C. Wiring connection of gateway:
Remarks:
1)Power The power of gateway is AC12V and could be getted from port A and B on the
communication terminal block of outdoor master unit and slave unit. There cann
t
be
any error when connecting, or the gateway will be burnt off.
2)LON/LON(LONWORKS communication)connector: connect with the gateway of other
master unit and LONWORKS communication connector of internet server, no polarity
requirement.
3)HBS/earth wire(serial signal of master unit)wiring: connect with the output port of
serial signal CN35 of the master uint PCB, get the parameter of slave unit from serial
signal, could not detect slave unit data when in reverse connection. Polarity is
required. When using communication wire 0010450044, black wire is connected to the
HBS terminal of gateway, and white wire is connected to the earth wire on the right of HBS.
4)Count/ earth wire(pulse signal)wiring: connect pulse ammeter to get the power
consumption recorded in the ammeter. Polarity is required.
HBM/HBM (HOMEBUS communication)port: connect ports P&Q of the communication
terminal block of outdoor master unit and indoor unit, no polarity requirement..
Connect the earth wire terminal of pulse output of ammeter to the earth wire terminal on
the right of count terminal of gateway, and the other terminal of pulse output of ammeter
connects to the count terminal of gateway.
