Connecting the control cables to the terminals of the
external control unit
1. Route the cables to the control unit as shown below.
2. Ground the shields of the control cables at the clamp plate. Use torque 1.5 N·m (13 lbf·in).
The shields should be continuous as close to the terminals of the control unit as possible.
Only remove the outer jacket of the cable at the cable clamp so that the clamp presses
on the bare shield. The shield (especially in case of multiple shields) can also be
terminated with a lug and fastened with a screw at the clamp plate. Leave the other end
of the shield unconnected or ground it indirectly via a few nanofarads high-frequency
capacitor eg, 3.3 nF / 630 V. The shield can also be grounded directly at both ends if
they are in the same ground line with no significant voltage drop between the end points.
Tighten the screws to secure the connection.
3. Connect the conductors to the appropriate detachable terminals of the control unit. See
the default I/O diagram. Use shrink tubing or insulating tape to contain any strain strands.
Note:
Keep any signal wire pairs twisted as close to the terminals as possible. Twisting
the wire with its return wire reduces disturbances caused by inductive coupling. Keep
the shields continuous as close to the terminals of the control unit as possible.
Connecting a control panel
With control panel door mounting platform, connect the control panel as follows:
1. Connect an Ethernet cable to the RJ-45 connector of the control panel.
2. Connect the other end of the cable to the X13 connector of the control unit.
