3.3. Power device

The first step to perform is to power up the device. To do so, a power supply working with any of the voltage range
allowed is needed (check
WARNING! To avoid earth loops that can damage the gateway, and/or any other equipment connected to it, we
strongly recommend:
•
The use of DC power supplies, floating or with the negative terminal connected to earth. Never use a
DC power supply with the positive terminal connected to earth.
•
The use of AC power supplies only if they are floating and not powering any other device.

3.4. Connect to Panasonic VRF installation

Use the PortA connector in the top corner of the Intesis device to connect P-Link bus to the Intesis. Remember to
follow all safety precautions indicated by Panasonic.
Connect the Panasonic P-Link bus to connectors A3 and A4 of gateway's PortA. Bus is not sensitive to polarity.
For the product version supporting 128 units (INMBSPAN128O000), connect the Panasonic P-Link 2 bus to
connectors B1 and B2 of gateway PortB. Bus is not sensitive to polarity.

3.5. Connection to Modbus

3.5.1. Modbus TCP

The gateways Ethernet port connection is used for Modbus TCP communication. Connect the communication cable
coming from the network hub or switch to the Ethernet port of Intesis. The cable to be used shall be a straight
Ethernet UTP/FTP CAT5 cable.
TCP port to use (default 502) and keep alive period must be configured.
IP settings of the gateway (DHCP status, own IP, netmask and default gateway) must be configured as well.

3.5.2. Modbus RTU (only for INMBSPAN016O000 and INMBSPAN064O000)

Connect the communication cable coming from the motbus network to the port marked as Port B of the Intesis.
Connect the EIA485 bus to connectors B1 (-), B2 (+) and B3 (SNGD) of gateway's PortB. Respect the polarity.
Remember the characteristics of the standard EIA485 bus: maximum distance of 1200 meters, maximum 32 devices
(without repeaters) connected to the bus, and in each end of the bus it must be a termination resistor of 120 Ω. The
gateway has an internal bus biasing circuit that incorporates the termination resistor. Bus biasing and termination
resistor for EIA485 can be enabled for PortB by means of a dedicated DIP switch.

3.6. Connection to Modbus TCP/IP (Energy meters)

Use the Ethernet connector to communicate with the Modbus Energy meters.
Once the Energy meters are connected, running and tested, make sure they are available from the Intesis device
LAN network/IP before going to the next step.

3.7. Connection to PC (Configuration tool)

This action allows the user to have access to configuration and monitoring of the device (more information can be
found in the configuration tool User Manual). Two methods to connect to the PC can be used:
•
Ethernet: Using the Ethernet port of Intesis.
•
USB: Using the console port of Intesis, connect a USB cable from the console port to the PC.
