EQUIPMENT DAMAGE The Auxiliary AC input voltage supplied to the High Voltage Box (HVB) and Thermal Management System (TMS) must not exceed 275 Vac. Overvoltage can damage the equipment and void the warranty. Failure to follow these instructions may result in equipment damage. |
AC Supply Rating: Use wiring rated for up to 30 A continuous. A 32 A miniature circuit breaker acts as a disconnect for the High Voltage Box (HVB) and auxiliary systems. The wiring is terminated within an AC junction box near the top of the HVB.
Voltage Limit: Supply voltage must be single-phase, 200–275 Vac. Do not exceed 275 Vac. Suitable supply from 208V or 240V single-phase input.
Transformer Use:
-
If needed, use a step-down transformer to provide 208 or 240 Vac.
-
A transformer can be single-phase or three-phase, but each HVB requires only a single-phase input.
-
Minimum transformer size: 5 kVA for single-phase.
-
A transformer may serve multiple AES battery cabinets if adequately sized and wired.
