Danger, Hazardous Voltage:
All work related to electrical instal-
lation to be performed by authorized personnel only (electricians
or professionals with equivalent training). The customer is
responsible for checking qualifications.
Danger, Hazardous Voltage:
Do not plug the steam humidifier
into the power grid until after all installation work has been com-
pleted.
All wiring must confirm to CEC, NEC and local electrical codes.
Warning:
The electronic components of the humidifier control
are very sensitive to electrostatic discharges. In order to protect
these components during any type of installation, steps must be
taken to guard against damage from electrostatic discharge
(ESD protection).
Warning:
For electrical installation, note the following:
•
Disconnect power supply before installation and protect
against restart.
•
Verify the absence of electric current.
•
Make sure the unit is switched off before installing or
removing the display plate or basic PCB.
•
Professionally lay electrical connector cable.
•
Install the electrical connections according to the wiring
diagram.
•
For units with rated power over 33 kW, only a perma-
nent connection to a permanent wire is allowable (Ger-
man Association for Electrical, Electronic & Information
Technologies [VDE] Standard 0700 Section 98).
•
Verify that all terminals have been tightened.
