presence of the RJ45 connector in CON C (if this cable is
connected to another unit).
If the RJ45 connector is removed from CON C when the unit
is turned on, the output will shutdown to avoid accidental
damage.
If the cable is inserted when the unit is turned on, the output
shuts down, the unit changes to Remote CV / CC, the
Keylock will be activated and the output will turn back on
.
If DIP switch 4 of SW1 is operated when the unit is turned on,
the output will shutdown to avoid accidental damage.
Stack the units to create a minimum distance between the
units. Keep the load close to the master.
Use copper strips (preferred) or short thick cables to connect
the units. Make sure the strips are mounted with a minimum
length to keep the voltage drop between a unit and the bus
bar below 10 mV. Also keep the strips close to each other to
have a low inductance.
Not following these instructions can cause instability.
The S- and S+ could be connected to the load if desired, but
this is not recommended because of the complexity and
possible instability.

PARALLEL OPERATION OF FAST
PROGRAMMING VERSIONS:
Master / Slave operation is not recommended.
Normal parallel operation can give problems, each
combination has to be tested first in combination with the
load.

MASTER / SLAVE MIXED SERIES / PARALLEL
OPERATION
For complex combinations as mixed series - parallel, always
use a MASTER / SLAVE SERIES ADAPTER.
See fig. 4 - 12 for an example of how to connect 2 units in
series in parallel with 2 units in series, controlled by 1 master.
Set the programming mode with the knob Remote / Local on
the front panel. The serial slaves must be in Remote CV- and
CC-mode. The parallel slave must be in Remote CC-mode
and the CV-potmeter must be fully opened.
Note: A Master / Slave combination can always be
programmed, also with the IEEE488/RS232 controller (PSC-
488 / PSC-232).
