Installing And Wiring Your Module
Read this chapter to install and wire your module. This chapter covers:
• avoiding electrostatic damage
• determining power requirements
• setting the DIP switch
• selecting a rack slot
• inserting your module into the rack
• wiring your module
Note that although your module has a jumper on its printed circuit board,
this jumper is for the manufacturer’s use only. Also, your module was
calibrated by the manufacturer, so you don’t need to perform this task.
Important - For UL and CUL compliance, power and input/output (I/O)
wiring must be in accordance with Class I, Division 2, wiring methods
[Article 501-4 (b) of the National Electrical Code , NFPA 70] and in
accordance with the authority having jurisdiction. Also, you must observe
the warnings shown below. Failure to observe these warnings can cause
personal injury.
