Remote EPO Switch Dimensions3.2.3 UPS System Power Wiring PreparationRead and understand the following notes while planning and performing theinstallation: Refer to national and local electrical codes for acceptable external wiring practices. To allow for future kVA upgrades, consider installing a derated UPS using wiringand external overcurrent protection breakers sized for a fully rated UPS. To allow for a future upgrade, install a three UPM model using conductors andexternal overcurrent protection breakers sized the same as a fully rated 1200 kVAmodel. For external wiring, use 75°C copper or aluminum wire. Wire sizes listed inTable 3‐5 through Table 3‐8 are for copper wiring only. If wire is run in an ambienttemperature greater than 30°C, higher temperature wire and/or larger size wiremay be necessary. Wire sizes are based on using the specified breakers. Wire ampacities are chosen from Table 310.15(b) (16) of the National ElectricalCode® (NEC®). Specification is for copper wire with a 75°C rating. Material and labor for external wiring requirements are to be provided bydesignated personnel. If installing a maintenance bypass, a minimum of two separate feeds withupstream feeder breakers, or a single feed with two upstream feeder breakers,must be provided: one for the UPS or rectifier input breaker (RIB) (if installed) andone for the maintenance bypass input. DO NOT use a single feed or a single feederbreaker to supply both the UPS or RIB and the maintenance bypass. If a bypassinput breaker (BIB) is installed in the maintenance bypass and a single-feed UPS isbeing installed, a single feed to the maintenance bypass is acceptable for supplyingboth the UPS and the bypass. The bypass and rectifier feeds into this equipment use three wires for the 480V,and four wires for Bypass for the 415/400/385V models. The phases must besymmetrical about ground (from a Wye source) for proper equipment operation. The Eaton 9395P-1200 480V unit is designed for operation on a grounded-wyesource of supply. There is no additional connection point for a neutral conductor.The output of this UPS will not directly support phase to neutral loads.
