•

IntesisBox must be installed by accredited electrician or similar technical personnel, following all the safety instructions

given here, and in accordance always with the country legislation for installation of electric equipment.

• IntesisBox can not be installed outdoors or exposed to direct solar radiation, water, high relative humidity or dust.

• IntesisBox must only be installed in a restricted access location

• In case of wall mount, fix firmly IntesisBox on a not vibrating surface following the instructions below.

• In case of DIN rail mount fix IntesisBox properly to the DIN rail following the instructions below.

• Mounting on DIN rail inside a metallic cabinet properly connected to earth is recommended.

• Disconnect always power of any wires before manipulating and connecting them to IntesisBox.

• A power supply with an NEC Class 2 or Limited Power Source (LPS) and SELV rated is to be used.

• Respect always the expected polarity of power and communication cables when connecting them to IntesisBox.

• Supply always a correct voltage to power IntesisBox, see details of voltage range admitted by the device in the technical

characteristics below.

• This device was designed for installation in an enclosure. To avoid electrostatic discharge to the unit in environments with
static levels above 4 kV precautions should be taken when the device is mounted outside an enclosure. When working in
an enclosure (ex. making adjustments, setting switches etc.) typical anti-static precautions should be observed before

to

uching the unit

Safety Instructions

WARNING

Follow carefully this safety and installation instructions. Improper work may lead to serious harmful for your
health and also may damage seriously the IntesisBox and/or any other equipment connected to it.

Use the software LinkBoxEIB to configure IntesisBox, follow the instructions of the user's manual for more
details.

See instructions to download and install the latest version of LinkBoxEIB and
the user's manual at

http://www.intesis.com/down/eib/linkboxeib.html

Configuration and setup

• Disconnect from mains the power supply before connecting it to IntesisBox.

• Disconnect power of any bus or communication cable before connecting it to IntesisBox.

• Mount IntesisBox on the wall or DIN rail following the instruction given below, respecting the safety

instructions given above.

• Connect a NEC Class 2 or Limited Power Source (LPS) and SELV rated power supply to IntesisBox,
respect the polarity if DC power or Line and Neutral if AC power. Apply always a voltage within the range
admitted by IntesisBox and of enough power (see technical characteristics).

• Circuit-breaker must be used before the power supply. Rating 250V-6A

• Connect the communication cables to IntesisBox, see details on the user's manual.

• Power IntesisBox and the rest of devices connected to it.

1. Separate the fixing clips in the bottom of the box, pushing them to the outside until hear the "click" which
indicates that now the clips are in position for wall mount, see in the figure below.

2. Use the holes of the clips to fix the box in the wall using screws. Use the template below for the wall holes.

With the clips of the box in their original position, insert first the box in the upper edge of the DIN rail and later insert
the box in the down part of the rail using a small screwdriver and following the steps n the figure below.

Connections

________________________________________________________________________________________

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.
