WIRING GUIDELINES AND BEST PRACTICE INFORMATION
(continued)
*NOTE:
Limitation on distance is limited by the data communications limit being reliable, not by the power dropout.
The table of cable runs apply only to a single PCP device connected to an IC-XX-II RS485 port. If more PCPs are connected through
the “third party integration” ports, then the table described does not apply. In this case the total 1000 ft of cable runs must be the
total cable run shared between all 16 ports (in case there are 2 PCP daisy chained). Same reasoning applies for three or more PCPs
connected.
