Wiring Procedure - Honeywell SLG 700 Quick Start Manual

FOUNDATION Fieldbus Operating Ranges
The FOUNDATION Fieldbus SLG 700 transmitter requires a terminal voltage in the range
9Vdc to 32Vdc.

WIRING PROCEDURE

Step
Ensure the loop power supply is off.
1
Remove the end cap cover from the terminal block end of the Electronics
2
Housing
Insert the power leads through each conduit entrance. The transmitter
3
accepts wire thicknesses up to 16AWG.
Plug the unused conduit entrance. See section above.
4
Connect the positive loop power lead to the positive (+) terminal and the
5
negative loop power lead to the negative (-) terminal.
Replace the end cap, and secure it in place.
See Note below
6
Optional: Transmitters that comply with the ATEX 4 directive for self-
declared approval per 94/9EC or 2014/34/EU, the power supply must
7
indicate a voltage limiting device.
The transmitter has internal and external terminals to connect to the ground (earth).
While it is not necessary to ground the transmitter for proper operation, grounding the
transmitter can minimize the possible effects of noise on the output signal and
protects the housing from lightning and static discharge, and may be required to
meet various approval body certifications, for example CE conformity.
An optional terminal block with lightning protection can be installed in place of the
non-lightning protection terminal block for Transmitters that will be installed in areas
susceptible to lightning strikes.
Note: The transmitter is polarity-insensitive with respect to loop power connection.
Nevertheless, to assist with troubleshooting and maintain same installation procedure,
it is recommended to connect loop wiring as per Step 5.
