6. OPERATION.
6.1. sTarT-up.
6.1.1. Checks before start-up.
•
make sure that all of the connections have been made
correctly and with sufficient tightening torque, following
the instructions on the labelling of the device and in
•
Check that the UpS and battery module or modules
switches are ‘off’.
•
make sure that all loads are ‘off’.
Shut down the connected loads before starting
the UpS and start the loads, one by one, only
when the UpS is running. before shutting down the UpS,
check that all of the loads are ‘off’.
•
It is very important to proceed in the established order.
•
For views of the UpS, see Fig. 1 to Fig. 3.
•
In Fig. 18 , a distribution board with manual bypass is re-
presented conceptually for a parallel system, represent-
ative for a single device, with the number of switches
adapted.
6.2. ups sTarT-up and shuTdown.
6.2.1. ups start-up with mains voltage.
•
Check that the power connection is correct.
•
Supply voltage to the device (turn the input protection
on the distribution board or manual bypass to ‘on’. If the
board has an output switch, turn it to ‘on’.
•
Turn the battery switch to ‘on’ (models b0 and b1).
•
In 4 to 10 kvA models, turn the UpS’s input circuit breaker
located at the back of the device to ‘on’.
The output terminals will have voltage through
the device’s internal static bypass block.
The fan or fans, depending on the model, will start to
function.
Then the main start screen will be displayed after a test
of the device.
•
press the ‘on’ button for more than 2 seconds, the
audible alarm will sound for 1 second and the UpS will
start up.
•
The UpS is set to ‘normal mode’ after a few seconds.
If the mains voltage is incorrect, the UpS will switch to
‘battery mode’, without interrupting the power supply at
the output terminals.
•
Start the load or loads, making sure that the rated power
of the device is not exceeded.
6.2.2. ups start-up without mains voltage.
•
If it has a distribution board, turn the input and output
protections to ‘on’.
•
Turn the battery switch to ‘on’ (models b0 and b1).
•
Turn the device’s input circuit breaker to ‘on’.
•
press the ‘on’ button for more than 2 seconds, the
audible alarm will sound for 1 second and the UpS will
start up.
The fan or fans, depending on the model, will start to
function.
Then the main start screen will be displayed after a test
of the device.
on the 4 to 10 kvA models, it is necessary to press the
‘on’ button for a second time, about 5 to 7 seconds after
the first press, for longer than 2 seconds.
•
The UpS is set to ‘battery mode’ after a few seconds.
depending on the level of charge of the batteries, the
residual backup available may be very limited. Consider
the risk involved in operating without mains and
discharged batteries.
If the mains voltage returns, the UpS will transfer to
‘normal mode’ without interrupting the power supply at
the output terminals.
•
Start the load or loads, making sure that the rated power
of the device is not exceeded.
6.2.3. ups shutdown with mains voltage.
•
Shut down the load or loads.
•
press the ‘oFF’ button for more than 2 seconds to shut
down the inverter. The audible alarm will sound for 1
second. The device will be set to ‘bypass mode’.
The output terminals will have voltage through
the device’s internal static bypass block.
•
To cut the UpS’s output voltage:
disconnect the input plug of the power socket on
models up to 3 kvA and from 4 to 10 kvA and turn
the input circuit breaker located at the back of the
device to ‘off’.
or simply turn the input and output protections of the
UpS’s distribution board on any model to ‘off’.
A few seconds later, the LCd screen turns off and the
entire device will be out of service.
6.2.4. ups shutdown without mains voltage.
•
Shut down the load or loads.
•
press the ‘oFF’ button for more than 2 seconds to shut
down the inverter. The audible alarm will sound for 1
second. The device will leave the output terminals
without voltage.
A few seconds later, the LCd screen turns off and the
entire device will be out of service.
•
To leave the assembly completely isolated, turn the
input and output switches of the board to ‘off’.
6.3. operaTing proCedure For a parallel
sysTem (only in 4 To 10 kva models).
•
In parallel systems, check that the programming of
output 2 is the same on all of them to avoid conflicts.
•
The operating procedure established here is for devices
with a configuration determined by factory default.
•
Check that the load or loads and/or the output circuit
breakers on the distribution board are ‘off’.
•
Turn “on” the input circuit breakers on the distribution
or manual bypass board and those on each UpS in 4 to
10 kvA.
