Never work on the system with the device cut in.
• Do not access the electrical connections without having powered
down the system.
• The product is not suitable for installation in phase-to-phase
networks.
• When the device is in manual mode it carries out the protection
function of a traditional differential switch.
• When the device is in automatic mode it makes a periodic function
check and makes a check of the system, following the opening of the
differential switch, to verify the possibility of restarting automatically
in safety.
• Possible intermediate positions of the lever are not malfunctions if
they are temporary.
• If the system is to be powered down manually within 3 minutes of a
previous automatic restart, use the test button of the differential
switch after opening the hatch (or use the switches connected
downstream).
• It is quite normal for the lever to click and to hear noises during the
self-diagnosis cycle
N.B. Read carefully before installing and using the device
