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 Intesis gateway and/or
any other equipment connected to it.
The Intesis gateway 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.
The Intesis gateway cannot be installed outdoors or exposed to direct
solar radiation, water, high relative humidity or dust.
The Intesis gateway must only be installed in a restricted access
location.
In case of wall mount, fix firmly the Intesis device on a not vibrating
surface following the instructions next.
Disconnect always power of any wires before manipulating and
connecting them to the Intesis gateway.
Respect always the expected polarity of power and communication
cables when connecting them to the Intesis device
Supply always a correct voltage to power the Intesis, see details of
voltage range admitted by the device in the technical characteristics
below.
CAUTION: The device is to be connected only to networks without
routing to the outside plant, all communication ports are considered for
indoor only and can be connected SELV circuits only.
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 touching the unit.

INSTALLATION
Follow instructions next to properly install the gateway.
Mount the Intesis device on the wall or inside a close electrical junction
box (respect the safety instructions given in this document).
Disconnect the KNX power supply from the KNX bus.
Connect the communication cables to the Intesis device, see details on
CONNECTIONS below.
Reconnect the KNX power supply to the KNX bus.
Connect EIA485 device(s) to its power supply.
NOTE:
The device cannot be installed in air-handling space.
CONNECTIONS
Owner’s Record
The serial number is located at the rear of the gateway.
Record this information in the space provided below.
Refer to it whenever you contact upon your gateway
dealer or support team regarding this product.
Serial No.
KNX Port
Connect the KNX TP1 bus to conn and - of gateway
’s KNX port.
Respect the polarity and use a KNX standard cable.
Port A / Modbus RTU
Connect the EIA485 bus to connectors A2 (A-), A3 (B+) and A1 (SNGD)
of gateway
’s Port A. Remember the characteristics of the standard
EIA485 bus: maximum distance of 1200 meters, maximum 32 devices
connected to the bus, bus polarization and in each end of the bus it must
be a termination resistor of 120 Ω.
CONFIGURATION
IMPORTANT
:
If the INKNXMBM1000100 gateway is not placed at one end of the Modbus
channel, the terminal
resistor should be deactivated. Remove Jumper 1 to deactivate the 120 Ω
terminal resistor.
The bus should be polarized only in one location on the line. The INKNXMBM1000100 incorporates
2 jumpers to introduce polarization to the line. It is recommended to keep polarization in the master
only. If other device is polarized, remove jumpers 2 and 3 to deactivate polarization in the gateway.
Use the
ETS
to configure the gateway.
Follow the instructions on the user’s manual for configuring and
commissioning the interface. See below how to obtain the user’s manual
and ETS database.
