Provide Suitable Panel Enclosure, and Determine Locations for NGC-UIT2-EX Assembly in Panel
1. Provide suitable panel enclosure
To protect its electronic components, the nVent NGC-UIT2-EX
must be mounted in a panel with a minimum IP32 (Type 1)
enclosure for non-hazardous locations. An IP54 (Type 4) or better
ATEX/IECEx enclosure is required for Hazardous locations. An
IP52 (Type 12) or better enclosure is recommended. The NGC-
UIT2-EX assembly comes with a sealing gasket and hardware to
mount the enclosure.
Note: The NGC-UIT2-EX is designed for operation in ambient
temperatures from –40°C to 60°C (–40°F to 140°F). If the ambient
temperature is outside this range, a space heater and/or cooling
fan will be required in the panel.
2. Determine locations for the NGC-UIT2-EX assembly in the
electrical panel
The NGC-UIT2-EX should be located on the front of the panel near
eye level (for convenient viewing). The NGC-UIT2-EX assembly is
an electronic unit and must not be located where it will be exposed
to strong magnetic fields or excessive vibration.
Conditions of Safe Use
This equipment must be installed in a hazardous location
classified cabinet or panel rated as follows:
• Internal and external ambient of: -40ºC to +60ºC
• Minimum ingress protection rating of IP54
• ATEX / IECEx: Zone 2 or better
• US / CAN: Class I Div 2 or better
• Can only be opened with the use of a tool
Do not connect/disconnect equipment unless power has
been switched off or the area is known to be non-hazardous.
Ne débranchez pas l'équipement que l'alimentation est
coupée ou que la zone est connue pour être non dangereux.
• Use appropriately classified Limited Power Source, or
LPS. Follow all applicable wiring codes and regulations.
• Peripheral equipment must be suitable for the location in
which it is used.
There are no non-incendive circuits or non-incendive field
wiring within or associated with the unit.
