WARNING! 

– 

READ SAFETY NOTICE ON PAGE 11 BEFORE ATTEMPTING TO 

USE THIS CONTROL. WIRE CONTROL IN ACCORDANCE WITH THE NATIONAL 
ELECTRIC CODE REQUIREMENTS AND OTHER CODES THAT APPLY. BE SURE TO FUSE 
EACH CONDUCTOR WHICH IS NOT AT GROUND POTENTIAL. DO NOT FUSE NEUTRAL 
OR GROUNDED CONDUCTORS.  

 

         

WARNING! TO AVOID ERRATIC OPERATION DO NOT BUNDLE AC LINE AND     

          MOTOR WIRES WITH POTENTIOMETER, VOLTAGE FOLLOWING, ENABLE, INHIBIT OR   
          OTHER SIGNAL WIRING. USE SHIELDED CABLES ON ALL SIGNAL WIRING OVER 12" (30 
     CM) – DO NOT GROUND SHIELD. 

 

 

 

Connections to the control (BC-154 / BCWD140) should be in accordance with the National 
Electric Code requirements, and other codes that apply. Be sure to fuse each conductor which 
is not at ground potential. 

Do not fuse neutral or grounded conductors

. Refer to the Section 

4.1. 

 

A separate AC line switch, or contactor, must be wired as a disconnect switch, so that the 
contacts open each ungrounded conductor. An accessory ON/OFF AC Line Switch (KB P/N 
9341) may be installed in this control in lieu of, or in addition to, the Start/Stop Switch normally 
provided. The switch can be wired for double pole or single pole operation. (See Figure 5, on 
page 17, for AC Line and Armature connection.) 

 
 

To maintain the watertight integrity of the control, be sure to use suitable watertight connectors 
and wiring, which are appropriate for the application. Two .875" (22.2 mm) knockout holes are 
provided for a standard 1/2" knockout connector (not supplied) for wiring. A watertight plug is 
provided if only one knockout is used. 

 

4.1   Fusing 

 

 

4.1.1   AC Line Fusing – 

Most electrical codes require that each ungrounded conductor  

       contain  fusing. Separate branch circuit fusing or circuit breaker may be required.   
           Check all

 

electrical codes that may apply to the installation. This control does not  

   

          

contain AC line fuses. A 25 amp rated fuse or circuit breaker can be used. 

 

4.1.2    Armature Fusing - 

The correct size armature fuse 

must be installed

, depending  

         on the rating of the motor. 

Control will not operate if fuse is not installed. 

Fuse 

         type should be Littlefuse 326 ceramic, Buss ABC, or equivalent. A fuse chart is       
     presented below which suggests appropriate armature fuse ratings. However, the  
     specific application may require larger fuse ratings based on ambient temperature, 
         CL set point and duty cycle of operation. (See Table 7, on page 17.) (Fuse rating is 
         based upon 1.7 times the motor current rating.)
