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.
1 - Power supply isolator and MCB ( near the unit )
2 - Power supply cable
3– Electrical compartment
WARNING :
Failure to fit an electrical power isolator and MCB as
part of the electrical installation significantly increases
the risk of electric shock, which can be fatal.
Q1 and Q2: MCB and electrical power isolation
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.
ALL WORKS CONCERNED WITH ELECTRICAL INSTALLATION MUST BE CARRIED OUT BY A SKILLED AND QUALIFIED PERSONNEL
