9. AC Output Breakers: Control output power to the PDU's AC output receptacles.
10. Maintenance Bypass Switch: Permits qualified service personnel to remove the PDU from the power module for routine maintenance
without disrupting power to the load. When this switch is set to BYPASS the load will receive unfiltered AC utility power and no

procedures.
WARNING! For qualified service personnel only. If the complete bypass procedure (see "Manual Bypass Operation," p. 10) is
not followed, the UPS will not be adequately powered down, presenting a risk of death or serious injury from contact with high
