"Explosion proof Apparatus: Apparatus enclosed in a case
that is capable of withstanding an explosion of specified
gas or vapor that may occur within it and of preventing the
ignition of a specified gas or vapor surrounding the
enclosure by sparks, flashes or explosion of the gas or
vapor within, and that a surrounding flammable atmosphere
will not be ignited thereby. "

Intrinsically Safe
"Intrinsically Safe System: An assembly of interconnected
intrinsically safe apparatus, associated apparatus, and
interconnecting cables, in that those parts of the system
that may be used in hazardous(classified) locations are
intrinsically safe circuits."

Installation Notes (#3, #4, #5, #6, #7)
#3 Dual NPT Fitting
Once lead-wire routing is determined, install enclosed NPT plug in the remaining hole.
The use of a thread locking compound (e.g. Loctite® Threadlocker Red 271™) is
recommended for securing the plug permanently.
Note:
The enclosed NPT plug must be installed in the remaining hole (unless both NPT
ports are used by conduit). Alternatively, a security NPT locking plug may be used for
non-permanent closure of the port (used by utility companies, manufacturers include:
Highfield and Inner-Tite).
#4 Wire Twisting Note
For installations where the switch module must be spun, wrenched on to a stationary
conduit and the lead-ends cannot freely rotate within the conduit: Counter-rotate the
leads before threading the switch module to the conduit. Approximately six revolutions
from the start of thread should allow the fitting to be tightened. FAILURE TO
PROTECT THE LEADS FROM TENSION OR TWIST CAN CAUSE FATAL DAMAGE
TO THE SWITCH MODULE.
#5 Intrinsically Safe Barrier
must be installed in
order to meet Intrinsic Safety Requirements
#6
Refer to figure 1-1 for completed installation.
#7
Magnasphere L2X Series is a Simple Apparatus; when used with an Intrinsically safe
Barrier, will meet or exceed the requirements for certain hazardous locations.
