To install the PM500 into an instrument panel e Remove the mounting brackets e Slide the PM500 into the panel cutout e Replace the mounting brackets and tighten the bracket screws do not over tighten the bracket screws Allow a minimum of 1 5 inches clearance on all sides of the PM500 2 58 Te Mi IE 5 13 atts t 01943 602001 sales issltd co uk b www issitd co uk Wiring Practices for Industrial Equipment 1 All control signals must be shielded cable The shield must be tied to common or earth ground at the receiving end only In some environments earth ground may contain excessive electrical noise If you have problems using earth ground as a shield tie point switch the shields to signal common All connections to the controller are considered signal unless they carry AC power 2 Never use a shielded cable with unused conductors The unused conductors act as antennas Attempting to tie the unused conductors to ground or other signals just creates different antenna configurations In many cases unshielded wire would have received less electrical noise Always insure that a shielded cable with the correct number of conductors is pulled 3 All control signals must be separated from power wiring Power wiring includes any AC or DC voltages with a current potential of greater than 1 Amp or a voltage greater than 24 V This includes but is not limited to 115 VAC 230 VAC and 460 VAC Do not bundle shielded cable
