2. Customer Terminal Board – “CTB”
The following section does not apply to the Disconnect Drive Panels. All customer terminations for control
wiring are made on the drive’s connections. Refer to product user guide for details.
Inside the panel enclosure there is a terminal board for convenient connection of customer control wiring. The
customer interface drawing provides a visual reference of the terminal board positions with the detailed
descriptions as follows:
CTB1-1 through CBT1-3
Customer Safety Interlocks. Put normally closed contacts between CTB1-1
and CTB1-3. CTB1-2 and CTB1-3 provide an additional connection point if
required. An open circuit between these positions will cause the drive output to
stop and/or drive output contactor to drop out resulting in power being
removed from the motor. These positions come jumpered together from the
factory and require removal of the factory jumpers prior to connecting
customer normally closed contacts.
CTB1-6 through CTB1-7
Remote Run Input. Put normally open remote run contacts between CTB-6 and
CTB-7. Closure between these positions is required for the motor to run when
the Hand/Off/Auto switch is in the “Auto” position. The positions come
jumpered together from the factory.
CTB1-10 through CTB1-12
Drive Fault Contacts. Provides customer with a drive fault status via contact
closure. Form C contacts are rated 5A @ 240V AC, 24 VDC.
CTB1-13 through CTB1-15
Drive Start Status. Provides customer with a drive start status via contact
closure. Form C contacts are rated 5A @ 240V AC, 24 VDC
CTB1-16 through CTB1-17

WARNING: When the circuit breaker/disconnect handle is turned to the
“On” position, terminal board positions CTB-1 through CTB-3 can be at
115 VAC with respect to ground. Therefore, prior to making any
connections to these points lock the disconnect handle in the “Off”
position. In fact, good safety practice dictates that prior to servicing any
electrical equipment that all sources of electrical energy be
disconnected and “locked out” to avoid reconnection by a third party
unaware of the maintenance efforts underway.
