Installation - LEGRAND WHAD 3 100 96 Manuel D'installation

The following connection points are located on the rear of the UPS:
• Input/output plug-socket [3]: connect the power supply cable and the output extension sockets
to this connector, as indicated in the diagram.
• Socket for connection of RS 232 (9 pin female) type, computer serial interface [5]: to be used if
the 'SuperviSor light' UPS diagnostics software is required.
• 1 socket to connect the remote control and the computer interface to logic signals ( contacts)
[4]: for use with the respective accessoires (optional)
WArning
For reasons of safety, we recommend the cables supplied are not modified; in addition it is
essential to ensure that the mains outlet used for the UPS is connected securely to the earth
circuit.
WArning
The mains outlet, or the circuit breaker, must be installed near the appliance and must be
easily accessible.
3.1 Proceed with the installation as follows:
1. Locate the UPS so that the ventilation outlets are not obstructed.
2. Connect the power supply cable and the multiple-socket, output extension to the Input-
Output connector [3] (see fig.1)
3. Check that the on/off switches of all the appliances to be connected to the UPS are OFF and
connect them to the output extension.
4. Insert the power supply plug into a power outlet that is adequate for the voltage and current
required.
3.2 switching on
1. Switch the UPS on with the appropriate button [1] (refer to the section on 'Functions and Signals'
at the paragraph 'controls'): The UPS initially supplies the output directly with mains power using
its bypass (signalled by the yellow LED) [2] and after a few seconds switches over to its inverter
and enters its normal operation mode (the green MAINS LED [2] is on).
2. Switch the connected loads on and, after any bypass intervention, check that normal operation
is resumed: at this point the green MAINS LED [2] is on. Should the connected loads be too large,
the bypass will remain active and the red ALARM LED [2] will flash.
3. A few moments after switching on, the UPS will automatically test its batteries to check they are
operating correctly (refer to the section on the 'Battery Test').
