Detcon X40-32-N7 - Manual (Page 29)

Model X40
Model X40 Instruction Manual Rev. 3.3 Page 23 of 64
NOTE
Proper electrical installation of the wireless radio module assembly is critical for
conformance to Electrical Codes and to avoid damage due to water leakage. A conduit seal
is typically required to be located within 18" of the transceiver assembly if a conduit run is
required. Crouse Hinds type EYS2, EYD2 or equivalent are suitable for this purpose.
NOTE
Any unused ports should be blocked with suitable
3
/
4
" male NPT plugs. Detcon supplies one
3 /
4
" NPT male plug with each J-box enclosure. If connections are other than 3 /
4
" NPT, use
an appropriate male plug of like construction material.
NOTE
Use suitable cord connectors (cable glands) for cable entry to the X40 controller or the
connecting Junction Box.
NOTE
The Detcon Warranty does not cover water damage resulting from water leaking into the
enclosure.
5. If the unit comes with an AC/DC Adapter, ensure that the AC signal/wiring is not housed in the
same conduit as the DC signal/wiring.
