Ac Service Requirements; Grounding The Charger - Ferro Q Installation And Operation Manual

1.4. AC Service Requirements

Follow local code requirements if they are different than the instructions in this manual. Refer to Table 1-1, to
determine the correct 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.
"CAUTION" – Risk of fire. Use only on circuits provided with 30 amperes branch circuit protection in
accordance with the National Electrical Code, NFPA70.

For voltages up to 240, use a 240 volt disconnect switch.
For voltages greater than 240 to 600, use a 600 volt disconnect switch.
Three conductors and ground wire required for three-phase
1.5. Connecting AC Service to the Charger
Three-Phase Models
Connect the AC service to the L1, L2 and L3 terminals located on the AC connection block.

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.
