Installing Unit Supplied with External Power Option

Refer to figure 6 when installing the wiring.

1. Loosen the two instrument screws and open the cover.

WARNING

Select a cable gland that is rated for the environment of use (such as hazardous area, ingress protection and temperature).

Failure to use properly rated cable glands can result in personal injury or property damage from fire or explosion.

When installing the cable gland or conduit fitting minimize the amount of wires remaining in the housing cavity so they do

not get compressed or damaged when closing the cover in step 7.

2. Insert a user-supplied cable gland or conduit fitting into the housing.

3. Insert the wires through the cable gland/conduit fitting.

4. Connect the wires to the connections as shown in figure 6. The terminals and electronics connections are

polarity-insensitive; ie., you can connect the positive or negative wire to either terminal screw.

5. As shown in figure 6, a ground terminal is available for connecting a safety ground. Make connections to this

terminal following national and local codes and plant standards.

6. Tighten the wiring terminal screws.

7. Close the cover and tighten the instrument cover screws to a torque of 5.6 to 6.7 N•m (50 to 60 lbf•in).
