The common alarm provides a form C contact, rated at 277 V,
max 3 A.
The alarm relay is configured as Fail Safe.
The NO (normally open) contact is open in non-energized
condition. When energized, it closes during normal conditions
and will open upon an alarm condition or power failure.
The NC (normally closed) contact is closed in non-energized
condition. When energized, it opens during normal conditions
and will close upon an alarm condition or power failure.

Each nVent RAYCHEM NGC-40-PTM mounts on a DIN 35 rail.
MOUNTING: Insert the rear bottom of the module into the DIN rail, then push up and
inwards to engage the clip.
REMOVAL: Push the module upwards to
disengage the clip, then rotate the module
toward you.

The CAN termination device must be installed in the unused port of
the last module.
1. Provide suitable panel enclosure
The RAYCHEM NGC-40-IO 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

Note: The NGC-40-IO 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-IO assembly in the electrical panel.
The NGC-40-IO should be located in the rear of the panel. The NGC-40-IO
assembly is an electronic unit and must not be located where it will be
exposed to strong magnetic fields or excessive vibration.
*North American panel installation techniques
The NGC-40-IO contains no user serviceable parts. Contact your
nVent representative for service and an RMA number if required.
