programmable/controllable. These instructions will list the always-on connections first, followed by the
programmable connections inside parentheses.
5.
Using Figure 20 , make these connections:
• Phase A cable from UPS Terminal 4 (9) to the downstream distribution panel Phase A on the
panelboard main breaker
• Phase B cable from UPS Terminal 3 (8) to the downstream distribution panel Phase B on the panelboard
main breaker
• Phase C cable from UPS terminal 2 (7) to the downstream distribution panel Phase C on the panelboard
main breaker
• Neutral cable from UPS terminal 5 (6) to the downstream distribution panel neutral bus
• The safety equipment ground cable from UPS Ground Stud 1 to the downstream distribution panel
ground bus
6. Replace the conduit box cover and secure it.
