1. Connect a ground wire from terminal 7
or terminal board TB-6 to a good ground
point on the machine frame or in the control
panel. Tighten both connections.
2. Connect a wire from terminal 6 of TB-6
to the hot side of the AC input line power
buss. Tighten both connections.
3. Connect a wire from terminal 5 of TB-6
to the neutral side of the AC input power
buss. Tighten both connections.
4. Set the AC input power selector switch
SW-1 for the proper AC input level.
Refer to Figure 7, Page 10 for location of
switch SW1, which is also diagrammed
below.
Clutch-Brake Wiring
Refer to Figure 2 for terminal strip connections.
Note: Normally, the brake magnet should be
connected to Channel 1 output and the
clutch field or magnet connected to Channel 2
output for proper functioning of the various
input control circuits. Other connections are
possible.
1. Connect the clutch field or magnet wires to
terminals 3(+) and 4(-) of TB-6. Wiring to the
clutch field or magnet may be either by
screw terminal or lead wires depending on
the model of the Warner Electric clutch.
Tighten the control terminal connections
and insure that the clutch field or magnet
connections are securely fastened.
2. Connect the brake magnet wires to
terminals 1(+) and 2(-) of TB-6. Wiring to the
brake field or magnet may be either by
screw terminals or lead wires depending on
the Warner Electric model. Tighten the con-
trol terminal connections and insure that the
brake magnet connections are properly
fastened and secured.
Note: If shielded wire is used for wiring the clutch
field or magnet and brake magnet, connect
the shield at the control end to Terminal 7 of
TB-6. Do not connect the shield at the magnet
end.
Insure that the shield lead at the
control end does not contact any of the other
terminal connections as shorting and control
damage may result.
Switching Inputs
Warner Electric’s CBC-750 Series Controls have been
designed to provide the user with numerous switch-
ing and signal input configurations. figures 4a - 4f,
starting below, describe them. Terminal blocks TB-1,
TB-2 and TB-3 provide for input connection depend-
ing on the type of device being used for switching
input. Select the proper diagram depending on your
input and wire according to the steps listed.
Note: Only two of the three terminals designated
for each input function are used, regardless of
the input switching.
All inputs shown are connected to the Channel 2
Input. The other input connections are identical to
those of Channel 2 Input. The (X) designation noted
below refers to any one of terminals 1-7 of the
appropriate terminal strip, depending on the func-
tion being used. See Figure 7, Page 10 to determine
the terminals to be used, which depend on function
and setup.
