Hardwiring the UPS Input
WARNING: Only qualified service personnel (such as a licensed electrician) shall perform the electrical
installation. Risk of electrical shock.
The Dell Online Rack hardwired models require a dedicated branch circuit that meets the following
requirements:
S 250V/30A, 2-pole circuit breaker (25A for 3750W/230V UPS models) to provide short circuit and
overcurrent protection
S The protection device requires a two-pole disconnection device between the UPS output and the
load (see Figure 6)
S The breaker must be wall-mounted and be readily accessible to the operator
S For Europe, the breaker must meet the IEC/EN 60934 standard and have a contact air gap of at
least 3 mm
S 200–240 Vac
S Single-phase (4200W/208V model is split-phase)
S 50/60 Hz
S Flexible metal conduit (recommended for ease of service and maintenance)
