3.0 INSTALLATION
This section describes how to install and replace the Analog Rail
module. Note that analog signals are sensitive to variations in
temperature. The Analog Rail module is designed to perform
optimally at room temperature, approximately 25 o C. In all cases, the
ambient temperature of the installation must be maintained in the
range specified in Appendix A to ensure the highest possible
accuracy.
DANGER
THE USER IS RESPONSIBLE FOR CONFORMING WITH THE NATIONAL
ELECTRICAL CODE AND ALL OTHER APPLICABLE LOCAL CODES. WIRING
PRACTICES, GROUNDING, DISCONNECTS, AND OVERĆCURRENT
PROTECTION ARE OF PARTICULAR IMPORTANCE. FAILURE TO OBSERVE
THIS PRECAUTION COULD RESULT IN SEVERE BODILY INJURY OR LOSS OF
LIFE.
DANGER
DO NOT TOUCH THE CONNECTORS ON THE FACEPLATE IF THERE IS
POWER ON THE WIRES ATTACHED TO THE PLUG CONNECTOR SCREW
TERMINALS. ALWAYS TURN OFF POWER BEFORE HANDLING A
CONNECTOR THAT IS WIRED. FAILURE TO OBSERVE THIS PRECAUTION
COULD RESULT IN SEVERE BODILY INJURY OR LOSS OF LIFE.
CAUTION
THE ANALOG RAIL MODULE IS DESIGNED TO BE POWERED BY EITHER 24
VDC OR 120 VAC. CONNECT THE PROPER POWER SOURCE TO THE
MODULE. FAILURE TO OBSERVE THIS PRECAUTION COULD RESULT IN
DAMAGE TO OR DESTRUCTION OF THE EQUIPMENT.
3.1 Wiring
To reduce the possibility of electrical noise interfering with the proper
operation of the control system, exercise care when installing the
wiring between the module and the external hardware.
Use shielded twisted pair for all wiring between the Analog Rail
module and the external hardware. Beldent 8761 or an equivalent
cable type is recommended. Cable lengths should be limited to 50
feet maximum. For detailed recommendations refer to IEEE 518.
