Installation

19

Note: 

Primary components may 

become hot under high line voltage 
and ambient temperature 
conditions. ac wiring insulation must 
be rated a minimum of 95 °C. 

6.

Tighten the connectors using a small flat-head screwdriver. Firmly tug on 
each wire to ensure solid connections.

7.

Reinstall the shielding plate and front cover if all of the wiring is complete. 

8.

See 

section 5.2 on page 26

 for information on setting alarms.

4.4.5 Analog and RS485 Output Connections

This transmitter is designed for either a 4–20 or 0–20 mA output with a maximum 
800 ohm load. Make output connections with twisted-pair shielded wire. Connect 
the shield at the recorder or controlled component end only. On the opposite end, 
remove the shield and insulate the remaining wires.

Note: 

The RS485 card is factory 

installed, it does not need to be 
re-installed.

1.

Remotely disconnect all instrument power before opening the analyzer door.

2.

Remove the front cover.

3.

Strip the insulation on the outer jacket back 7 inches. Remove the conductors 
from the shield. 

4.

Cut the shield to 1 inch. Connect it to the ground on the shielding plate.

Note: 

Use a twisted-pair, shielded 

cable. Use of non-shielded cable 
may result in radio frequency 
emission or susceptibility levels 
higher than allowed.

5.

Strip the insulation on the remaining wires back ¼-inch.

6.

Route the wire through the front left conduit opening. Use the provided 
cord-connected strain reliefs to ensure adequate sealing. Use appropriate 
NEMA sealing hardware.

7.

Insert the wire ends into the Analog or RS485 connector until the insulation 
seats against the connector. Refer to 

4.5

 and 

Table 1 on page 21

.

8.

Tighten the connectors using a small flat-head screwdriver. Firmly tug on 
each wire to assure solid connections.

9.

Reinstall the shielding plate and front cover if all of the wiring is complete.
