SAFETY INSTRUCTIONS
! WARNING
Follow carefully this safety and installation instructions. Improper work
may lead to serious harm to your health and also may damage seriously the
Intesis device and/or any other equipment connected to it.
The Intesis gateway must be installed by an 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.
In case of DIN rail mount fix the Intesis device 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 the Intesis device.
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 the Intesis device.
Supply always a correct voltage to power the Intesis gateway, see details of
voltage range admitted by the device in the technical characteristics below.
CAUTION: Risk of Explosion if Battery is replaced by an Incorrect Type.
Dispose of Used Batteries according to the instructions. Battery replacement
shall be done by an authorized installer.
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.

CONFIGURATION
Use the Configuration Tool to configure the gateway.
See instructions to download and install the latest version at:
https://intesis.com/docs/software/intesis-maps-installer
Use the Ethernet connection or the Console Port (mini USB type B connector
included) to get communication between the gateway and the configuration tool.
Follow instructions in the user’s manual for more details.
INSTALLATION
Follow instructions next to properly install the gateway.
Disconnect from mains the power supply before connecting it to the Intesis
gateway.
Disconnect the power of any bus or communication cable before connecting it to
the Intesis gateway.
Mount the Intesis gateway 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 the Intesis device, respect the polarity if DC power or Line and
Neutral if AC power. Apply always a voltage within the range admitted by the
Intesis device and of enough power (see technical characteristics).
Circuit-breakers must be used before the power supply. Rating 250V6A.
Connect the communication cables to the Intesis gateway, see details on the
user’s manual.
Power the Intesis gateway and the rest of devices connected to it.
NOTE: The device cannot be installed in air-handling space.
Wall Mount
- Separate the fixing clips in the bottom of the box, pushing them to the outside until hearing the “click” which indicates that now the clips are in position for wall mount, see in the figure below.
- Use the holes of the to fix the box in the wall using screws. Use the template below for the wall wholes.

wall mount
---|---
DIN Rail Mount
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 in the figure
below. 
CONNECTIONS
Power Supply
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 (check table below). 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 the earth, and make
sure the same power supply is not supplying any other device.
Ethernet / Modbus TCP (TCP) / Home Automation / Console (UDP & TCP)
Connect the cable coming from the IP network to the connector ETH of the
gateway. Use an Ethernet CAT5
cable. If communicating through the LAN of the building, contact the network
administrator and make sure traffic on the port used is allowed through all
the LAN path (check the gateway user manual for more information). Default IP
is 192.168.100.246.
PortA / R1/R2 Samsung NASA
Connect the R1 (+) R2 (-) bus of Samsung NASA Outdoor Units to the connectors
A3 (+) A4 (-) of gateway’s
PortA. Respect the polarity.
PortB / Modbus RTU
Connect the EIA485 bus to connectors B1 (B+), B2 (A-), and B3 (SNGD) of the
gateway’s PortB. Respect the polarity. Remember the characteristics of the
standard EIA485 bus: maximum distance of 1200 meters, maximum 32 devices
connected to the bus, and in each end of the bus it must be a termination
resistor of 120 Ω. Bus biasing and termination resistor for EIA485 can be
enabled for PortB by means of a dedicated DIP switch – see table below.
Connect the serial cable EIA232 coming from the external serial device to the
EIA232 connector of
the gateway’s PortB. This is a DB9 male (DTE) connector in which only the
lines TX, RX, and GND are used.
Details of the pinout can be seen in the user’s manual. Respect the maximum
distance of 15 meters.
Console Port
Connect a mini-type B USB cable from your computer to the gateway to allow
communication between the
Configuration Software and the gateway. Remember that Ethernet connection is
also allowed. Check the user
manual for more information.
USB
Connect a USB storage device (not an HDD) if required. Check the user manual
for more information.
