Outdoor and Wash Down Installations.
Tritex ratings: The TDM/X, RDM/G actuators have been tested to IP
66. Tritex actuators are not intended for applications where the actuator
could possibly be submerged.
1. Avoid rod/shaft up installations if possible; if not possible, make
external provisions to keep rod/shaft exposure to water to a
minimum. When new, the seals are effective to IP 66 or better.
However over time, depending on the amount of side load, they
can wear and eventually allow moisture to ingress. Contact Exlar
application engineering for special options.
2. With the NPT connection option use thread sealant or Teflon tape
on the connector/conduit threads .
3. If straight metric conduit connection is used verify the connector/
fitting IP rating and verify the connector O-ring is in place.
4. If cord-grip type cable glands are used, the type with soft rubber
glands are preferred (IP 68). The firmer rubber can cause the
cable to compress over time, compromising the seal between the
gland and the cable. Cable strain reliefs should also be considered
to assure tension, bending radius or flexing of the cable over time
does not compromise the seal. Careful consideration and testing is
required when these glands are used in outdoor applications.
5. If the I connector option is used verify the connector plugs are
properly sealed and have the desired
IP rating. During installation be sure to
screw the plug all the way on to the
receptacle for proper sealing.
6. Position conduit fittings or loop cable /
flexible conduit so water does not drain
towards the conduit fitting.
7. When the wire termination cover is re-
installed verify the gasket is in place
and the surfaces of the gasket as well as the cover are free from
debris so a good seal can be achieved. If the gasket is missing,
replace it with PN 51530.
8. When re-installing the termination cover, tighten all 4 screws
evenly to be sure the cover seats flat. Tighten the screws to assure
the cover is securely held against the gasket. Caution, over
tightening can strip the threads in the enclosure. If a screw is
missing replace it with

Cap Screw, Stainless Steel)
