Installation- Install foundation please refer to the following pictures, the base channel highlights on 1-3mm, in 1 meter range the unevenness should not be more than 1.5mm, in the full length range no more than 5mm.
- Place the switch hinge on the base in order, adjust the install position, then fix it with M12 bolt or spot welding method, tight it between cabinet and cabinet with M8 bolt.
- Open the rear cover plate and install the main busbar and primary power supply, pay attention to clean the terminal contact surface and paint neutral Vaseline on it, after installing seal the cable hole.
- Connect the grounding busbar between cabinet and cabinet, make it into one along the direction of switch cabinet, check whether the work-grounding and protect-grounding are missing, and whether the grounding circuit is connected, work-grounding resistance should not be more than 1000μΩ, protect-grounding resistance should not be more than 4Ω.
- Install the secondary cable, introduce the cable from the bottom of the cabinet in the front, and let them enter along the side wall to the low voltage room, tap them on the terminal blocks; or enter them from the secondary small busbar on the cabinet top into the low voltage room, after installing seal the cable hole.
- Clean up dust and impurities in the cabinet.
