Table 3. Bypass Switch Positions
Switch Position | Description |
|
|
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. |
