8-4. Connection Methods
Refer to the instruction manual supplied with the interface boards for
the mounting method in the PSF 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 Series
power supply units through the local buses.
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

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.
