Electrical Installation
The electrical installation process includes the wiring of the indoor unit and condenser power
cables.
The following points discuss some aspects that are taken into consideration during the
electrical installation process:
•
The connection of all the power cables, control cables, and ground cables should be as
per the local and national electrical regulations for that location.
•
The electrical installation and maintenance must be performed by authorized
professional personnel.
•
View the unit nameplate for the full load current. The cable sizes must be determined
based on the compliance with the local wiring protocols.
•
Primary supply requirement: -380Vac (-10%`to +15%), 50 Hz, 3N.
•
In case of damage to the soft power cable using a Y-connection, it must be replaced by
professional service experts.
•
Prior to wiring, use a voltmeter to measure the power supply. While doing this, ensure
that the power supply has been switched off.
•
TN and TT type star connections to the power distribution systems are used. If any
other type of connection is required, please call the support number for Vertiv Co.

Use a breaking device in order to get disconnected from the power supply.
