Cable Connections
The deliveries include a bag with four clamps, screws and copper tape
(frame size R4 also an assembly plate). Clamp the control and encoder
cables as explained below. If more than four cables are needed,
connect the twisted screen (earthing wires) of the additional cables as
short as possible to the earthing rail next to the NIOC(P) board.
Clamping is very important with the encoder cable but less so with
relay and other digital signal cables.
1. Strip the cable according to figure below.
2. Frame size R4 only: fasten the assembly plate with screws to the
frame.
3. Connect the conductors to the appropriate terminals on the NIOC/
NIOCP board.
4. Ensure 360 degrees earthing by coiling copper tape onto the
stripped part of the cable underneath the clamp.
5. Fasten the clamps to the frame with screws.
6. Twist the screen (earthing wires) of the outer shield and connect it
through the shortest possible route (max. 2 cm) to the nearest
earthing terminal. With double shielded cables, connect each
conductor shield (twisted earthing wires) separately to the nearest
earthing terminal. Conductor shields of other than encoder cables
can be twisted together.
