Wiring Installation
CBC-400 Clutch/Brake and Power Wiring
Make certain AC input power
is off before making any wiring connections.
Observe any and all lock out procedures so
established by any local or national codes.
Failure to do so could cause serious injury
(even death).
1. Connect the hot line of the AC power
source to terminal 1 of TB-2 and tighten
screw securely.
a. 120 VAC for CBC-400-90
b. 24-30 VAC for CBC-400-24
2. Connect the neutral line of the AC power
source to terminal 2 of TB-2 and tighten
screw securely.
a. 120 VAC neutral for CBC-400-90
b. 24-30 VAC neutral for CBC-400-24
3. Based on mode jumper selection under
initial installation, determine if clutch-brake
combination, two clutches, or two brakes
will be used. Proceed to that section for
appropriate wiring instructions.
4. Connections for alternate mode (single)
operation.
a. Clutch/Brake Combination
1. Connect brake to Channel 1 output,
Terminals 5 and 6 on Terminal Block
TB-2. Tighten terminals securely.
2. Connect clutch to Channel 2 output,
Terminals 7 and 8 on Terminal Block
TB-2. Tighten terminals securely.
3. This completes the wiring for the
clutch/brake combination. Proceed
to the switching input section for
connection of switching input
circuits.
NOTe: In alternate mode of operation (single),
the control powers up with Channel 1 “on” until
a switching input change occurs on the Channel
2 switching input. One or the other magnets will
be energized, both units cannot be turned off
simultaneously unless AC power is removed
from the control.
b. Dual Clutch Combination
1. Determine which clutch is to be engaged
at power-up and wire this clutch to
Channel 1 output Terminals 5 and 6 on
Terminal Block TB-2. Tighten terminals
securely.
2. Wire the second clutch to Channel 2
output Terminals 7 and 8 on Terminal
Block TB-2. Tighten terminals securely.
3. This completes the wiring of a dual clutch
arrangement. Proceed to the switching
input section for connection of switching
input circuits
NOTe: In this mode of operation, one clutch
or the other will be engaged. Both clutches
cannot be turned off simultaneously unless
AC power is removed from the control.
c. Dual Brake Combination
1. Determine which brake is to be energized
at power up and wire this brake to the
Channel 1 output Terminals 5 and 6 on
Terminal Block TB-2.Tighten terminals
securely.
2. Wire the second brake to the Channel 2
output, Terminals 7 and 8 on Terminal
Block TB-2. Tighten terminals securely.
3. This completes the wiring of a dual brake
arrangement. Proceed to the switching
input section for connection of switching
input circuits
NOTe: In this mode of operation, one brake or
the other will be engaged. Both brakes cannot
be turned off simultaneously unless AC power is
removed from the control.
