Typical Connections
The following two diagrams illustrate the method of connection.
The first shows the use of the internal connections to wire the external loads
directly to the output connector. Note that pin 50 is a single common supply
pin internally linked to pins 20, 22, 24 and 26. Pin 49 is a single common
supply return pin.
Note the use of a fuse to protect the circuitry.
The second diagram shows an individual load connected directly to the power
supply. Again the use of a fuse is recommended.
