8-4. Connection Methods
Refer to the instruction manual supplied with the interface boards for the
mounting method in the PSF-H Series power supply units.
Be sure to confirm that power is off before mounting the interface board for safe
operation.
The following shows an example of connecting several PSF-H Series power
supply units through the local buses.
Fig. 8-2 Local bus Connection
The input and output of the interface board need not be discriminated for local bus
connection.
Use as short modular cables as possible. Short-circuit the jumper pins (CN2)
of the interface units at both ends with the shorting connectors

See
“Fig. 8-1 Sketch of Interface Boards”
for the CN2.

Keep the disconnected connectors in safe without losing them.
Disconnect the CN2 from the interface board of system addresses 2
and 3 in the example shown in
Fig. 8-2 Local bus Connection.
