Installation and User's manual
Powering down the EXL 1000 for long periods is not
recommended because the battery should remain charged.
However, to carry out a power down, proceed as follows:
• Shutdown the inverter (section 3.5)
• Put the battery circuit breaker in the "off" position;
• Turn off the input circuit breaker
All the LEDs on the control panel will go off.
WARNING
• Put the upstream circuit breaker(s) on the low voltage
switchboard in "off" position.
The AC input power supply is present:
the green "load protected" light (figure 3-13) is on;
the power drawn by the load is supplied by AC input power
via the rectifier and inverter modules. The battery charger
float charges or recharges the battery.
voltage of the battery charger is temperature regulated to
ensure an optimal charge voltage.
