SAGEM 3P@C
Note the following requirements when connecting the subscriber cables:
The cabling boards in the middle should be fully utilized and the binding should be neat and make preparations for later expansion.
The cabling should be on the right primarily to ease cable installation and future cable expansion.
Pay attention to the angle when inserting the cables into sockets. Do not bend the pins.
The cables should be bound in order and uniformly.
The sockets not plugged with any cable must be installed with claw locks to avoid loss.
Try to separate the power cables, working ground cables and protection ground cables from the subscriber cables.
The techniques for binding the subscriber cables are as follows:
The cables of the racks should be bound orderly, clearly and neatly. Bind the cable ties in a round shape, and route the cables from the cabling holes on the flank of the rack to the rear side of the rack before upward cabling or downward cabling. For a nice appearance, all the cables should be arranged to both sides along the beams of the frames and led out along the sides. The cable ties should be spaced evenly and bound properly. Excessive length of the tie heads should be cut off so that the cable tie heads all have the same length.
Cables from the cabinet to the distribution frame should be bound and then placed neatly and closely.
When supports and antistatic floorboards are installed for the equipment, it is recommended to lay the cables in the method of downward wiring for easy and nice layout. If no support is installed for the equipment, the cables should be laid by means of upward wiring. In this case, cabling racks should be provided above the cabinet. When upward wiring is adopted, cables should be laid through the cabling racks or cabling troughs on top of the rack.
The size, route,
The subscriber cables should be laid separately from the power supply cables.
The bending radius of cables should be no less than 40 mm to protect the wire core from being damaged, as shown in Figure
The insulation layer of the cable should not be damaged. The routing of cables should facilitate maintenance and future expansion.
Cables routed in the cabling racks should be bound and arranged neatly and closely. The cable ties should be spaced evenly and bound properly. If twines are used for binding, they should be waxed.
Cables laid in a wiring trough may be bound or not bound. But they should be laid out neatly without crossover and should not run beyond the trough. The cables should be tied when led in and led out of the trough or when converting to another direction.
The labels made by SAGEM sa are used to number both ends of a cable. They are placed 20 mm away from the plugs.
