Power Output
Terminals for connecting the power consumer.
This is a floating output and can be grounded
with the positive or the negative pole.
Output connections may only be connected
and disconnected when the output is
inactive (OUTPUT OFF)! Danger of arcing!
Connecting the Power Consumer
The output leads are connected to the terminal
blocks by means of ring-type cable lugs with the
included M6 x 10 screws. Measurement cables
can be additionally connected to the 4 mm holes.

Remove the safety cap.

Connect the output leads to the terminal
blocks with the provided screws and washers.

An adequate wire cross-section and correct
polarity must be assured. It is advisable to
twist the output leads and to identify polarity at
both ends.

Avoid exerting excessive force at the terminals.

Align the leads to the openings in the safety
cap.

Snap the safety cap back into place.
In order to prevent danger during use,
shock-proof connector cables must be used
when connecting power consumers.

Analog Interface (X13)
• Remote control for output voltage and current
• External measurement of output voltage and current
• Connection of sensing leads in order to compensate for
voltage drops in the output leads
• Linking of several devices for master-slave operation
• Vary internal output resistance
• Control of a selected device function via the floating
trigger input
Air Vents
In order to assure adequate cooling of the
device, the outlet vents for the integrated
fans may not be covered.
Ground Terminal (earth terminal)
The output or cable shields can
be grounded here if shielded
cables or control cables are used
for the analog interface.
