Hardware Installation and Reference Guide
○
The power cables connecting moving parts such as door grounding wires should be reserved with some
access after being assembled to avoid suffering tension or stress. When a moving part reaches the
installation position, the remaining cable part should not touch heat sources, sharp corners, or sharp
edges. If heat sources cannot be avoided, high-temperature cables should be used.
○
When screw threads are used to fasten cable terminals, the bolt or screw must be tightly fastened, and
anti-loosening measures should be taken, as shown in
Figure 7-7 Fastening Cable Lugs

② Nut
○
Hard power cords should be fastened in the terminal connection area to prevent stress on terminal
connection and cable.
○ Do not use self-tapping screws to fasten terminals.
○ Power cables of the same type and in the same cabling direction should be bundled up into cable
bunches, with cables in cable bunches clean and straight.
○
Bundle up cables using cable ties based on the following table.
Cable Bunch Diameter
10 mm (0.39 in.)
10 mm to 30 mm (0.39 in. x 1.18 in.)
30 mm (1.18 in.)
○ No knot is allowed in cabling or bundling.
○ For wiring terminal blocks (such as circuit breakers) with cord end terminals, the metal part of the cord
end terminal should not be exposed outside the terminal block when assembled.
