XM-941 Speed/Position Terminal Base 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. IMPORTANT IMPORTANT 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.
XM-941 Speed/Position Terminal Base 11 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-941 Speed/Position Terminal Base 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.
XM-941 Speed/Position Terminal Base 13 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 terminal base unit to lock the terminal base on the DIN rail.
XM-941 Speed/Position Terminal Base 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 terminal base unit to lock the terminal base on the DIN rail.
XM-941 Speed/Position Terminal Base 15 Terminal Assignments WARNING EXPLOSION HAZARD Do not disconnect equipment unless power has been removed or the area is known to be nonhazardous. 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.
XM-941 Speed/Position Terminal Base XM-220 Dual Speed Module Terminal Assignments No. Description No.
XM-941 Speed/Position Terminal Base 17 IMPORTANT The DeviceNet power circuit through the XM module interconnect, whichis rated at only 300mA, is not intended or designed to power DeviceNet loads. Doing so could damage the module or terminal base. To preclude this possibility, even unintentionally, it is recommended that DeviceNet V+ be left unconnected. 1 Terminals are internally connected and isolated from the Chassis terminals.
XM-941 Speed/Position Terminal Base XM-320 Position Module Terminal Assignments No. Description No.
XM-941 Speed/Position Terminal Base 19 IMPORTANT The DeviceNet power circuit through the XM module interconnect, whichis rated at only 300mA, is not intended or designed to power DeviceNet loads. Doing so could damage the module or terminal base. To preclude this possibility, even unintentionally, it is recommended that DeviceNet V+ be left unconnected.
