5.10 How to connect monitoring system - RS485 Serial line
The Adr parameter is the number to identify each electronic board. Address duplication is not
permitted, in this case the communication with monitoring system is not guaranteed (the Adr is
also the ModBUS address).
1) Terminals [31] [+] and [32] [-].
2) Use shielded twisted cable. For example Belden® 8762 o
8772 or cat 5 cables.
3) Maximum distance 1Km.
4) Don’t connect the shield to the earth or to GND terminals
of the device, avoid accidental contacts by using insulating
tape.
6. Mounting & installation
The instruments are suitable only for internal use.
Instrument XC660D shall be mounted on an omega DIN rail
The ambient operating temperature range is between -10÷60°C.
Avoid locations subject to heavy vibration, corrosive gases or excessive dirt. The same applies to
the probes. Ensure ventilation around the instrument.
6.1 VC660 – KEYBOARD INSTALLATION
