Rack Requirements for the Dell UPS

Dell Rack UPS are suitable for installation into 19” 4-post racks. Reserve space for UPS and EBM at bottom of rack.

Rack types supported are: EIA/ECA-310-E (includes Dell and other common rack suppliers); and, support 4-post square or round (non-threaded) type holes. If round hole, use rack with 7.0mm diameter (unthreaded). The Dell rack UPS and rack EBM include ReadyRails with a minimum retraction of 517 mm (20.35") and maximum extension of 783 mm (30.8").

5600W Rack	Online	208, 220, 230, 240		143W	32 Amp 1-phase	8.36 / 5.26 mm2
10kW Rack	Online			60W	63 Amp 1-phase	21.14 / 8.36 mm2
			208, 220, 230, 240

Note: Overcurrent protection should be ‘slow-break’, suitable for devices with a high inrush current. Normally this should be a fuse or circuit breaker with a Type-C or Type-3 rating.

Electrical Requirements for the REPO Switch (Remote Emergency Power Off)

REPO is used to shut down the UPS from a distance. For example, this feature can be used for shutting down the load and the UPS by thermal relay, in the event of room over-temperature. When REPO is activated, the UPS shuts down the output and all its power converters immediately. The UPS logic power remains on to issue an alarm.

1Supported UPS are 3750W, 4200W (Online) and 5600W (Line Interactive) models. 5600W Online and 10kW Online UPSs do not have an input cord option.
