It is recommended that shielded cable be used for the remote unit wiring and that the
conduit be run six (6) inches from all other parallel conduit runs. The remote unit wiring
must include a ground wire that is connected to the chassis of the remote control and to
the chassis of the main enclosure. The length of cable that is used should not exceed
fifty (50) feet. It is recommended to use 14 conductor #22 AWG shielded cable for
connecting the remote unit.
