Wiring
WARNING:
A VFD can be switched on unintentionally if
the serial bus installation is not operated
correctly. Only personnel who are qualified
and trained in installing systems of this type
should start the bus.
DIP Switch
Leave DIP switches OFF for proper operation of the
LON Interface.
WIRING
Wiring must conform to local codes and ordinances.
WIRE ROUTING
Maintain a minimum of 5 ft (1.5 m) between VFDs and
network or sensor wiring.
If it is necessary for network and sensor wring to cross
VFD wiring, it should cross at 90-degree angles.
POWER
The LON Interface receives power through its SED2
VFD connection. If VFD power is switched off, the
LON Interface will not communicate on the network.
LONTalk® NETWORK
The LONTalk network connection is on the bottom
edge of the LON Interface (Figure 2). Figure 5 shows
the wiring schematic for this connection. See
www.echelon.com for more details on the network
cable and the FTT-10A connector.
The installation is now complete.
NOTE: This connection supports twisted pair,
unshielded, polarity-insensitive, peer-to-peer
communications at 78 Kbps.
