Cabling
The external cables to be connected involve DC power cable,
protection ground cable, audio input cable, audio output cable,
video cable, straight though cable, communication cable and
digital quantity collection cable. During the on-site installation,
the cable connectors should be welded according to lengths of
the actually used external cables.
Cabling Requirements
1. The laid cables must be protected with sheaths, such as PVC
pipe, PVC troughs, metal tubes, serpentine pipes or
winding tubes.
2. The AC cables and the DC cables must be laid separately,
but DC cables can be laid together with signal cables, video
cables and network cables.
3. If there is the antistatic floor in the room, the cables should
be laid under the floor. If there is a cabling rack in the room,
the cables may be wired along the cabling rack. If neither
of them is available, the cables should be laid along the
wall foot or top.
4. If all the cables are laid on the cabling rack in the room,
observe the existing layout principle of customer. If the
original cable of customer is not added with the PVC tube
or trough, the tube and trough can be ignored generally.
