Electrical Connections

CAUTION: Risk of electric shock. Disconnect the humidifier from the electric
supply before proceeding with the connection.
WARNING: Risk of fire. Do not interchange the power terminal block designated
L1, L2 and L3 with low voltage terminal block designated 1, 2 and 3.
The wiring to the humidifier must be done by a qualified electrician and must conform to
the procedure, regulation and local codes.
Use copper conductors only.
The humidifier is equipped with a built-in disconnect switch, to turn off the power without
opening any access doors.
An external over current protection must be installed on the supply, adjacent to the
humidifier. It is also recommended to install a circuit breaker.
To provide strain relief to the supply cable, install a knock-out (not supplied) at the bottom
of the electrical compartment of the humidifier.
Ensure that the size of the wire conductors is appropriate for the current supplied.
Ensure that each terminal connection is properly secured.
Ensure that the ground conductor is equipped with a ring terminal and is connected
directly to the electrical panel.
