3.3 Power ON
Set the „ON / OFF“ switch to the ON position to turn on the device. The device is equipped with a soft-start delay which
slowly charges the capacities in the power supply to limit the high inrush currents. After about 10 seconds, the power
supply will switch into stand-by mode.
3.3.1 Stand-By Mode
The output is switched off in stand-by mode and the device is ready to set the desired output values. The displays
show a voltage of 0V and a current of 0A, which corresponds to the actual values at the output.
Press the SET button once to enter the setup menu.
Press the SET button once
- FREQUENCY display flashes -> Frequency setting
Press the SET button 2x
- VOLTAGE display flashes -> Voltage setting
Press the SET button 3x
- VOLTAGE display flashes -> FLOAT + percentage setting (default 10%)
Press the SET button 4x
- VOLTAGE display flashes -> FLOAT- percentage setting (default -10%)
Press the SET button 5x
- CURRENT display flashes -> Setting of Over Current Protection value
(In the range 0 - max. output current of the power supply / max. 0 - 50A)
Press the SET button 6x
- Save settings, back to stand-by mode
3.3.3 Setup Menu (CV Version) DF-C61XXX
Press the SET button once to enter the setup menu.
Press the SET button once
- FREQUENCY display flashes -> Frequency setting
Press the SET button 2x
- VOLTAGE display flashes -> Voltage setting
Press the SET button 3 x
- CURRENT display flashes -> setting of the Over Current Protection value
(In the range 0 - max. output current d of the power supply / max. 0 - 50A)
Press the SET button 4x
- Save settings, back to stand-by mode
3.3.4 Setting the output values for constant current sources of the DF-C series (CC version)
Constant current sources of the DF-C series which work in CC mode have no setup menu and a simplified Control
panel. If you are in stand-by mode (output OFF), values can be entered directly using the arrow keys, saving is not
necessary.
3.3.5 Voltage Range Setting (LV / FS)
Press the LV / FS key to switch between the voltage ranges, the currently set voltage range is displayed on the
frequency display for 3 seconds with L for LV and F for FS. Normally the range is LV for 0 - 150V and FS for 0 - 300V,
this may differ for custom-made devices.

4. Optional: Analogue In- / Outputs
Devices of the DF-C series can optionally be equipped with analogue inputs / outputs for setting and reading the
output parameters. The analogue outputs / inputs are accessible via a labeled terminal block which is located either
on the back, the front or behind the service door (depending on device model). The pin assignment is explained on the
terminal block for a simple and straight forward connection.
4.1 Optional: Ext. Output On/Off Ctrl. & Interlock
Input for controlling the status of the output of the laboratory power supply (on / off), switchable as “Interlock” or
external control. This input is configured as a two pin connection, a „true“ state is triggered by shorting the two pins
and a „false“ state is triggered by removing any connection between the two pins of the input.
This option can be configured as either an interlock input, which disables the output of the power supply if the state is
false, or as an external output status control which enables or disables the output of the power supply depending on
the control signal state (true = on/false = off) if the „Output On/Off“ switch of the power supply is always in the ON
position.
4.2 Optional: Potential-free output / configurable output
The output of DF-C series devices in the basic version has a potential to PE, which follows the usual protection
regulations. All models can also be ordered in the following modifications (please see the „DF-C Series Function and
Wiring Diagram“ PDF for details):
1). Configurable output without ELCB
The output of the power supply has no potential to the input (PE), so the output of the device has no protective earth
for loads that may require a PE connection and the load is not protected by a ELCB ! By bridging output N to input N,
the output can be pulled to the input potential, in this case input PE = output PE and the load is protected by the ELCB
installed in the operation environment (Laboratory).
2). Configurable output with built-in ELCB
The model with integrated ELCB offers the following switchable configurations:
A). Potential-free output with its own ELCB
Connections output
L (1, 2, 3): Phase (potential-free)
N: Neutral conductor (potential-free)
GND: In this configuration to use as PE connection for the load
Remark: ELCB triggers as soon as a residual current flows through the GND conductor.
Connections input
L1: Input phase 1
L2: Input phase 2
L3: Input phase 3
N: Neutral conductor
PE: Earth conductor

B). Output with potential to input (potential to input PE)
Connections output
L (1, 2, 3): Phase
N: Neutral →Bridge to input N
GND: Do not connect
Connections input
L1: Input phase 1
L2: Input phase 2
L3: Input phase 3
N: Neutral conductor
PE: Earth conductor
5. Connection of the load
Depending on the model the output / input connections are located on the back, on the front or behind the service
door of the device. We recommend protecting the connectors from wear if the load will be frequently connected and
disconnected by connecting it not directly to the device, but to use an intermediate bridge. In this case, the
intermediate bridge can remain connected to the power supply - so the connection terminal of the power supply is
used less often.
