1) Recommended terminations are pre-insulated & must be crimped using approved tooling.
2) RS485 (block "B" terms 14, 16, 18, 20) connections to this communication facility is by screened, twisted pair
cable. On site when wiring other facilities ensure that these terminals are not obscured by other wiring runs. Cable
should be RS485 compliant.
