5.2 – START-UP
DANGER
, do not touch output terminals
The UPS contains batteries. The output terminals may be electrically live, even when the UPS is
disconnected from the utility supply. Dangerous voltages may be present during battery operation.
NOTE
The UPS can be started on battery power if the utility input voltage is not available or if circuit breaker
‘utility’ is in off-position: simply skip step 1.
To prevent accidental discharging of the batteries, it is however recommended to proceed with step 1
and start the unit only when the utility input voltage is available
The numbers between (brackets) refer to figure 19 in section 5.1.
1. Turn breaker 'utility' (8) and breaker 'bypass' (9), both on the rear panel, into position ‘on’ (up).
2. Some UPS parameters (e.g. voltage, frequency, LCD language) are user selectable. If you want to change one or more
settings, please refer to section 5.4.4 ‘Set-up Menu’ now. Changing the settings later is possible, however only after
switching off the unit.
3. Turn switch 'UPS on/off' (7 in Fig.19) into position ‘on’ (up).
The green LED 'operation' (front panel, 5) will illuminate.
After switching on the UPS performs a self-test and the display (front panel, 1) will show:
SELFTEST
IN PROGRESS
After completion of the self-test the output voltage of the UPS is available and the unit is ready for use. The display will
show the default screen: model and actual load (values are examples)
LP 6-11U 924
LOAD 37%
In case of a system failure the self-test results in a failure message; this message is displayed for 30 seconds before the
self-test is repeated automatically. If the faulty situation persists, switch off the UPS and contact your dealer. See chapter
9 for more information.
If you start up a parallel system please refer to section 4.5.5.2 for additional information.
4. Though the batteries were fully charged when the UPS left the factory, they might have lost some energy during
transport and/or storage. It is recommended to allow the UPS to recharge the batteries for a few hours. This way you
ensure that the UPS can provide sufficient runtime in case of a utility power failure.
5. Check the position of the manual bypass switch (10 in Fig.19).
If it is in position “2”, turn it into position “1”.
6. If not yet switched on, the equipment connected to the UPS can be switched on now; operate as usual.
