NOTE In the UPS or LINE position, AC input power is still connected to the input terminals
inside the UPS.
Table 3. Bypass Switch Positions
Switch Position Description
LINE Connects the load directly to AC input pow er and disconnects UPS output. AC input power is
still connected to the UPS input.
OFF Disconnects the load from the UPS output power and AC input power, as well as AC input
power to the UPS input.
UPS Connects the UPS output to the load.
SERVICE Like the LINE position, SERVICE connects the load directly to AC input power and disconnects
UPS output. However, because SERVICE also disconnects AC input from the U PS, this is
the appropriate position for UPS maintenance or repair.
To disconnect AC input power during maintenance or service, turn the
bypass switch to the SERVICE position. For MBB switches, you must
press the red button beside the switch before you can change the
switch position.
