Emerson 30-200kVA, 50 and 60 Hz, 400V Power Cables, Maximum steady state AC and DC currents

Single Module UPS Installation

1.6Power Cables

The cable design must comply with the voltages and currents provided in this section, follow local wir- ing practices and take into consideration the environmental conditions (temperature and physical support media).

For cable entry terminal, refer to Figures 43, 48, 52 and 56.

! WARNING

Before starting 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.

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