6.4 Cable Glands, Blanking Elements & Adapters
Ingress Protection
If a high IP (Ingress Protection) rating is required then a suitable
sealing washer must be fitted under the cable glands or blanking
plugs. A minimum ingress protection rating of IP6X must be
maintained for installations in explosive dust atmospheres.
To maintain the ingress protection rating and mode of protection,
the cable entries must be fitted with suitably rated cable entry
and/or blanking devices during installation.
If entries are fitted with adaptors they must be suitably rated for
the application. Fitting of blanking elements into adaptors is not
permitted.
Adapters
The GNEx sounder range can be supplied with the following types of
adapters:
M20 to ½” NPT
M20 to ¾” NPT
M20 to M25
It is important to note that stopping plugs cannot be fitted onto
adapters, only directly onto the M20 entries.
Any other adapters used must be suitably rated and certified.
If the installation is made using conduit, openings must have a sealing
fitting connected as close as practical to the wall of the enclosure, but
in no case more than the size of the conduit or 50mm, whichever is
the lesser.
