Environmental Seals
The NRD1 enclosure is rated IP-67.
To maintain this rating, the installer
must pay special attention to the
environmental seals:
NRD1 Manual - PRELIMINARY
Front Plate Gasket
This is this primary seal of the
enclosure. It fits around the entire
face of the housing.
The front plate sits on the silicon
gasket as shown to the left. The
front plate must be properly alighed
with the H-shape gasket prior to
clamping with the front plate screws.
The gasket should be wiped clean
with water prior to installation. No
alcohol or solvents should be used
on the gasket as it will degrade the
material.
Cable Gland
The cable gland is the seal for the
entry of the power cable. The cable
must be fed through the nut and the
gland. Once the cable is in place,
the nut can be tightened until a
complete seal is present.
