2.5.2 Intrinsically Safe
An Intrinsically Safe (IS) installation potentially has flam-
mable media present. An approved IS barrier must be
installed in the non-hazardous (safe) area to limit the avail-
able energy out to the hazardous area.
See Agency Drawing – Intrinsically Safe Installation,
Section 3.5.2.

1. Remove the cover of the Model 700 transmitter.
2. Using the grip edge at 3 o’clock and 9 o’clock on the LCD
module shown at left, carefully remove the LCD module
from the transmitter. (Note that this module is conve-
niently tethered to the device.)
3. Attach a conduit fitting and mount the conduit plug in
the spare opening. Pull power supply wire through the fit-
ting.
4. If present, connect cable shield to an earth ground at the
power supply.
5. Connect an earth ground to the green ground screw (Not
shown in illustration).
6. Connect the positive supply wire to the (+) terminal and
the negative supply wire to the (-) terminal.

insert the LCD assembly; replace and tighten the cover.
