5.11.1 General
Safety
The electrical installation work requires removal of the access panels in the humidier. Observe the
following safety precautions:
DANGER!
Risk of electric shock!
The Nortec GS humidier is mains powered. Live parts may be exposed when the access
panels are removed. Touching live parts may cause severe injury or even death.
Prevention: The Nortec GS humidier must be connected to the mains only after all installa-
tion work has been completed, checked for correct workmanship, and the access panels are
installed and fastened securely.
CAUTION!
Electrostatic discharge (ESD)!
The electronic components inside the humidier are sensitive to electrostatic discharge
(ESD).
Prevention: Take appropriate measures to protect the electronic components inside the unit
against damage caused by electrostatic discharge (ESD). Refer to ANSI/ESD-S20.20.
• All electrical installation work must be performed only by a licensed electrician authorized by the
customer. It is the customer’s responsibility to verify qualications of the personnel.
• The electrical installation must be performed according to the wiring diagrams in this manual,
the instructions in this section, as well as applicable national and local codes.
• Make sure that the main power cable is properly grounded through the ground lug inside the
control cabinet. When installed, the appliance must be electrically grounded in accordance with
local codes or, in the absence of local codes, with the National Electrical Code (ANSI/NFPA70)
in the USA, and/or CSA C22.1 Electrical Code in Canada.
• Field wiring from the humidistat to the humidier and between devices must be shielded minimum
18 AWG, and shall conform with temperature rise limitation of 63 °F (35 °C) for Type-T wire.
• All cables must lead into the unit, via appropriate strain relief connectors, and be secured with
clamp straps.
• Make sure the cables are secured, and do not rub on any components or become a tripping hazard.
• Adhere to national and local codes for maximum cable length and required wire sizes for cables.
