W A R N I N G
Only qualified service personnel (such as a licensed electrician) should perform the electrical installation. Risk of electrical shock.
C A U T I O N
To prevent electrical shock or damage to the equipment, verify that the Powerware 9170 UPS is OFF before you remove the entrance panel. The circuit breaker or disconnect switch must also be off at the AC input service panel. Also, turn OFF the AC disconnect and bypass switches before you connect any wires to the bypass switch terminal strip.
1.Mount the bypass switch within sight of the UPS. If you do not have a Powerware bypass switch or the fuse box or panel is out of sight, you must install a separate disconnect switch next to the UPS.
The bypass switch should be mounted securely to a sturdy surface. You may need to turn the cabinet 90 degrees (on its side) to enable operator access to the switch handle.
2.Remove the six screws in the bypass switch front panel and remove the panel. Remove any packing material inside the bypass switch.
Remove knockouts in the bottom of the bypass switch for AC Line Input, AC to UPS Input, AC from UPS Output, and AC to the UPS load.
