Notes:
1. Must use NEC Class 2 or Limited Power Source (LPS) and SELV rated power supply.
If using DC power supply:
•Respect polarity applied of terminals (+) and (-). Be sure the voltage applied is within the range admitted (9 to 30 Vdc).
The power supply can be connected to earth but only through the negative terminal, never through the positive terminal.
If using AC power supply:
•Make sure the voltage applied is of the value admitted (24 Vac). Do not connect any of the terminals of the AC power
supply to earth, and make sure the same power supply is not supplying any other device.
2. Modbus connection. Only one type of Modbus connection can be used simultaneously, Modbus RTU EIA485, or Modbus RTU
EIA232, the type to use must be selected within the software LinkBoxEIB.
Modbus RTU EIA485 connection: Connect the EIA485 bus to the connector Modbus RTU EIA485 of IntesisBox. Respect
the polarity. Remember the characteristics of the standard EIA485 bus: maximum bus distance of 1200 meters, maximum
32 devices in the bus, and a termination resistor of 120 ohm in each end of the bus. IntesisBox incorporates and internal
circuit for bus biasing with termination resistor incorporated, so if IntesisBox is installed in one of the ends of the bus it is
not necessary to connect an additional termination resistor in that end.
Modbus RTU EIA232 connection: Connect the EIA232 cable coming from the Modbus RTU slave to the connector
Modbus RTU EIA232 of IntesisBox, this is a DB9 male connector (DTE) in which only the lines TX, RX and GND are
used, see pinout of this connector in the user's manual. Respect the maximum distance of 15 meters for this EIA232 line.
3. Use the software LinkBoxEIB to configure IntesisBox. Consult the user's manual for details.
