LINE Connects the load directly to AC input power 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 UPS, 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.
There are six bypass switch models available for the Powerware 9170
UPS as specified in Table 4.
