Input Connections 2.3
In general, all wiring connections are made to the instrument after it is installed.
Avoid
electrical shock. AC power wiring must not be connected to the source distribution
panel until all wiring connection procedures are completed.
2.3.1 INPUT CONNECTIONS
FIGURE 2-5
AC Power
Connect 115 VAC hot and neutral to terminals B and A respectively as illustrated below.
Connect 230 VAC as described below. Connect Earth ground to the ground screw as shown.
FIGURE 2-6
Thermocouple (T/C) Input
Make thermocouple connections as illustrated below. Connect the positive leg of the thermo-
couple to terminal 3, and the negative to terminal 1. For industrial environments with com-
paratively high electrical noise levels, shielded thermocouples and extension wire are recom-
mended. Be sure that the input conditioning jumpers are properly positioned for a thermo-
couple input. See Appendix A-2 (page 65) and A-3 (page 66 and 67).
