Figure 11.7 shows the terminal mounting hole arrangement for the terminal buss strips for the 500 kVA
UPS units.
Figure 11.8 shows the arrangement of the terminal buss strips for the 500 kVA UPS. The buss strips are
located inside at the top of the unit. The dashed line on terminals 1–13 indicates the side view of the bolt
holes. Use 1/2 inch bolts to attach the lugs.
For UPS’ equipped with buss strip terminals for the A/C INPUT, BYPASS INPUT, A/C OUTPUT and
BATTERY connections, Toshiba recommends using the compression lugs listed in Table 11.3, or their
equivalent, for cable terminations to be mounted on the bus strips.
