All electrical wiring must enter the unit through a cable gland (not supplied).
Unit switch: when the unit is switched off, there is still high voltage inside the unit. Electric
shock may be fatal, electrical isolator must be switched off.
All work on the electrical parts must be carried out by qualified and authorized personnel.
In addition, before making any electrical connections, check that your installation has been
determined from the values in table on page 21.
Respect local regulation concerning electrical connections.
Electronic components are sensitive to electrostatic charges. When working on these
components, take appropriate measures to avoid electrostatic discharges.
Humidifier electrical compartment
Power supply: Installation of an electrical
isolator with fuse protection, or ground-
fault circuit interrupter according to local
regulations (equipment not supplied).
