2.5 Wiring
Caution: All HART versions of the Eclipse Model 705 transmitter
operate at voltages of 11–36 VDC. Higher voltage will
damage the transmitter.
Wiring between the power supply and the Eclipse
transmitter should be made using 18–22 AWG shielded
twisted pair instrument cable. Within the transmitter
enclosure, connections are made to the terminal strip
and the ground connections. The directions for wiring
the Eclipse 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.
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 trans-
mitter must be installed per Cl I, Div. 1 standards of area
classification.
To install General Purpose or Non-Incendive wiring:
(+) 1. Remove the cover to the wiring compartment of the trans-
(-)
mitter. Install the conduit plug in the unused opening.
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).
5. Connect the positive supply wire to the (+) terminal and
the negative supply wire to the (-) terminal.
6. Replace the cover to the wiring compartment of the
transmitter.
