UPS Stop/Start

2.0 UPS Stop/Start

WARNING!

AC voltage generated either from batteries or utility may be present at UPS output. Always disconnect AC input supply source, switch off UPS, AND switch off DC.

TEST BEFORE YOU TOUCH!

Some UPS systems have a factory-set auto-start feature, which automatically switches on the UPS whenever utility supply is switched on (AC line). See the “Parameter Settings” section in this User Guide for instructions on how to de-activate this function.

Only qualified electricians should start up or shut down APC BC300 Series UPS systems, and instructions in the Installation Guide should be followed. The UPS must be completely shut down before service or before the UPS is taken out of operation for more than 24 hours. Although you cannot completely start or shut down the unit, you can switch the UPS into stand-by mode and return it to normal operation by following the instructions below. (In stand- by mode, the UPS does not provide output voltage.)

2.2UPS Start (from stand-by)

NOTICE!

Make sure the UPS operates in normal operation for at least 12 hours every three months to recharge the batteries.
