Power
Requiring device power, air-conditioning power and lighting

carefully check before running.
2.5 Grounding Requirement
It is important to keep this device grounded to ensure all of the modules
function correctly. Correctly grounding the device will also help prevent any
electrical interference, lightening. Etc. Also it helps reject minor interference that
may disrupt the devices ability to function smoothly. General rule of them, make
sure the device is grounded when installing anywhere.
Always use copper wire. When applied correctly the ground must be wrapped
well to ensure maximum conduction so it can reduce any high frequencies. The
copper ground wire should also be as short and thick as possible
Installer must make sure that the two ends of the ground are well conducted
and have appropriate anti-rust properties.
It is prohibited to use any other device as part of the grounding electric
circuit.
The area of the conduction between the ground wire and device’s frame
should be no less than 25
㎡
