Hardware Installation 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
7-4.
Figure 7-4 Fastening Cable Lugs
Remarks
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 cords 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 by using cable ties based on the following table.
