Wiring Intrinsically Safe Barriers
CAUTION
If the sensor is located in a hazardous
environment, do not make any electrical
connections without first disconnecting
electrical power at the source. Ensure that
wiring connections conform to electrical
codes for the specific location and hazard
level. Refer to Installation Drawing
E0240200 on page 9 for product specific
information.
Select either a single or dual channel barrier complying
with the requirements called out in Installation Drawing
E0240200 on page 9.
Single channel barrier can only be used if the meter
(resistive load) is placed in the positive end of the loop
and the meter has a differential input.
If the meter (resistive load) must have one side
connected to ground, then a dual channel barrier must
be used.
See drawing E0240200 on page 9
for installation wiring.
NOTE:
Electrically insulate the Program Input wire during normal operation
to prevent inadvertent setting of the zero or the span points
.
