When the Circuit-Switcher is ready to be placed in service, the motor-and-closing
circuit fuses can—at the user’s option—be replaced with the enclosed slugs. This
practice is recommended for increased reliability because low-voltage fuses can be
damaged by the repeated inrush current experienced during normal Circuit-
Switcher opening and closing operations and can thus sneak out, leaving the
Circuit-Switcher inoperable.
Before replacing these fuses with slugs, make certain that the control-source
battery is adequately protected to prevent discharge, using fuses or circuit breakers
located at the battery bus.
