Installation and operation
Earthing
Verify the total power supply requirements provided on the
compressor nameplate before connecting the compressor
to electrical lines. Connect the earthing line to the point
provided in the control panel box of the compressor.
Check the direction of rotation as per the arrow indication,
to check-start the compressor. Stop it immediately after
the check-start by pressing the emergency stop button.
Switch on the compressor after ensuring all the above
points and let it run at the rated speed.
In case of problems during the compressor operation,
check the warning fault code that appears in the controller
of the compressor. Refer to the Functional Description and
Operation sections of this manual to know more about the
fault.
If you hear any abnormal noise when operating the
compressor, switch it off immediately and contact the ELGi
service engineer.
Follow all above points when you need to reinstall the
compressor at a different location. If the compressor had
been in storage for an extended period before
commissioning, contact the ELGi service engineer.
