Installation, Usage and Maintenance
This device requires professional installation and maintenance.
Product wiring should be done strictly as per input wiring mark.
The device must be reliable earthed to avoid any injuries, fire, explosions and equimpent damage.
Voltmeter must be used to check that the power sources are disconnected before installation.
Periodically make normal inspection
