Ascertain that the breaker is completely powered down
during the Ground Alarm / Power Supply module
installation. If you unsure as to whether or not the unit is
isolated, contact a certified electrician.
5.2 Manually Tripping the Breaker
Before installing the Ground Alarm / Power Supply
module, manually force the isolated breaker to trip via the
push buttons on the front panel. Be advised that the
contact separation mechanism produces a very loud
sound during this operation. Use hearing protection at
your own discretion
6.0 INSTALLATION PROCEDURE
6.1 Removing the Front Cover
Using a 10mm rachet or driver tool, remove the four bolts
which affix the front cover to the breaker frame. These
are located at the four corners of the cover. Then pull
down the latch arm and lift off cover (per Fig. 6.1).

flat bladed screwdriver or fingernail. Using a 1/8" (3 mm)
wide screwdriver, loosen the M4 screw. Pull the door to
aid in releasing the rating plug from the unit. (Fig. 6.2)
