1.4. AC SERVICE REQUIREMENTS
Follow local code requirements if they are different than the in structions in this manual. After ch ecking
the transformer connections as d escribed in Parag raph 1.3, refer to Table 1-1, to determine the corre ct
ratings for the AC cable, AC fuses, and AC service disconnect switch for the line amperes as listed on the
nameplate of the charger for the available AC voltage

For voltages up to 240, use a 240 volt disconnect switch.
For voltages greater than 240 to 600, use a 600 volt disconnect switch.
•
Two conductors and ground wire required for single phase.
•
Three conductors and ground wire required for three-phase
1.5. CONNECTING AC SERVICE TO THE CHARGER
1.5.1. SINGLE-PHASE MODELS
Connect the AC service to the L1 and L2 terminals located at the end of the AC fuse block.
Note:
If the charger has been ordered with an AC input door-mounted disconnect switch, the AC input
wires will be connected to the L1 and L3 terminals at the top of the switch body.
1.5.2. THREE-PHASE MODELS
Connect the AC service to the L1, L2 and L3 terminals located at the end of the AC fuse block.
Note:
If the charger has been ordered with an AC input door-mounted disconnect switch, the AC input
wires will be connected to the L1, L2 and L3 terminals at the top of the switch body.
1.6. GROUNDING THE CHARGER
The charger must be grounded to the AC system ground for personnel safety.
The green ground wire in the AC input wiring must be connected to the charger ground stud
(Identified by a green dot and ground symbol).
1.7. BATTERY CONNECTOR AND CHARGING CABLE
Verify that the connectors on both the battery and the charger are attached so that the positive output
terminal of the charger is connected to the positive battery terminal.
CAUTION:
If the polarity is reversed, the DC fuse will blow. If in doubt, check the polarity with a
DC voltmeter.
1.8. CHARGING RATE ADJUSTMENT
The charging rate has been set at the factory; therefore, field adjustment should not be necessary.
Consult factory.
