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
Chapter 5.
•
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, representative
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’.
