Chapter 1. Installation
1.6 Mounting the XMT868i Electronics Enclosure
The standard model XMT868i electronics package is housed in a Type-4X weather-resistant enclosure suitable for
indoor or outdoor use. Refer to
Figure 8 on page 21 for the mounting dimensions and the weight of this enclosure.
The Model XMT868i electronics enclosure is fitted with a mounting boss that has a single 3/4” NPTF threaded hole at
its center and four 1/4-20 tapped holes at its corners. By using this mounting boss, the electronics enclosure may be
mounted by any of the typical techniques shown in
Figure 9 on page 22 .
1.7 Making Electrical Connections
This section contains instructions for making all the necessary electrical connections to the Model XMT868i flow
transmitter. Refer to
Figure 10 on page 23 for a complete wiring diagram.
Except for the power connector, all electrical connectors are stored on their terminal blocks during shipment and may
be removed for more convenient wiring. Simply, feed the cables through the conduit holes on the side of the enclosure,
attach the wires to the appropriate connectors and plug the connectors back into their terminal blocks.
Refer to Figure 3 on page 6 and prepare the Model XMT868i for wiring by completing the following steps:
1. Disconnect any previously wired power line from the unit.
2. Loosen the set screw on the rear cover.
3. Place a rod or long screwdriver across the cover in the slots provided, and rotate the cover counterclockwise
until it comes free from the enclosure.
4. Install any required cable glands in the appropriate conduit holes around the side of the enclosure.
5. Note the labels inside the rear cover to assist in wiring the power and option card connections. Also, Figure 11
on page 24 shows the rear cover option card labels for every available option card configuration.
Proceed to the appropriate section of this chapter to make the desired wiring connections.
WARNING!
Proper grounding of the XMT868i chassis is required to prevent the possibility of
electric shock. See Figure 9 on page 22 to locate the chassis grounding screw.
WARNING!
To meet CE Mark requirements, all cables must be installed as described in
Appendix A, CE Mark Compliance .
WARNING!
Always disconnect the line power from the Model XMT868i before removing either
the front cover or the rear cover. This is especially important in a hazardous environment.
CAUTION!
To ensure safe and reliable operation of the flow meter, be sure to install and tighten
all cable glands in accordance with the gland manufacturer’s instructions.
