SECTION 100: STARTUP AND SHUTDOWN

To avoid possible personal injury or equipment damage, assume that there may be AC
voltage at the UPS's output terminals / receptacles any time AC input power or DC battery
voltage is applied. The UPS can provide output voltage from the batteries even when there
is no AC input line voltage. When AC voltage is present, the UPS can provide output
voltage even when the batteries are disconnected. If you want to be certain that there is no
UPS output voltage, always disconnect the AC input source, switch off the UPS, AND
switch off the DC. TEST BEFORE TOUCHING!
Some units have been programmed at the factory for autostart. When this parameter is
programmed to be on, the unit will automatically switch on whenever mains (AC line) is
applied. To switch this parameter off, see Section 205.
For safety reasons, only qualified service personnel should do a complete startup or shutdown of the
UPS whenever this is necessary. The qualified service person should follow the instructions in the
Planning and Installation Manual. The UPS must be completely shut down before service or before
the UPS is taken out of operation for more than 24 hours.
Although users cannot completely start or shut down the unit, they can switch the UPS into standby
mode and return it to normal operation by following the instructions below. (In standby mode, the
UPS does not provide output voltage.)
To put the unit into standby mode, press the red control button inside the unit's front door.
To take the unit out of standby and switch it back to normal operation, press the green control
button inside the unit's front door.
NOTE: Make sure the UPS operates in the normal mode for at least 12 hours every three months to
recharge the batteries.
CAUTION!
