CBC-450 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 neutral line of the AC power
source to Terminal 6 of Terminal Block TB-3.
Tighten screw securely.
2. Connect the hot side of the AC power
source as follows:
a. For 120 VAC, Terminal 5 of Terminal
Block TB-3. Tighten terminal securely.
b. For 220 VAC, Terminal 4 of Terminal
Block TB-3. Tighten terminal securely.
c. For 240 VAC, Terminal 3 of Terminal
Block TB-3. Tighten terminal securely.
d. For 380 VAC, Terminal 2 of Terminal
Block TB-3. Tighten terminal securely.
e. For 460 VAC, Terminal 1 of Terminal
Block TB-3. Tighten terminal securely.
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 magnet will
be engaged, 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 the
Channel 1 output Terminals 5 and 6 on
Terminal Block TB-2. Tighten terminals
securely.
2. Wire the second clutch to the Channel 2
output Terminals 7 and 8 on Terminal Block
TB-2. Tighten terminals securely.
3. This completes the wiring of the dual
clutch combination. 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 ener-
gized at power up and wire this brake to
the Channel 1 output Terminals 5 and 6 of
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 the dual brake
combination. 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.
