of earthing connection. Each system
contains factory mounted, wired, adjusted and tested controls which required to operate and protect the unit.
The control system includes compressor and fan overload protection, phase protection, high and low pressure
cutouts to guard against compressor damage due to high discharge pressure and refrigerant leakage.
IMPORTANT:
* The figures shown in the Table 7 are for information purpose only. They should be checked and selected to comply
with the local/national codes of regulations. This is also subject to the type of installation and conductors used.
* All wires must be firmly connected.
* All wires must not touch the refrigerant piping, compressor or any moving parts of the fan motor.
* Make sure no external pressure is applied to the terminal connectors and wires.
