Example of electrical connection of an EPJ LCD user interface
The following diagram gives an example of the electrical connection of an EPJ LCD user interface for wall installation.
In this example, EPJ LCD is powered by a safety transformer.
CAUTION:
-
do not power another device with the same transformer
-
the maximum connection cable length allowed for the CAN port depends on the baud rate:
-
1,000 m (3,280 ft), with baud rate of 20,000
-
500 m (1,640 ft), with baud rate of 50,000
-
250 m (820 ft), with baud rate of 125,000
-
50 m (164 ft) with baud rate of 500,000.
over 10 m (32.8 ft), use a shielded cable.
In this example, EPJ LCD is powered by a device.
CAUTION:
-
make sure that the current supplied by the controller falls within the limits outlined in the TECHNICAL SPECIFICATIONS section
-
the maximum connection cable length allowed for the CAN port is 10 m (32.8 ft).
