Specifications for 480 V Systems

In single mains systems, supply the UPS from a grounded 4-wire WYE service.

Schneider Electric also supports 3-wire single mains installations if the mains transformer is a grounded WYE transformer located in the same building. In this installation, the UPS system must be installed as a separately derived system. Leakage currents will occur in the bonding jumper and the technical/system earth.

In dual mains systems, use a 4-wire supply for the bypass and a 3-wire supply for the input. Both must be WYE sources. Delta input supply for either input or bypass is not permitted.

Recommended Cable Sizes 480 V

DANGER
hazard of electric shock, explosion, or arc flash
All wiring must comply with all applicable national and/or electrical codes. The maximum allowable cable size is 1/0 AWG.
Failure to follow these instructions will result in death or serious injury.

The maximum number of cable connections per busbar: 2 on input/output/bypass busbars; 2 on DC+/DC- busbars; 4 on N busbar; 5 on PE busbar.

NOTE: Overcurrent protection is to be provided by others.

Cable sizes in this manual are based on Table 310.15 (B)(16) of the National Electrical Code (NEC) with the following assertions:

  • 90 °C (194 °F) conductors (75 °C (167 °F) termination)

  • An ambient temperature of 30 °C (86 °F)

  • Use of copper conductors

If the ambient temperature is greater than 30 °C (86 °F), larger conductors are to be selected in accordance with the correction factors of the NEC.

Equipment grounding conductors (PE in this manual) are sized in accordance with NEC Article 250.122 and Table 250.122.

NOTE: The DC cable sizes given here are recommendations – Always follow the specific instructions in the battery solution documentation for DC+/DC- and DC PE cable sizes and ensure that the DC cable sizes match the battery breaker rating.

CAUTION
hazard of fire
  • Connect only to a circuit with the below specifications.
  • Connect to a circuit provided with a 125 A branch circuit overcurrent protection maximum in accordance with the National Electrical Code, ANSI/NFPA70, and the Canadian Electrical Code, Part I, C22.1.
Failure to follow these instructions can result in injury or equipment damage.
