Transfer Voltage Selectors (DIP Switches)
The two-position DIP switch control on the rear panel, as shown
below, allows the operator to select the utility transfer voltage at
which the UPS will switch to battery power.
The factory default settings are 185VAC - 270VAC. DIP switch posi-
tions for each voltage setting are as follows:
DIP switch settings
Left Right Setting
↑ Up ↑ Up 185 - 270VAC (default)
↑ Up ↓ Down 185 - 280VAC
↓ Down ↑ Up 175 - 270VAC
↓ Down ↓ Down 175 - 280VAC
!
CAUTION
Never change the voltage settings while the UPS is ON and
powering connected loads. Change DIP switches only when
the UPS is OFF.
!
CAUTION
To ensure protection of the connected equipment, the DIP
switch settings should match the nominal utility input
voltage. DIP switch settings not matching the nominal
utility could potentially damage connected equipment.
