10 Starting up the UPS equipment
To guarantee error-free startup, the following actions must be carried out:
1. Check the line-side fuse then connect the equipment to the power
supply.
2. Switch the UPS on (switch on the front of the equipment).
3. Wait until the UPS is in on-line mode.
4. Now connect the consumer loads one by one, observing the load
indicator. (Software)
If all of the steps have been completed successfully, the UPS will be in on-line
mode and the load must be less than 100%.
5. Now switch the system off (switch on the front of the equipment).
6.
Wait a few seconds (“refresh”).
7. Switch the UPS back on (switch on the front of the equipment).
The UPS equipment should revert to on-line mode after a few seconds. This
test ensures that the system will also start when the total load is connected.
Following this a power failure can be simulated by unplugging the mains power
supply. Here, too, the UPS must be able to operate the load without
overloading.
If the outcome of this test is positive, the system can remain in this status
ready for operation. Otherwise, the load at the output of the UPS must be
reduced and the system must be brought back into operation.
11 Troubleshooting
Troubleshooting on the UPS equipment may only be performed by authorised
technical personnel.
If the UPS does not work properly, try to resolve the problem by referring to the
