5.3 AC VOLTAGE CONNECTIONS
To connect the input AC voltage, route the AC conduit
through the knockout hole provided. Continue the AC
wiring to fuseholder terminals L1 (N) and L2 (L) (single
phase input) or L1, L2, and L3 (three phase input),
ensuring that the AC source phases match the phase
rotation on the AC input. For proper connection, torque
the screws to approximately 25 inch-pounds.
5.4 GROUND CONNECTION
It is a requirement to ground the chassis while the
charger is connected to AC power. The charger comes
with a ground lug attached to the stud, clearly marked on
the chassis. To ensure good continuity keep the contact
area clean. The stud is designed for a 3/16” hardware.
See gounding method shown below (Figure 4.).
WARNING: DO NOT OPERATE THE UNIT
WITHOUT PROPER GROUNDING. IMPROPER
GROUNDING CAN RESULT IN THE RISK OF AN
ELECTRIC SHOCK.
CAUTION: USE MINIMUM 75°C WIRING. FOR
SUPPLY CONNECTIONS, GROUND CHARGER
PROPERLY USING GROUNDING STUD (GND)
PROVIDED. USE COPPER-CLAD ALUMINUM,
ALUMINUM OR COPPER CONDUCTORS ONLY.
After electrical connection is completed, the charger is
ready for operation.
NOTE: The following applies to three phase chargers
only: if the charger indicates “FAC” or “F3” upon start-
up, it means that there is a low or high AC voltage
(+35%) or AC phase missing. Refer to the
Troubleshooting section for more details.

6.0 DC OUTPUT
The DC charging cable has a commonly used battery
plug or receptacle. The polarity of the charger plug must
be the same as the battery connector. The BLACK DC
cable must be connected to the battery negative (-), and
the RED DC cable must be connected to the battery
positive (+). The charger will not operate in a reversed
polarity condition.
The DC output fuse is a "fast-acting" fuse used to
protect the power semiconductors of a charger.
NOTE: Use only identical replacement fuses obtainable
from your GNB service representative
