Installation and Wiring 7
2.2 Sealoff Fittings
The utmost care must be taken to completely seal the inside of the enclosure off from the outside world. To do
this all wiring into and out of the enclosure must be in conduit using sealoff fittings between the enclosure and
the conduit. The sealoff fittings ensure that the hazardous atmosphere does not travel either through the conduit
or through insulation or wiring back to the safe area. The graphic shown below illustrates the location of sealoff
fittings.
These fittings, once installed and sealed are very difficult to remove so make sure all the wiring has been double
checked before beginning. If rigid conduit is not being used for connection to the scale base, be sure to install an
approved strain relief fitting to avoid pulling the wires out of the sealoff fittings in an accident. Doing so would
open a flame path to the enclosure and defeat its purpose.
