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 section 5). Once connected the ON led will turn on.
WARNING!
In order 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.
Connect to Hitachi installation
Use the Port B connector of the Intesis device to connect Hitachi H-Link bus to the Intesis. Remember to follow all safety
precautions indicated by Hitachi.
Connect the Hitachi H-
Link bus to connectors B1 and B2 of gateway’s PortB. Bus is not sensitive to polarity.
Connection to KNX
Connect the KNX TP1 bus to connectors A3 (+) and A4 (-
) of gateway’s PortA. Respect the polarity.
