ELECTRICAL CONNECTIONS
All works concerned with electrical installation must be carried out by a skilled and
qualified personnel.
Make sure that all incoming power supplies are isolated before installation and
maintenance of the ElectroVap MC2 humidifier.

WARNING :
Failure to fit an electrical power isolator and MCB as
part of the electrical installation significantly increases

The symbol ∆ between Q1 & Q2 means that
these MCB are coupled. The power MCB Q2
and control MCB Q1 are mechanically linked
together. So if a fault is detected, the power and
the control circuits are switched off and there is
no voltage on the unit. The unit is really off
voltage.
D) 3 phases without neutral: 3 x 380-400 V
In this case, a transformer (option) must be ins-
talled (See technical notice page n°33)
