4.1 How to switch system to BYPASS mode
Please make sure the UPS is turned to bypass mode before rotating the maintenance
switch to bypass position.
1. Remove the ‘Maintenance switch cover’, the UPS will turn to bypass mode
automatically.
2. Rotate the maintenance switch to ‘’BYPASS’ position.
Note:
For an unconscious operation, it is recommended to install back the ‘Maintenance
switch cover’ as above to prevent 'BYPASS’ switch back to ‘UPS-mode’.
3. Turn the MBP ‘input switch’ to ‘OFF’ position.
4. After these operations, the MBP will power the load directly via maintenance
switch.
