Warner Electric CBC-450 - Manual (Page 5)

Jumper Selection
The CBC-400/CBC-450 controls can be operated in one of two modes either alternate (single) channel
operation or simultaneous (dual) mode of operation. In the single mode (alternate) of operation, channels
1 and 2 function alternately, one channel on at a time. In the dual mode (simultaneous) of operation, both
channels 1 and 2 function simultaneously, both on or both off at the same time.
In the alternate mode (single) at power up with no inputs active (all switching circuits open or off) channel
1 is the active output.
In the simultaneous mode (dual) at power up with no inputs active (all switching circuits open or off) both
channel 1 and channel 2 outputs are inactive or off.
Installation
The voltages present in this control can cause serious injury (even death). When installing
this control or any electrical equipment, make certain that the input power is off. Do not apply power to
this control until it is securely mounted and completely wired in accordance with local codes and all
installation work, including cleanup, has been completed.
