Mounting the NGC-40-BRIDGE
REMOVAL: Push the module upwards
to disengage the clip, then rotate the
module toward you.
Each NGC-40-BRIDGE 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.

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.

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.
