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.












CTB1-4
through CTB1-5

Provides customer with “drive ready to run” status via contact closure. Panel
conditions that provide contact closure are; 1) drive output contactor is

energized with drive not faulted and 2) drive has been issued a run command.

Typical use for this status is “drive enabled” ready for speed reference to output

power to the motor. Contacts are rated 5A @ 240V AC, 24 VDC.


CTB1-6
through CTB1-7

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

Provides customer with a drive fault status via contact closure. Contacts are
rated 5A @ 240V AC, 24 VDC.


CTB1-13 through CTB1-15

Provides customer with a drive running status via contact closure. Contacts are
rated 5A @ 240V AC, 24 VDC


CTB1-14
through CTB1-15

Place normally open contacts between CTB-14 and CTB-15. Closure between
these contacts cause the motor to run at a preset speed (speed programmed

by function code C20) from the drive. A typical use for this input is a smoke

purge command.

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.
