Precautions regarding accidental earth leaks
The isolation transformer PE terminal must be earthed and connected before any other terminal.
The isolation transformer must be closed before it is switched on.
People protection
AC input supply: accidental leakage current between phase and earth
Standard NFC15-100 should be followed when installing.
Use the services of an electrician or professional installer to make the necessary connections. The isolation
transformer should be connected to a system having a 30mA differential two-poles circuit-breaker.
AC output distribution: accidental leakage current between output circuit and the earth
Accidental current leakage at the earth must be detected by means of an independent protective device
outside the isolation transformer (a residual current device or an insulation detector).
The installer should decide on the rating and nature of the protection according to the risks.
Precautions regarding lightning
In areas highly exposed to lightning, it may be advisable to install a lightning arrestor upstream of the
isolation transformer to safeguard it against irreversible damage.
Precautions regarding overheating of the appliance
This appliance is designed to be mounted on a vertical wall or partition as indicated herein.
It is imperative that there be a gap of 10cm around the isolation transformer. The installer must see to it
that the temperature of the air at the input is lower than 50°C in extreme operating conditions.
Measures should also be taken to allow for the discharge of hot air on either side of the box.
It’s strictly forbidden to put any device on or against the material.
The box must not be installed near a source of heat; it should be installed in a well-ventilated area. The
box's air inlets and outlets must not be obstructed.
Be careful hot surface: do not touch the isolation transformer during and after its operation (risk of burn).
Precautions regarding dust, seepage and falling water
The isolation transformer should be located so as to prevent penetration of damp, liquid, salt and dust, any
of which could cause irreparable damage to the equipment and be potentially hazardous for the user.
The appliance should be installed in a dry and well-ventilated place.
Precautions regarding inflammable materials
The isolation transformer should not be used near inflammable materials, liquids or gases.
Other precautions
Never attempt to drill a hole in or to machine the isolation transformer : this may damage isolation function
and its electronic control board.
Do not do anything that is not explicitly stated in this manual.
