7. Initial operation of the UPS
The initial operation generally requires that all previous chapters of this manual
have already been successfully read or processed.
Additionally, check that all connected loads are switched off.
The initial operation of UPS devices is exclusively reserved for accredited per-
sonnel.
Please conduct the initial operation in the following order:
• Connect the UPS to the mains power supply;
The UPS then starts automatically. The UPS output remains switched off. The
operation display appears, accompanied by a signal tone.
• Connect the UPS to the load(s);
• Now switch the UPS on. The UPS immediately switches to the stand-
ard operating mode, the UPS is active, the load(s) is/are switched on.
Watch for a possible overload of the UPS;
• Monitor the operation display and messages of the UPS;
• Briefly test the autonomous mode under observation of the operation
display. Again, watch for a possible overload of the UPS;
• Switch the UPS back to the standard operating mode / charging
mode. You can now leave the UPS in this operating mode.
If the accumulator has been charged sufficiently, the UPS can carry out is sup-
port function accordingly.
• The sequence is conducted in reverse order to shut down the UPS.
In the event, errors occur during the initial operation, these must first be ana-
lyzed and removed before the initial operation can be continued.
