1. Provide suitable panel enclosure
The NGC-40-BRIDGE must be mounted in an enclosure
to protect its electronic components. For indoor
applications, use a minimum NEMA 1 enclosure (NEMA 12
recommended). For outdoor applications, use a NEMA 4 or
NEMA 4X enclosure depending on the requirements.
Note:
The RAYCHEM NGC-40-BRIDGE is designed for
operation in ambient temperatures from –40°C to 65°C
(–40°F to 149°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-40-BRIDGE assembly in
the electrical panel.
The NGC-40-BRIDGE should be located in the rear of the
panel. The NGC-40-BRIDGE assembly is an electronic unit
and must not be located where it will be exposed to strong
magnetic fields or excessive vibration.
