XM-940 Dynamic Measurement Terminal Base 7 WARNING • This equipment shall be mounted in an ATEX-certified enclosure with a minimum ingress protection rating of at least IP54 (as defined in IEC 60529) and used in an environment of not more than Pollution Degree 2 (as defined in IEC 60664-1) when applied in Zone 2 environments. The enclosure must have a tool-removable cover or door.
XM-940 Dynamic Measurement Terminal Base IMPORTANT There are no drawings associated with the XM-124 Standard Dynamic Measurement Module, catalog number 1440-SDM02-01RA. Be sure that the installer follows all applicable local and regional requirements for installation of the product in the planned location and environment. Power Requirements Refer to the XM-124 Standard Dynamic Measurement installation guide, publication 1440-IN001, for specific power consumption and other requirements.
XM-940 Dynamic Measurement Terminal Base 9 Wiring Requirements Use solid or stranded wire. All XM wiring should meet the following specifications: • 0.34…2.1 mm2 (22…14 AWG) copper conductors without pretreatment; 8.4 mm2 (8 AWG) required for grounding the DIN rail for electromagnetic interference (EMI) purposes • Recommended strip length 8 mm (0.31 in.

XM-940 Dynamic Measurement Terminal Base 11 The grounding wire can be connected to the DIN rail by using a DIN Rail Grounding Block (see illustration below). DIN Rail Grounding Block 1 1 Use 8.4 mm2 (8 AWG) wire. 24V Common Grounding 24V to the XM module must be grounded. When two or more power supplies power the XM system, ground the 24V Commons at a single point, such as the ground bus bar.
XM-940 Dynamic Measurement Terminal Base IMPORTANT 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 page 17 for terminal assignments. 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.
XM-940 Dynamic Measurement Terminal Base 13 DeviceNet Grounding - XM-124 Module Only The DeviceNet network is fully isolated from the XM-124 power and ground circuits. Therefore, DeviceNet network can be powered from any suitable DeviceNet power supply, and must be grounded at that power supply in accordance with DeviceNet installation instructions. Switch Input Grounding The Switch Input circuits are functionally isolated from other circuits.
XM-940 Dynamic Measurement Terminal Base Mounting on the DIN Rail You can also mount the terminal base to a grounded mounting plate. Refer to the XM-124 Standard Dynamic Measurement Module User Manual, publication 1440-UM001. 1. Position the terminal base unit on the 35 x 7.5mm DIN rail (A) (Allen-Bradley pt no. 199-DR1 or 199-DR4) at a slight angle. Position terminal base at a slight angle and hook over the top of the DIN rail. 2.
XM-940 Dynamic Measurement Terminal Base 15 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 terminal 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.
XM-940 Dynamic Measurement Terminal Base Interconnecting Terminal Base Units Follow the steps below to install another terminal base unit. IMPORTANT Terminal base units are mounted left to right on the DIN rail. 1. Position the terminal base on the 35 x 7.5mm DIN rail (A). 2. Make certain the side connector (B) is fully retracted into the base unit. 3. Slide the terminal base unit over tight against the neighboring terminal base.
XM-940 Dynamic Measurement Terminal Base 17 Wiring IMPORTANT For more wiring connection information, refer to the XM-124 Standard Dynamic Measurement Module User Manual, publication 1440-UM001. Terminal Assignments WARNING ATTENTION If you connect or disconnect wiring while the field-side power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.
