ENCLOSURE INSTALLATION
Locate the enclosure within 500 ft (150 m) of the sensor. It can be wall mounted with four mounting
screws (supplied) or panel mounted with Option PM Panel Mounting Kit from Greyline Instruments.
Avoid mounting the enclosure in direct sunlight to protect the electronics from damage due to
overheating and condensate. In high humidity atmospheres, or where temperatures fall below freezing,
Option TH Enclosure Heater and Thermostat is recommended. Seal conduit entries to prevent moisture
from entering enclosure.
NEMA4X (IP66) WITH CLEAR COVER
1. Open hinged enclosure cover.
2. Insert #8 screws and washers through the four enclosure
mounting holes to secure enclosure to wall or mounting stand.
3. Close cover.
Additional conduit holes can be cut in the end of the enclosure
when required. Use a hole saw or Greenlee-type hole cutter to cut
the required holes.
Note: This non-metallic enclosure does not automatically provide grounding between conduit
connections. Grounding must be provided as part of the installation. Ground in accordance with the
requirements of the National Electrical Code. System grounding is provided by connecting grounding
wires from all conduit entries to the steel mounting plate or another point which provides continuity.
