3. INSTALLATION
3.1. Important safety instructions
As a device with class l protection against electric shocks, it is essential to install a protective
earth wire (connect earth ). Connect the protection earth wire to the terminal (X5) before
connecting the grid to the electronic load input.
All the electrical connections, including those for control (interface, remote control…etc.), shall
be done with all the switches in OFF position and with the mains supply disconnected (thermal-
magnetic circuit breaker in OFF position too).
It must never be forgotten that the EL is a power converter, so users must take all
necessary precautions against direct or indirect contact.
Warning labels should be placed on all primary power switches installed in places far from the
device to alert the electrical maintenance personnel of the presence of a voltage in the circuit
up to 10 minutes after stopping the device.
In devices without isolation transformer, precautions must be taken as they are not
isolated from the alternating input line, and there might be dangerous voltage
between the output phases and the ground.
