Plug Options
High-pressure (non-hollowed), forged steel pipe
plug permanently welded to equipment or
bracket surface. Be sure weld is clear of
threads for maximum thread engagement.
Optional Adapter available from FW Murphy:
½” NPT, High-pressure (non-hollowed), steel
pipe plug, Male x Male to be used for direct
mount to equipment with a ½” NPT threaded
pilot hole.
Wiring
The method chosen to electrically connect to the switch should be mechanically flexible to
eliminate the measurement of vibration induced from conduit and to provide a moisture barrier
as well. Although Sealtite and other flexible conduit have been used successfully, in areas of
extreme humidity or moisture Murphy recommends using an “SO” type cable along with a Div.
2 suitable rain-tight CGB Gland/Strain relief fitting. No stress should be possible on the wiring
to the terminal block. If such protection is not provided by the conduit system, some form of
stress relief must be installed.
WARNING! Certification compliance requires the use of a cable
gland and strain relief fitting.
To assure compatibility with EMI compliance standards, any signal level wiring such as
transducer or 4-20 mA wiring should use shielded cable in EMI proof conduit, separate from
any power wiring except the DC power for the EVS-2. AWG 16-26 wire can be used.
NOTE: It is strongly recommended that this cabling be installed using the
method defined in the Shipboard Cable/Cord Installation document (00-
02-0725 rev 08/2010). That document can be found by following this link
