Ɣ
The large central controller may break down by an incorrect wiring.
Ɣ
Communication cabling shall be a minimum of 18-Gauge, two-Conductor, Stranded Copper.
Shielded cable must be considered for applications and routing in areas of high EMI and other
sources of potentially excessive electrical noise to reduce the potential for communication errors.
When shielded cabling is applied, proper bonding and termination of the cable shield is required
as per Johnson Controls guidelines. Plenum and riser ratings for communication cables must be
considered per application and local code requirements.
Ɣ
It is a requirement that communication cables be separated from the power supply wiring and other
electrical device wiring. Maintain at least 12 inches (30cm) separation between communication
cables and wiring from the power supply. If wiring and cables are not secured separately, they
should be run through separate metal conduit tubing. One side of the metal conduit tubing should be
grounded for noise reduction.
Ɣ
Do not connect the power supply wiring to the large terminals for communication at of large central
controller. If the power supply wires are connected incorrectly, the fuse of the printed circuit board will
blow out for protection. If this happens, turn ON DIP switch (DSW2-pin) on the printed circuit board
(PCB), to proceed with unprotected (no fuse) emergency operation.
