All the AC and DC cables, and communication cables must be put through metal pipes for protection. The metal pipe
should be connected to the PE bar reliably. Plastic coated metal hoses are recommended.
Position Of Cable Entry Holes
There are 16 cable entry holes at the bottom plate of each cabinet for cabling. The position is shown in Figure 2-19.
During connection, use an electrician knife to cut the cable bushing, and then lead the cables through the cable entry
hoses. After connection, use fire-proof mud to seal the cable entry holes.
