HOW TO RECOGNIZE PHASE AND NEUTRAL
WARNING!
Take GREAT CARE when testing anything with live current and always use your personal protective
equipment; if you are unsure what you are doing and how to use your equipment safely then DON'T
DO IT
The appliance is equipped with a power cord and socket, however, in case of need , some basic tips on how
to check the supply wires before our main terminal board.
Double zone appliances are three phase supplied : L1+L2+L3 +N
Single zone is single phase supplied: L+N
Put your meter in AC Volts setting. Connect supply to the main terminal board MA but do not turn on the ap-
pliance. Connect the meter test leads to the terminal board contacts; the readings should be:
L1 / L2 / L3 + N* (Phase and Neutral) = 230 Volts
(+/- 6% based on European standards)
L1 / L2 / L3 +
(Phase and Earth) = 230 Volts
L1 and/or L2 + L3 (Phase and Phase) = 400 Volts
N +
(Neutral and Earth) = 0 Volts
(or approx. zero V)
The combination and results obtained will permit you
to find all wires: PHASE, NEUTRAL and EARTH.
RESIDUAL CURRENT
The contact opening max. distance and leakage current must comply with the local safety regulations.
Many countries use a 30mA, but you must refer to the local regulations!!
