Wiring
Caution:
HART versions of the PULSAR Model R96 transmitter operate at voltages of 11–36 VDC. F
OUNDATION fieldbus ™ versions operate at 9–17.5 VDC. Higher voltages will damage the transmitter.
Wiring connections between the power supply and the
PULSAR Model R96 Radar Transmitter should be made using 18–22 AWG (0.5
–1mm
2
) shielded twisted pair instrument cable. Connections are made to the terminal strip and the ground connections within the top enclosure compartment.
The directions for wiring the PULSAR Model R96 transmitter depend on the application:
• General Purpose or Non-Incendive (Cl I, Div. 2)
• Intrinsically Safe
• Explosion Proof

WARNING!
Explosion hazard. Do not disconnect equipment unless power has been switched off or the area is known to be non-hazardous.
To avoid moisture ingress in the housing, covers should be fully tightened at all times. For the same reason, cable gland and plugs should be properly installed in the cable entries.
2.5.1 General Purpose or Non-incendive (Cl I, Div. 2)
A general purpose installation does not have flammable media present.
Areas rated Non-Incendive (Cl I, Div. 2) have flammable media present only under abnormal conditions.
No special electrical connections are required.
Caution:
If flammable media is contained in the vessel, the transmitter must be installed per Class I, Div 1 standards of area classification.
To install General Purpose or Non-Incendive wiring:
1. Remove the cover from the wiring compartment of the transmitter. Install the conduit plug in the unused opening and use PTFE tape/sealant to ensure a liquid-tight connection.
2. Install a conduit fitting and pull the supply wires.
3. Connect shield to an earth ground at power supply.
4. Connect an earth ground wire to the nearest green ground screw (not shown in illustration).
