6. If a load return bus bar is ordered:
• Install the mounting bracket to the right upright of the cabinet
using M5 screws. Torque to 30 in·lbs.
• Attach two red standoffs to the bracket as shown for H569-436
(GPS4812/24) and H569-437 (GPS2424/30) or to the back studs
of bracket for H569-434 (GPS4848/100).
• Connect the L-shaped return bus bar (yellow paint on end) to the
vertical bus bar in the cabinet using M8 hardware. Torque to 120
in·lbs. Note: H569-434 (GPS4848/100) uses M8 screws,
lockwashers and washers while H569-436 (GPS4812/24) and
H569-437 (GPS2424/30) use M8 washers, lockwashers and nuts
as shown.
• Use two 1/4-20 x 5/8" screws to secure the bus bar to the

7. Locate the fuse/breaker ID label on the right side of the cabinet as
shown for H569-436 (GPS4812/24) and H569-437 (GPS2424/30)

8. Strap J2 on the BNL board should be across pins 1 and 2 for 48V
systems, and across pins 2 and 3 for 24V systems. The alarm cable
connected to P2 on the BNL board (yellow and orange wires)
should be connected to P1 on the BNL of the panel mounted above
this panel. If this is the first distribution panel installed in the
cabinet, then this cable may be discarded and a cable connected to
the BLJ3 terminal board on the door of the GPS should be
connected in its place. This cable has an orange wire connected to
DG and a yellow wire connected to FAJ on the BLJ3 board. This
cable should have sufficient length to reach the distribution panel.
