Hole Plugs
Three hole plugs are supplied with the wiring base. Use these plugs on
unused conduit openings to maintain the NEMA Type 4 rating.
•
U.S. Wiring Base (Catalog No. 2755-NB40)
The conduit opening for the U.S. wiring base uses an N.P.S.C. threaded
plug. Use teflon tape or other thread sealant when inserting the hole plug
in the conduit opening to maintain a NEMA Type 4 seal. Tighten hole
plug with a 3/8” hex wrench.
•
Metric Wiring Base (Catalog No. 2755-NB41)
The conduit opening for the metric version requires an O-ring with the
hole plug. Place the O-ring on the hole plug, then insert the hole plug in
the conduit opening and tighten with a flat blade screwdriver.
Wiring Base Dust Cover
To prevent debris from entering the wiring base when a Reader is not
installed, slip the wiring base dust cover over the base. The wiring base dust
cover is held in place by the stretch fit of the cover itself.
!
ATTENTION: The wiring base dust cover is not intended for
permanent installation. The wiring base dust cover temporarily
protects the wiring base until a Reader is installed.
