6 Transmitter wiring

Where:

L =  Line length in meters

R =  Total resistance in Ω (ohms)

C =  Line capacitance in pF/m

Cf = Maximum internal capacitance of the HART field devices 

located in the circuit, in pF

Avoid routing cables with other electrical cables (with inductive 
load, etc.) or near large electrical equipment.

6.4 Wiring procedure

Follow these steps to wire the transmitter:

— Remove the temporary plastic cap from one of the two 

electrical connection ports located at both sides in the 
upper part of the transmitter housing.

— These connection ports may have a 1/2 inch internal 

NPT-F or M20 threads. Various adaptors and bushings 
can be fitted to these threads to comply with plant wiring 
(conduit) standards.

— Remove the housing cover of the “field terminals” side. 

See the indication on housing. In an Explosion-Proof/
Flame-Proof installation, do not remove the transmitter 
covers when power is applied to the unit.

— Run the cable through the cable gland and the open port.

— Connect the positive lead to the + terminal, and the 

negative lead to the – terminal.

— Plug and seal the electrical ports. Make sure that when 

the installation has been completed, the electrical ports 
are properly sealed against entry of rain and/or corrosive 
vapors and gases.

6.3 Supply requirement

For signal/power connection use twisted, stranded pairs of 
wiring no 18 to 22 AWG / 0.8 to 0.35mm2 ø up to 5,000 feet 
(1500 meters). Longer loops require larger wire. 

If a shielded wire is used, the shield should be grounded only at 
one end, not both ends. In case of wiring at transmitter end, 
use the terminal located inside the housing marked with the 
appropriate sign. 

The 4 to 20 mA dc output signal and the dc power supply to 
the transmitter are carried from the same pairs of wires. 

The transmitter operates from 10.5 to 42 V DC with no load 
and is protected against reverse polarity connection 

For Ex ia and other intrinsically safe approval power supply 
must not exceed 30 V DC. 

Minimum operating voltage increase to 12.3 V DC with optional 
surge protector or to 10.8 V DC with optional conformity to 
NAMUR NE 21 (2004).

For maximum power supply voltage please refer to the top 
identification plate of the transmitter.

The actual possible line length of the electrical circuit depends 
on the total capacitance and resistance, and can be estimated 
using the following formula:

Warning - General risks.

 Cable, cable gland and unused port plug 

must be in accordance with the intended type of protection (e.g. 
intrinsically safe, explosion proof, etc.) and degree of protection 
(e.g. IP6x according to IEC EN 60529 or NEMA 4x). See also the 
addendum for “EX SAFETY” ASPECTS AND “IP” PROTECTION. In 
particular, for explosion proof installation, remove the red temporary 
plastic cap and plug the unused opening with a plug certified for 
explosion containment.

— 

If applicable, install wiring with a drip loop. Arrange the 
drip loop so the bottom is lower than the conduit 
connections and the transmitter housing.

— Before reassembling covers, the integrity of the cover 

O-rings must be checked. If damaged they must be 
replaced with an original spare part. A slight grease layer 
should be applied for proper lubrication. 

— 

Put back the housing cover, turn it to seat O-ring into the 
housing and then continue to hand tighten until the cover 
contacts the housing metal-to-metal. In Ex-d (Explosion 
Proof) installation, lock the cover rotation by turning the 
set nut (use the 2mm Allen key supplied with the 
instrument).
