6.0 ELECTRICAL CONNECTION
Before performing any service/maintenance work on the unit, ensure that the
power supply is switched off. Failure to do so may result in serious injury or
death.
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.
The unit with DOL starter control specification 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 and the control voltage for the
control panel operation is 220-240V-1Ph-50Hz.
The unit must not be restarted within 3 minutes after shutting down.
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.
Separate power cables as much as possible from the probe and
digital input cables to avoid possible electromagnetic disturbance.
Never run power cables and signal cables in the same conduits.
* 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.
* Use round crimp-style terminal for connecting earth wire to the grounding
screw inside the control box. Connect the power supply wires by matching to
the indication on terminal block. (Refer to the wiring diagram on the unit).
* Use the correct screwdriver for terminal screws tightening. Unsuitable screwdrivers can damage the screw head.
* Over tightening can damage the terminal screws.
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.
