The LTX is installed as follows
1) Mount the LTX on a standard symmetric DIN
rail. A clearance of 85mm above and 105mm
below the DIN rail centreline should be allowed
and 155mm horizontal clearance. See the
figure to the right.
2) Connect the LTX Power connector (black) to a
1.5VA 24Vdc supply. The connection is
polarity independent. Do not power the device
up.
3) Connect the LonWorks network to the LTX
connector labelled ‘Network’ (orange) using unshielded twisted pair; the connection is
polarity independent. Multiple devices can be daisy-chained.
4) Daisy-chain the LonWorks connection from the LTX to a pair of screw-terminals
mounted on the DIN rail adjacent to the LTX. This is for engineering purposes and
allows easy access to the network.
5) Add a network terminator to the LonWorks network if specified.
