Chapter 10. Installation and Wiring
Use a lightning surge protector to prevent damage from lightning strikes.
(1) Separate E1, the ground connection for lightning surge protector, and E2, the ground connection for XGT Panel.
(2) Set lightning surge protector to below the allowable surge voltage to provide protection if the voltage increases to
its maximum.
Use an insulation shielding transformer or noise filter when the electromagnetic interference occurs. Keep the stripped ends of
the terminated cables twisted and as short as possible. When running the wiring avoid running the cables for the insulation
shielding transformer or noise filter pass through the cable duct.
When you use the magnetic lighting contactor (MC) for AC/DC, it is recommended to use a ferrite core close to the power
terminals as shown below:
