D. While supporting the deadfront, use a
screwdriver to disconnect the deadfront
ground wire from the grounding bar before the
deadfront is removed.
E. Use the two tabs on the front to assist
handling the deadfront during the removal.
Keep the deadfront and screws handy as you
will need them later.
WARNING
: Risk of electric shock. To
maintain the warranty, do not modify the
deadfront other than to remove or replace
filler plates, as needed.
F. If you install a main breaker or load breaker,
remove the standard lugs before installing the
Eaton CSR breaker. By default, lugs are
provided in the Enpower unit for connection to
the mains and to the load. In case of usage
without breakers, the conductors are
connected directly to these lugs. When
breakers are used, the lugs are replaced with
breakers during installation.
G. Remove a filler plate from the deadfront for each breaker position you will use. Refer to the
breaker position diagram. To remove the filler plate, press the two snaps inward while gently
pushing the filler plate out.
H. For the Encharge, AC Combiner or Generator (reserved for future use¹) connection, snap the
appropriately sized BR series two-pole Eaton breaker onto the busbar, using only the breaker
positions indicated in the diagram on the door of the unit. Breaker functional position are not
interchangeable with one another. The wires to be connected to each breaker are located beside
each breaker position. Remove the heatshrink cap on wire ends before inserting into the breaker.
I.
Install each breaker by rocking it to the left, catching the clips that hold it in place. Then rock the
breaker to the right so it is fully seated and secure.
J. For the main load breaker, use an appropriately sized CSR Eaton breaker. Install at the location
indicated in the
diagram on the
door of the unit.
K. Remove the
mains/load lugs by
unscrewing (use a
1/4” hex drive) the
two nuts holding
the lugs. Re-use
the same nuts to
fix the CSR
breakers in the
same position.
Torque to 4
N•m
(35.4
lb•in).
L. Use the M4 screw
(from the lit kit marked 150-00148 that ships with the Enpower) to secure the mains breaker (not
the load breaker). Use a T20 drive to tighten the M4 screw to 1.5 N•m (13.3 lb•in). Do not use any
other screw.
