Independent mode: each output channel is connected to an independent load. In this
way, the power supply could, for instance, feed three independent loads at the same
time and with different capacities, voltages, currents, etc.
Please be sure that no electrical connection between the channels exists, i.e.
that the loads are completely independent. Keep in mind that, if two channels
are interconnected, a shortcircuit may appear in voltage based modes.
Parallel mode: all three channels are connected in parallel to increase the maximum
power supply output current. It is mandatory to shortcircuit by hardware the three
output channels. All operation modes are available in this connection mode.
Four quadrant mode: the four quadrant mode is a particular case of the independent
mode in which the power supply may only be operated as a voltage source. In this case
the load is connected only between phases without any reference to the N phase. As
far as the load has no reference to the negative phase, the connected phases may be
charged at any potential (keep it in mind).
In order to operate the output phases, Cinergia recommends a start-up voltage of
200V for each connected phase. From this initial voltage, sum the desired setpoint
divided by 2 to one phase and subtract the same value to the other phase.
Changing the polarity of the load implies switching the setpoint values in the phases.
Due to the blanking time of the IGBTs, it is not possible to operate in this mode with
voltages near 0V.
Please remember to disconnect the equipment before modifying the connection
mode.

Working with the equipment
Before powering the cabinet check step by step the following items (if the
cabinet is powered for the first time, place the fuses in the fuseholder
before proceeding):
The power supply output must be disconnected:
