Dell UPS Site Preparation Guide, EMEA (230V) Revision 2, December 2012
Overcurrent Protection Devices:
All Dell UPS Rack Mount Models (except 5600W Online and 10kW):
In all cases the installation should include a dedicated electrical branch circuit with a 2-pole overcurrent protection
device. The breaker should be wall-mounted and accessible to the operator.
5600W Online and 10kW UPS:
The 5600W online and 10kW UPS does not have an automatic protection device against current backfeed. Dell
recommends installing an external isolating device (see illustration below). After the device is installed, you must add
a warning label with the following wording or the equivalent on the external AC contactor:
“RISK OF VOLTAGE BACKFEED. Isolate the UPS before operating on this circuit, then check for hazardous voltage between all
terminals.”
