1.0 GENERAL NOTES
1.1 For Class II, Class III (Division 1 and 2) and NEMA/CSA
type 4X installations, use conduit hub which is listed/certified
for the environment in which the indicator is installed.
1.2 For Class II and III (Division 1 and 2) installations, field wiring
must enter the enclosure through a listed/certified dust-tight
conduit seal.
1.3 Control room equipment must not use or generate more than
250 VRMS or VDC.
1.4 US installations must be in accordance with ANSI/ISA
RP12.06.01 "Installation of Intrinsically Safe Systems for
Hazardous (Classified) Locations" and the National Electrical
Code (ANSI/NFPA 70). Canadian installations must be in
accordance with the Canadian Electrical Code, Part 1.
1.5 Hazardous location installation instructions for associated
apparatus (barrier) must also be followed when installing this
equipment.
1.6 For safe installation of a FM Approved/CSA Certified
transmitter in series with RD100 loop indicator, the hazardous
location installation instructions for the transmitter, RD100 loop
indicator, and associated apparatus (barrier) must be compatible.
1.7 RD100 indicator does not add capacitance or inductance to loop
under normal or fault conditions.
1.8 Substitution of components may impair hazardous location
safety.
2.0 RD100 CONDUIT INSTALLATION INSTRUCTIONS
2.1 Remove the Display from the enclosure and connect ½" conduit
fittings to the hole provided. For enclosures without a
pre-drilled hole, the installer must make a hole in accordance
with the instructions for the particular conduit fitting being
installed.
2.2 Use only UL/CSA conduit hubs that are specified to maintain
NEMA 4X and Class II / Class III ratings.
2.3 Conduit hubs must be connected to the conduit prior to being
connected to the enclosure.
2.4 Enclosure must be mounted using the mounting holes located in
the base external to the equipment cavity.

Using single or dual channel intrinsic safety barrier
Application Notes:
3.1 U i > U o of single channel barrier or V t of dual channel
barrier
3.2 I i > I o of single channel barrier or I t of dual channel barrier
3.3 L i plus interconnecting wiring < L o of single or dual channel
barrier
3.4 C i plus interconnecting wiring < C o of single or dual channel
barrier
3.5 It is not necessary to use intrinsic safety barriers when installing
the RD100 in Class I,II,III, Division 2, Groups ABCDFG,
maximum input voltage = 30 VDC.

Application Notes:
4.1 Barrier parameters must meet the following requirements:
V oc or U o ≤ V max or U i
I sc or I o ≤ I max or I i
C a or C o ≥ C + C cable
i
L a or L o ≥ L i + L cable
P o < P i
4.2 For CSA Certification, barrier and transmitter must be CSA
Certified with Entity Parameters and must be connected per
manufacturer's instructions.
