SWITCH AND CONNECTOR ETC. LOCATION ON PCB
NOTE:
Ensure proper space for all connectors when mounted.
CAUTION:
Risk of explosion if battery is replaced by an incorrect type. Dispose of used
batteries according to the instructions.
IMPORTANT:
Tight the Power Supply and the LON cables to one of the 4 cable tie holes xed
to the casing with the plastic ties inside the BACnet
®
Gateway for VRF System. Do not use 2
holes to tie one cable.
Power Supply
Connect mains to the power supply connector as:
1.- Brown: Line (L)
2.- Yellow: Earth / Ground (E)
3.- Blue: Neutral (N)
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 or higher cable.
VRF Network
Connect the LON bus to connectors A (-), B (+) and (SGND) of gateways PCB. Respect the
polarity.
Console Port
Connect a mini-type B USB cable from your computer to the gateway to allow communication
between the Conguration Software and the gateway. Ethernet connection is also allowed for
conguration.
