CONDUIT
When aaching conduit, observe the following:
• Avoid long runs of unsupported conduit that can transfer unwanted impacts or vibra-
on of the conduit, rather than of the machine.
• Orient conduit such that accumulated moisture or condensaon does not drain into the
switch and consider the use of J-traps or other drain mechanisms.
• Units with NPT conduit holes (ordering opon E=1, 2, 3, and 7) have ¾” NPT threads.
Units with metric conduit holes (ordering opon E=4, 6, and 8) have M20 x 1.5 threads.
Refer to datasheet 1004461 for a complete list of ordering opons.
• Use proper conduit seals meeng the environmental requirement of the installaon to
prevent ingress of moisture and dust.
WIRING
• Remove the cover and wire the switch (es) into the alarm or shutdown circuit.
• Extra care should be taken to not damage the spring mounted on the underside of the
cover. Damage to this spring could prevent the switch from being reset.
• Do not exceed switch contact rangs listed on the cover.
• Observe all local electrical codes.
• All power must be switched o before opening of the enclosure in an explosive atmo-
sphere.
• The Vibraon Switch must be electrical connected by means of a ameproof/dust cable
gland or stopping box cered to:
IEC60079-0: 2011(EN60079-0:2012), IEC60079-1: 2007(EN60079-1:2007)
and IEC60079-31: 2008(EN60079-31:2009).
• For ambient temperatures below –10°C, use eld wiring suitable for the minimum
ambient temperature.
• Reinstall the cover by rst insuring the o-ring is in place and properly seated in the
grove in the housing. Place the cover on the unit and install the four cover screws.
Torque these screws to 6-7 /lbs.
NOTE: Route internal wiring away from the moving part of
the switch mechanism and secure so that it cannot move or
loosen over me. Wiring that impedes trip plate movement
may result in a switch that does not trip properly or at all.
NOTE: The disposable plasc plugs that ship in each
conduit hole provide only physical thread protecon
during shipping and handling. They are not
designed for use as permanent hole plugs and do
not provide adequate environmental protecon
for the switch when installed in the eld.
NOTE: Do not over-torque the bolts as this could
damage the housing and compromise the seal.
