Step 5: Wire the Field Connections
A. Drill conduit entry holes as needed, and install conduit grounding lugs for each opening. Be sure
to reseal unused conduit entry holes with sealing plugs.
NOTE
: Main supply
conductors may enter the
Enpower from the bottom or
from the bottom-left side.
Backup load conductors
may enter the Enpower from
the bottom or bottom-right
side. Encharge, Combiner
and generator (reserved for
future use¹) conductors may
enter from the bottom,
bottom-left or bottom-right
sides.
B. Size the conductors (Line,
Neutral and Ground) depending
on the breaker or fuse, proper
ampacity, and voltage rise
requirements according to local
codes. Refer to the conductor
rating table on the door of the
Enpower.
DANGER
! Risk of electric shock. Check that all circuits connecting to the Enpower are de-
energized before wiring.
C. If the Enpower is not installed as service equipment
2
, you must remove the main bonding jumper
connected between the grounding bar and the neutral assembly. Refer to the wiring diagram.
NOTE
: Do not modify or rewire any of the other pre-installed wiring or bonding connections in
the Enpower.
D. If Enpower is installed as service equipment
2
:
•
Connect a grounding electrode conductor to the grounding bar.
•
From the lit kit, place the label “GROUNDING ELECTRODE TERMINAL” adjacent to
the grounding bar.
•
From the lit kit, place the label “SUITABLE FOR USE AS SERVICE EQUIPMENT” /
“MAIN SERVICE DISCONNECT” on the deadfront near the main breaker/service
disconnect.
•
If Enpower is not used as service equipment, these labels should not be used.
E. Connect Lines, Neutral, and Ground. For details, refer to the conductor table on the unit for sizes
and refer to local codes.
WARNING
! Risk of equipment damage. Always connect to two Lines (active), one neutral,
and one ground.
