Installation
Mount the relay in the panel before attaching the dust-protection assembly. The
photo shows the housing attached to a relay before the cover is applied.
Step 1. Remove the four rear-panel screws (shown in the photo) from the
back of the relay.
Step 2. Detach the dust-protection cover from the dust-protection
assembly by removing the six lid screws.
Step 3. Align the dust-protection housing and attached dust-cowling
extrusion gasket to the relay back panel.
The dust-cowling extrusion gasket creates an effective dust seal
between the relay and the housing.
Step 4. Attach the housing to the relay using the four rear-panel screws
from Step 1.
Step 5. After completing the relay rear-panel connections required for the
application, exit the housing by guiding the cables and wires
through the dust-seal foam block as shown in the photo.
Step 6. Attach the dust-protection cover to the housing with the six screws
saved from Step 2.
The dust-cowling lid gasket, which is attached to the cover, creates
an effective dust seal between the housing and the cover.
