Gateway for VRF System
NOTE: Mount the device in a vertical position and ensure proper space for all connectors when mounted. Product is
to be connected only to Ethernet and LON networks without routing to the outside plant and connect to outdoor
devices through SELV ports.
Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the instructions.
IMPORTANT: Tie the power supply and the LON cable to the corresponding tie fixture as shown in Figure 6.1.
When doing so, cable must be tied thru only one of the 2 holes of the tie fixture. If cable is tied thru both of the 2
holes of the tie fixture, the cable may become loose and can be dangerous.
Power Supply
Connect mains to the power supply connector as:
1.- Brown: Line (L)
2.- Yellow: Earth / Ground (E)
3.- Blue: Neutral (N)
A readily accessible disconnect device shall be incorporated in the building installation wiring.
Ethernet / BACnet IP (UDP) / Console (UDP & TCP)
Connect the cable coming from the IP network to the connector ETH of the gateway. Use an Ethernet CAT5 cable.
VRF Network
Connect the LON bus to connectors A3 (+), A4 (-) and A1/A2 (SNGD) of gateway's PCB. There are no polarities for
the A3 (+), A4 (-) signals.
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 for configuration.
