Outdoor and Wash Down Installations
Tritex ratings: The T2M 090/ 115 with the P5 option and the T2X
90/115, R2M/G 090/115 have been tested to IP 65. The electronic
enclosure as tested by UL as a Type 4 enclosure rating if NPT
connection ports are used. 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 65 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. If possible, position conduit fittings or
loop cable / flexible conduit so water
does not drain towards the conduit
fitting. When the wire termination
cover is re-installed, verify the O-ring gasket is in place and the
surfaces of the O-ring as well as the cover are free from debris
so a good seal can be achieved. If the O-ring is missing replace
it with PN – 46896
7. 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 O-ring/gasket.
Caution, over tightening can strip the threads in the enclosure. If
any screws are missing replace them with Exlar PN 64746
