Powerware Powerware 9355 manual Terminal Block Wiring

TIE CABINET INSTALLATION

18.Hardwire the UPS input terminations.

See Table 1 for specifications and Figure 6 for a detailed view of the UPS terminal block.

NOTE Input neutral must be wired for proper operation or the UPS will not start.

NOTE The Powerware 9355 UPS is shipped as a single-feed UPS and can be converted to a dual-feed UPS in the field.

NOTE DO NOT overtighten the screws; be sure to use the specified tightening torque values shown in

Table 1.

1Use only 90°C-rated copper wire. Minimum wire size is based on 120/208 full load ratings applied to NEC Code Table 310-16. Code may require a larger AWG size than shown in this table because of temperature, number of conductors in the conduit, or long service runs. Follow local requirements.

2 Per NEC article 300-20(a), all three-phase conductors must be run in the same conduit. Neutral and ground must be run in the same conduit as the phase conductors.

3 Conduit is sized to accommodate one neutral conductor the same size as the phase conductor and one ground conductor. If two neutral conductors or an oversized neutral conductor are to be installed, check the size of the conduit needed to accommodate the extra wire or size and use that conduit size in place of the conduit size listed. Conduit sizes were chosen from NEC Table C1, type letters RHH, RHW, RHW-2, TW, THW, THHW, THW-2.
