Refer to the specifications for the specific module for power consumption and other requirements.
See XM Power Supply Solutions application technique, publication ICM-AP005A-EN-E, for additional details.
Interconnect Limit
Total current draw through the side connector cannot exceed 3A. A separate power connection is necessary if the total current draw of the interconnecting modules is greater than 3A.
If the total current draw for a row of modules is greater than 3A, consider connecting power to a module near the center of the rail, rather than at a module on either end. Insure that there is less than 3A load in either direction from the module where power is connected.
Wiring Requirements
Use solid or stranded wire. All XM wiring should meet the following specifications:
Publication
GMSI10-IN017A-EN-P - May 2010

8 XM-946 EODS Relay Terminal Base
ATTENTION
• 14 to 22 AWG copper conductors without pretreatment; 8 AWG required for grounding the DIN rail for electromagnetic interference (emi) purposes
• Recommended strip length 8 millimeters (0.31 inches)
• Minimum insulation rating of 300V
• Soldering the conductor is forbidden
• Wire ferrules can be used with stranded conductors; copper ferrules recommended
See the XM Documentation and Configuration Utility CD for Hazardous Locations installation drawings. The XM Documentation and Configuration Utility CD is packaged with the XM modules.
Grounding Requirements
Use these grounding requirements to ensure safe electrical operating circumstances, and to help avoid potential emi and ground noise that can cause unfavorable operating conditions for your XM system.
DIN Rail Grounding
The XM modules make a chassis ground connection through the DIN rail. The DIN rail must be connected to a ground bus or grounding electrode conductor using 8 AWG or 1 inch copper braid. See illustration on the following page.
Use zinc-plated, yellow-chromated steel DIN rail (Allen-Bradley part no. 199-DR1 or 199-DR4) or equivalent to assure proper grounding. Using other DIN rail materials (e.g. aluminum, plastic, etc.), which can corrode, oxidize, or are poor conductors can result in improper or intermittent platform grounding.

DIN Rail Grounding Block
24V Common Grounding
24V to the XM module must be grounded. When two or more power supplies power the XM system, ground the 24 V Commons at a single point, such as the ground bus bar.
If it is not possible or practical to ground the -24Vdc supply, then it is possible for the system to be installed and operate ungrounded. However, if installed ungrounded then the system must not be connected to a ground through any other circuit unless that circuit is isolated externally. Connecting a floating system to a non-isolated ground could result in damage to the XM module(s) and/or any connected device. Also, operating the system without a ground may result in the system not performing to the published specifications regards measurement accuracy and communications speed, distance or reliability.
The 24V Common and Signal Common terminals are internally connected. They are isolated from the Chassis terminals unless they are connected to ground as described in this manual. See Wiring on assignments.

ATTENTION
To Ground Bus
Transducer Grounding
Make certain the transducers are electrically isolated from earth ground. Cable shields must be grounded at one end of the cable, and the other end left floating or not connected. It is recommended that where possible, the cable shield be grounded at the XM terminal base (Chassis terminal) and not at the transducer.
DeviceNet Grounding
The DeviceNet network is functionally isolated and must be referenced to earth ground at a single point. XM modules can not be used with an external DeviceNet power supply. Connect DeviceNet V- to earth ground at one of the XM modules, as shown in the illustration below.
Grounded DeviceNet V- at XM Module
Use of a separate DeviceNet power supply is not permitted. See Application Technique “XM Power Supply Solutions”, publication ICM-AP005A-EN-E, for guidance in using XM with other DeviceNet products.
For more information on the DeviceNet installation, refer to the ODVA Planning and Installation Manual - DeviceNet Cable System, which is available on the ODVA web site (http://www.odva.org).

ATTENTION
Position terminal base at a slight angle and hook over the top of the DIN rail.
Switch Input Grounding
The Switch Input circuits are functionally isolated from other circuits. It is recommended that the Switch RTN signal be grounded at a single point. Connect the Switch RTN signal to the XM terminal base (Chassis terminal) or directly to the DIN rail, or ground the signal at the switch or other equipment that is wired to the switch.
Mounting on the DIN Rail
You can also mount the terminal base to a grounded mounting plate. Refer to the XM Module User Guide for details.
The XM-946 makes a chassis ground connection through the DIN rail. Use zinc plated, yellow chromated steel DIN rail to assure proper grounding. Using other DIN rail materials (e.g. aluminum, plastic, etc.) which can corrode, oxidize or are poor conductors can result in improper or intermittent platform grounding.
1. Position the terminal base unit on the 35 x 7.5mm DIN rail (A) (A-B pt no. 199-DR1 or 199-DR4) at a slight angle.

2. Slide the terminal base unit over leaving room for the side connector (B).
3. Hook the lip on the rear of the terminal base onto the top of the DIN rail, and rotate the terminal base onto the rail.
4. Press down on the ter minal base unit to lock the terminal base on the DIN rail. If the terminal base does not lock into place, use a screwdriver or similar device to open the locking tab, press down on the terminal base until flush with the DIN rail and release the locking tab to lock the base in place.
5. Connect the wiring for the XM-946 terminal base unit as shown

3. Slide the terminal base unit over tight against the neighboring terminal base. Make sure the hook on the terminal base slides under the edge of the terminal base unit.
4. Press down on the ter minal base unit to lock the terminal base on the DIN rail. If the terminal base does not lock into place, use a screwdriver or similar device to open the locking tab, press down on the terminal base until flush with the DIN rail and release the locking tab to lock the base in place.
5. Gently push the side connector into the side of the neighboring terminal base to complete the backplane connection.

Do not disconnect connections to this equipment unless power has been removed or the area is known to be nonhazardous. Secure any external connections that mate to this equipment by using screws, sliding latches, threaded connectors, or other means provided with this product.
The terminal block assignments are different for different terminal base units. The following table applies only to the XM-946. Refer to the installation instructions for the specific terminal base unit for its terminal assignments.
The primary 24V dc needs to be wired to terminal 0 to provide power to XM-946 and other XM modules located on the DIN rail. Terminal 3 should be used if a second, or redundant, power supply is needed. Note that terminal 3 provides redundant power only to the XM-946. It does not serve other terminal base units.
