Specifications and Technical Data

11.4UPS Electrical Characteristics

Refer to additional circuit breaker notes in 3.2.7 - Accessory Fuses and Backfeed Breaker Wiring.

NOTE

The breakers and cables used must be in accordance with NEC ANSI/NFPA 70. A disconnect breaker must be provided for AC input, DC input and AC output. Recommended cable sizes are suitable for operation at a maximum temperature of 86°F (30°C). For continuous operation at temperatures above 86°F (30°C), the site design should include cables that meet requirements for 104°F (40°C) installations.
