The following information and instructions are to be used as a supplement to the
KBPW-240D Installation and Operation Manual Rev. A (Part No. A40360). The manual
must be read and understood before attempting to operate this control.
The PC board has been upgraded to include provision for normally open or normally
closed stop contacts and to connect an Enable switch. The General Performance
Specifications have not changed.
Jumper J6 (Stop Switch type "NO" or "NC" Selection) and Jumper J7 (Enable
Selection) have been added. Enable terminals have been added to Terminal Block
TB3. Also, Figures 7A and 10A have been added.

G. Remote Start/Stop Switch Connections
The control is supplied with a prewired Start/Stop Switch with a normally open "NO"
stop contact. Jumper J6 is factory set to the "NO" position.
For remote 3-wire Start/Stop Switch with a normally closed "NC" stop contact, connect
the switch as shown in Figure 7A, below. Set Jumper J6 to the "NC" position.

K. Enable Connection
Wire the Enable contact to Terminals "EN1" and "EN2" of Terminal Block TB3 as
shown in Figure 10A, below.
The Enable is used to electronically start and stop the control. When the Enable
contact is closed, the control will accelerate to the Main Speed Potentiometer setting.
When the Enable contact is opened, the control will coast to stop.
Note: The contact must be isolated from the AC line and Jumper J7 must be removed.
