3.3 Connecting UPS Power Cables

WARNING

3.3.1Cable Entry

3.3.2Cable Rating

ØBefore cabling-up the UPS, ensure that you are aware of the location and operation of the external isolators that connect the UPS Input / Bypass supply to the mains distribution panel.

ØCheck that these supplies are electrically isolated and post any necessary warning signs to prevent their inadvertent operation.

Cables can enter the UPS modules and battery cabinet either from below or through either side. Side entry is made possible by removing blanking pieces fitted in the side ventilation grills to reveal the cable entry holes. This cable entry method allows the equipment to be positioned on a solid floor without the need for cable trenching and also allows cables to pass from one module to the other when positioned side-by-side.

When connected as a one-plus-one Non Redundant system, the UPS modules’ input and output cables must be rated to suit the supported load rather than the individual module’s power rating. This is due to the possibility of connecting the full load to the mains via the Maintenance Bypass line of one module.

In a Redundant system this is unnecessary as each module is individually rated to support the full load, and the input/output cables can be sized to suit the modules’ rating according to the table given below.
