Next, loosen the two screws at the bottom of the steel
Trip Deck Mounting Plate. Lift the plate upward then
swing it to the left to expose the cavity where the Ground
Alarm / Power Supply Module will be mounted.
7.0 MOUNTING THE MODULE
Take one of the supplied self tapping screws and partially
screw it into the bottom retaining boss for the module.
The screw anchoring tabs for the module are slotted.
Slide the bottom tab of the module behind the partially
inserted screw. Take the second screw and place it in the
other slotted notch on the top of the module and anchor
the unit in place in the breaker. Now go back and tighten
the bottom retaining screw and ascertain that the Ground
Alarm / Power Supply Module is firmly seated in the
Magnum frame.
8.0 WIRING HARNESSES
Two wiring harnesses must be attached to the Ground
Alarm / Power Supply Module. The first, a three conductor
connector, is already pre-wired into the breaker at the
8.1 Preparing the Harness
Using the supplied tie wraps, secure the four conductor
harness into a tight and neat bundle. Cleanly trim the
excess tails from the tie wraps.
CAUTION
IT IS IMPORTANT THAT THE TIE WRAPS ARE
TRIMMED AND THAT THE NEW HARNESSES AND
EXISTING WIRING BE TUCKED NEATLY BACK INTO
THE BREAKER FRAME. LOOSE OR STRAY WIRES
MIGHT INTERFERE WITH PROPER FIT AND ALIGN-
MENT OF THE TRIP UNIT. ADDITIONALLY, THIS
SAME SITUATION MIGHT INHIBIT MOVEMENT OR
OPERATION OF CERTAIN MECHANICAL COMPO-
NENTS WITHIN THE BREAKER.

8.2 Running the Harness
Insert the end with the four pins behind the Ground Alarm
Power Supply Module from the left side. Feed that end up
behind the module between the bosses that secure the
Trip Unit and the module itself.
8.3 Attaching Harnesses to the Module
Take the pre-wired, three conductor connector with the
locking edge faced up and push firmly into place on the
three conductor pin set (J3) on the left side of the top of
the module. Confirm that the connector is locked in place.
Next, take the four conductor connector and similarly
attach it to the four conductor pin set (J4) on the right side
of the top of the module. Ascertain that it is secure.
8.4 Wiring the Secondary Block “A”
The ends of the four conductor harness are to be
connected to the Secondary Block “A” on the top, left side
factory. The second is supplied with the field installable
upgrade kit. It comes ready to install with a four conductor
connector on one side and male pins on the other which
are inserted into the Secondary Block “A” which is a black
connector on the top left side of the breaker.
