them to maintain their available voltage. The BCU is designed for use in locomotives, 

heavy equipment, mobile applications and other battery installations.

 Before wiring or servicing the charging system, turn off the power and follow 

your organization’s lockout and tagout procedure. Failure to do so could allow others to turn on the 

power unexpectedly, resulting in harmful or fatal electrical shock.

CAUTION

!

Electrical hazard:

 Power source must be properly grounded and in accordance with national and 

local electrical codes.

or corrosion. Before installing, be sure you have the right charging system for your application. 

Carefully read all instructions before installing and energizing your system. The safety of any system 

incorporating this charging unit is the responsibility of the assembler. The safe and proper use of 

this charging unit is dependent upon the installer following sound engineering practices. If the 

equipment is used in a manner not specified by the manufacturer, the protection provided by the
