Bypass Operation
The bypass operation can be performed manually, using the maintenance bypass switch, or automatically, using
the PowerView to issue commands.
• In either bypass mode, the utility and circuit breakers must be turned on.
• The UPS must remain functional to stay in command bypass mode. Put the UPS in maintenance
bypass before turning off the system enable switch, or removing both intelligence modules.

CHAPTER 2: BASIC COMMANDS
Command Bypass
Command Bypass requires utilization of the commands on the PowerView display. This mode is used to bypass
the UPS electronics and directly supply power to the load.

Service
If the UPS requires service, do not return it to the dealer. Follow these steps:
1. Review the problems discussed in the Troubleshooting chapter to eliminate common problems.
2. Verify that the circuit breakers have not tripped. A tripped circuit breaker is the most common UPS
problem.
3. If the problem persists, call customer service or visit the APC Web site at http://www.apc.com .
• Note the model number of the UPS, the serial number, and the date purchased. A technician will
ask you to describe the problem and try to solve it over the phone, if possible. If this is not possible,
the technician will issue a Returned Material Authorization Number (RMA#).
• If the UPS is under warranty, repairs are free. If not, there is a repair charge.
4. Pack the UPS in its original packaging. If the original packing is not available, ask customer
service about obtaining a new set. Visit the APC web site for customer support telephone
numbers.
5. Pack the UPS properly to avoid damage in transit. Never use polystyrene beads for packaging.
Damage sustained in transit is not covered under warranty.
6. Mark the RMA# on the outside of the package.
