T u rn off the POWER s w itches on all po w er s u pply u nits to be connected
in parallel.
p. 3-6

Remove the OUTPUT terminal cover.
p. 3-4
3
Connect the load w ires to the o u tp u t terminals of the master and slave
u nits.
4
As sho w n in Fig.6-5, connect the load w ires of the master and slave
u nits to the load or the relay terminal block.
Use load cables with sufficient current capacity. In addition, use the shortest load cables of
the same length and cross-sectional area from each power supply to the load.
Wire the signal cable of the J1 and J2 connectors and load cables as far apart as possible.
5
Connect the o u tp u t terminals (+ or) of the master and slave u nits to the
chassis terminal.
Use the same polarities for the output terminals of the master and slave units.
If you are using the master and slave units under floating conditions, do not connect
the output terminals to the chassis terminal.
6
Attach the OUTPUT terminal cover.
If slave units 3 and 4 are available, connect them in a similar manner.
6.1.3 Master-Slave Parallel Operation Setup
Designating the master and slave units
p. 4-19
Turn the output off and designate the master and slave units of the master-slave
parallel operation. Set CF26 to 0 for the master unit and 1 for the slave units.
The settings take effect when you exit from the CONFIG settings.
Setting the number of units in Master-Slave Parallel Operation
(Including the Master unit)
p. 4-19
Turn the output off and set the number of units (CF24) in Master-Slave Parallel
Operation.
The setting conditions become effective when you exit from CONFIG settings.
• Make sure to match the number of units in Master-Slave Parallel Operation for the
setting number (CF24) and the actual number of connected units. If the setting
number of units are different from the actual number of units, it is unable to set
properly for such a current value setting (including EXT CC CONT), overcurrent
protection (OCP) setting, and also the measured current value will not be appeared
properly on the display.
• When the master unit is connected to the system in Master-Slave Parallel Operation,
the master unit can not be operated properly as stand alone condition even if the
(CF24 “Setting the number of units in Master-Slave Parallel Operation”) is set for
“1” by the CONFIG setting. If you wish to use the master unit as a stand alone
condition, it is necessary to disconnect the parallel operation cable and set the (CF24
“Setting the number of units in Master-Slave Parallel Operation”) for “1”. And if
you wish to change the number of units in the system, set the master unit for the
desired number of units by CONFIG (CF24) setting, and disconnect the parallel
cable for the unit which will not be used.
