3.4Wiring the outputs (Zone 1 Exe and Zone 2)

Note: For wiring instructions for Zone 1 Exi transmitters, see Section 3.5.

WARNING

Hazardous voltage can cause severe injury or death.

To avoid the risk of hazardous voltage, shut off the power before wiring the transmitter outputs.

WARNING

A transmitter that has been improperly wired or installed in a hazardous area could cause an explosion.

To avoid the risk of an explosion:

•Make sure the transmitter is wired to meet or exceed local code requirements.

•Install the transmitter in an environment that complies with the classification tag on the transmitter. See Appendix A.

To wire the outputs:

1.Remove the transmitter housing cover and user interface module. See Section 2.4 for instructions.

2.Wire the outputs according to the appropriate wiring diagram:

•For mA output wiring diagrams, see Section 3.4.1.

•For frequency output wiring diagrams, see Section 3.4.2.

•For discrete output wiring diagrams, see Section 3.4.3.

•For a discrete input wiring diagram, see Section 3.4.4.

3.Replace the user interface module and transmitter housing cover.
