or constant voltage mode (temperature compensated, available as an option) based on battery condition.

All batteries used in conjunction with the Powerware 9335 are external to the UPS cabinet. The internal charger charges the entire battery system, with a maximum current as indicated in Chapter 13, “Product Specifications”. Note that the higher the battery capacity, the longer the recharge time required to fully recharge the batteries.

5.3.5 Static Bypass

The bypass has a continuous-duty SCR switch and a back-feed contactor (K4) in the Bypass circuit. In normal mode, the contactor connects the inverter to the output. A contactor (K2) provides isolation to the inverter when the system is on bypass.

5.3.6 Maintenance Bypass

A user accessible shrouded 4-wire Mechanical Maintenance Bypass switch is provided internal to the cabinet.
