9.2.2 Switching-off and power down the UPS
To switch the UPS off, the buttons (3) “Menu-down” and (4) “Menu-up” have to
be pushed for about 3sec at the same time. At the same time the UPS will be
in loading-service to keep the accumulators loaded and ready for service. To
achieve a completely disconnection of the UPS, the line cord of the unit has to
be plugged-out.
9.2.3 Changing the basic setting
Before changing basic settings, you should observe the following points:
o
False settings can damage the UPS or the consumer loads.
o
Be informed about the technical data of the connected consumer
loads.
o
All consumer must be disconnected to the charge output.
o
Ensure that the UPS is switched-off.
o
The new settings will first be adopted after a complete new start of
the UPS (switching-off, disconnect the line cord and then connect it
again).
Basic
settings:
Following parameter can be changed in te basic settings:
Switching threshold for the bypassing mode (lower switching threshold
176V +/-20V; upper switching threshold 253 +/-20V).
Output voltage (210V; 220V; 230V; 240V AC).
Output frequency (50Hz; 60Hz) in battery service;
input frequency has to be adapted.
Active or inactive bypass in switched-off condition (inactive = xxHz;
