Example of connecting two slave units
1
Check that all electronic loads that you will connect in parallel operation
are turned off.
2
Connect the load input terminals of each electronic load to each other.
Refer to the connection diagram shown above to connect the load input terminals of
multiple electronic loads that are the same type to each other in parallel.
3
Use the optional flat cable to connect the master unit's OUT parallel
connector to the first slave unit's IN parallel connector.
Be extremely careful when you connect the units to each other. Connecting them
incorrectly may damage them.
4
Use the optional flat cable to connect the first slave unit's OUT parallel
connector to the second slave unit's IN parallel connector. Continue
connecting all the remaining slave units in the same manner.
This completes the connection procedure for parallel operation using the same type
of electronic loads. Next, configure the settings on the master and slave units.
5
Turn all the electronic loads on.
6
On the master unit, from the menu, select "2.Configuration" > "1.Master/
Slave" > "Operation" > "MASTER."
7
On the master unit, from the menu, select "2.Configuration" > "1.Master/
Slave" > "Parallel,"and then specify the total number of units that are
connected in parallel.
Specify the total number of units, including the master unit. Be sure that you specify
the same number of units that are actually connected.
8
On a slave unit, from the menu, select "2.Configuration" > "1.Master/
Slave" > "Operation" > "SLAVE."
Make this setting on all slave units.
9
Turn all the POWER switches off.
The menu settings are applied. This completes the configuring of the master unit and
slave unit settings.
