(2)WIRING

(A)BACNET/MSTP, JOHNSON N2, AND LONWORKS

(1)The necessary internal wiring for the Gateway is already present except for the BMS network connection that can be made via twisted-pair at terminals A and B. To network multiple units to a single Gateway, the units may be daisy-chained to each other using the network link terminals at the TB3 connection jack on the humidifier logic board. Refer to wiring diagram in section 10-50.

(1)Table #1 refers to the recommended wire types and maximum recommended lengths from the Nortec LINK 2 module to the front-end of the Building Management system. Since communication between the humidifiers and Nortec Links will always occur via a EIA-485 signal type, Nortec recommends using a 18-24 AWG shielded, twisted pair wire between the lead humidifier and each of the slave humidifiers. Cable runs between the Nortec LINKS 2 module and the furthest slave humidifier should not exceed 2,000 feet. Signal boosters or repeaters may be necessary for longer wire runs or where electrical noise interference is prevalent.
