STEP 0: The RPST-PowerVent replaces the bottom access plate in the
ENC-ST steel enclosure.
STEP 1: Remove the 8 screws from the existing access plate and re-
move the existing access plate. Remove the cable glands and hole
plugs from the existing plate.
STEP 2: Assemble cable glands and hole plugs to the RPSTPowerVent plate.
STEP 3: Install the RPST-PowerVent to the enclosure with the fan on
the left side. Tighten 8 screws loosely and then tighten to seal the gasket against the bottom of the enclosure. Don’t over tighten or plate will
be bent and gasket seal won’t work properly.
STEP 4: Route red and black wires to a 12VDC power source. Connect
red wire to V+ and black wire to V-.

TECH CORNER
Additional Information you may find useful
1. THERMOSTAT: The thermostat will turn on the fan when tempera-
ture at the thermostat reaches 50C (122F). The fan will turn off when
the temperature falls below 40C.
2. COOLING: The fan should bring the interior of the enclosure to ambient temperature within about 5 mins. If the enclosure is seeing strong
solar heating, the fan may need to run longer to compensate for the
additional heat from the sun. If there is equipment inside the enclosure

generating heat, the fan may run longer to compensate for the internal
heating.
3. FILTER MESH: The stainless steel filter mesh should be small
enough to keep out most insects but will allow dust to enter. If the unit
will be used in dusty areas, we recommend adding a dust cover over
the existing filter mesh. A square piece of filter material can be cut and
fastened over the existing filter mesh using Velcro. The unit should be
checked periodically for clogged filters and they should be cleaned if
clogged to maintain best performance. The stainless steel filter mesh
can be removed with two screws and cleaned with water.
4. FAN DIRECTION: The fan is setup to blow air towards the inside of
the enclosure. This is done to maintain a slightly higher pressure inside
the enclosure when the fan is running. This helps to reduce the humidity inside the enclosure.
5. WATER INGRESS: The RPST-PowerVent is mounted to the bottom
of the enclosure so in normal use water won’t be able to make it’s way
inside the enclosure. If mounted close to the ground or near lawn sprinklers or irrigation sprinklers it’s possible for water to enter the enclosure
through the filter mesh. Be careful about site preparation when using
the RPST-PowerVent. Do not use if the bottom of the enclosure will be
subjected to spraying water.
