Electrical connection

Do NOT make electrical connections unless the electrical code designation stamped on the transmitter data
plate agrees with the classification of the area in which the transmitter is to be installed. Failure to comply
The 4 to 20 mA output signal and the dc power supply to the transmitter are carried from the same pairs of
wires. The supply voltage at the transmitter terminals must be between the limits of 10.5 and 42V dc.
For intrinsically safe approval EEx ia supply must not exceed 30 Vdc. In some countries the maximum power
supply voltage is limited to a lower value.
Electrical shock can result in death or serious injury. Avoid contact with the leads and terminals. High voltage
Follow these steps to wire the transmitter:
1. Remove the red temporary plastic plug from one of the two electrical connection ports located at both
sides in the upper part of the transmitter housing
2. These connection ports have a ½ inch internal NPT or CM20 x 1.5 mm threads. Various adaptors and
bushings can be fitted to these threads to comply with plant wiring (conduit) standards.
3. Remove the housing cover.
In an Explosion-Proof/Flame-Proof installation, do not remove the transmitter covers when power is applied
to the unit. Remove the power supply and continue the operation
4. Run wiring through the open port
5. Connect the positive lead to the + terminal, and the negative lead to the - terminal
Note: Do not connect the power across the test terminals. Power could damage the diode in the test
Plug and seal the electrical ports. Make sure that when the installation has been completed, the electrical
ports are properly sealed against entry of water and corrosive vapors and gases.
Cables, 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 or NEMA 4x). In particular, for
explosion proof installation, plug the unused opening with a plug certified for explosion containment.
