There are switching options that can be used with
the CBC-802 clutch/brake control. Determine which
switching option you will be using and wire the
switching inputs for that option.

q
1. Connect the normally open start switch
contacts to terminals 7 and 8 of the socket.
Tighten terminal 8 securely.
q
2. Connect the normally open stop switch
contacts to terminals 7 and 3 of the socket.
Tighten both terminals securely.
q
3. This completes the wiring of the CBC-802.
Double check all terminal wiring at this time.

or
When using option 2 for switching input, the
switch wiring must be such that in normal state the
contacts are closed at power-up to insure brake
output is energized. Switching can be either through
a maintained type switch or relay contacts as shown
above.
q
1. Connect a jumper wire from terminal 7 to
terminal 8 of the socket. Tighten terminal 8
securely.
q
2. Connect the normally closed switch or
normally closed relay contacts to terminal 7
and terminal 3 of the socket. Tighten both
terminals securely.
q
3. This completes the wiring of the CBC-802.
Double check all terminal wiring at this time.

When using solid state
switching, the emitter or output common of
the switching device cannot be grounded. If
the outputs are grounded, then either different
switching devices must be used or an input
isolation transformer on the AC input to the
CBC-802 must be used, or the CBC-802 will be
destroyed.
q
1. Connect the collector of the NPN output
transistor or switching device to terminal 3
of the socket for stop input. Tighten terminal
3 securely.
q
2. Connect the collector of the NPN output
transistor or switching device to terminal 8
of the socket for start input. Tighten terminal
8 securely.
q
3. Connect the emitter of the NPN output
transistors or switching device common
for both stop and start to terminal 7 of the
socket. Tighten terminal 7 securely.
q
4. This completes the wiring of the CBC-802.
