4 Service operation
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.
4.2 How to disconnect cables between MBP and UPS
This is to disconnect ‘cables for UPS Input / Output’ and ‘MBP detection cable’.

5 Specifications
1. Electrical input—refer to the UPS input specification.
2. Electrical output—refer to the UPS output specification.
| Output socket group | Normal output | 10A & 16A |
| Programmable output | 10A & 16A |
Outlet socket group (Programmable) can be set on the LCD or by sending command; it could be sent between “always on” and “auto off-on”, and “always on” by default.
Once it is set as “auto off-on” that output power will turn off when battery capacity below 50% in battery mode, and outlet socket group (Programmable) will turn on again when charger begins to work.
