SWMB
The mechanical bypass switch SWMB must not be closed during normal operation of the UPS.
SWMB should only be closed during UPS maintenance operations in order to keep the load
powered (see the instructions on page 37).
When the UPS is first started up, it is in on-line mode (see page 36 ). See pages 36 and 72 to set Standby-on / Smart
active operating mode.
configurations
Contact the factory for other operating modes.
Once the UPS has been installed, check that the message NORMAL OPERATION appears on the first line of the
display panel.

Battery operation check
Carry out only with battery present.
After installation, a mains outage even of just a few seconds can be simulated to check operation. The battery
does not need to be charged to perform this test.
With the UPS in normal operation, open switch SWIN located at the UPS input (rectifier). The buzzer should
sound immediately. The display on the CONTROL PANEL should appear similar to the picture shown on page
56 of this manual (with 5=ON). OUT. (Green LED) and BATT. (Yellow LED) on the Signals and Commands
Panel should be ON.
Check that the load connected to the UPS is powered. In this mode, the power supplied to the load is being
provided by the batteries. Close the input power switch SWIN to return to normal operation. The IN. and
OUT. LEDs on the CONTROL PANEL will be GREEN. The batteries will recharge automatically.
Battery backup time
Before a full battery discharge test can be carried out, the battery must be charged to full capacity.
Charge for at least eight hours for standard backup times or longer for batteries sized for long backup
times to allow the batteries to charge.
The backup time obtained on the first discharge may be slightly less than expected; a number of
charge and discharge cycles needed to improve this value.
Battery capacity does not remain constant over time, but increases after some charge and discharge
cycles; it then remains constant for several hundreds of cycles before decreasing permanently.
Battery life will be reduced if the battery is operated at temperatures greater than 20
o
C.
Operating modes
The various UPS operating modes are described below.
setting
The operating mode is set when the UPS is installed; it may be changed subsequently but this should
always be done by a
qualified service technician.
