General
4.1
Prologue / Warning
This user instruction manual and the device are intended to be
used by users who know about the principle of a power supply.
The handling of the device should not be left to persons who
are unaware of the basic terms of electrotechnology, because
these are not described in this manual. Inappropriate handling
and non-observance to the safety instructions may lead to a
damage of the device or loss of warranty!
4.2
Cooling
The air inlets in the bottom side and the air outlets on the rear
have to be kept clean to ensure proper cooling. Take care of at
least 10cm distance at the rear to any surrounding objects in
order to guarantee unimpeded air flow.
4.3
Maintenance / repair
When opening the unit or removing parts from the inside with
tools there is risk of electric shock by dangerous voltages.
Open the unit only at your own risk and disconnect it from the
mains before.
Any servicing or repair may only be carried out by trained
personnel, which is instructed about the hazards of electrical
current.

Installation
5.1
Visual check
After receipt, the unit has to be checked for signs of physical
damage. If any damage is found, the unit may not be operated.
Also contact your dealer immediately.
5.2
Mains connection
The unit is grounded via the mains cord. Thus the unit may
only be operated at a mains socket with grounding contact.
This must not be interrupted by an extension cable without
ground conductor!
The unit is fused with a 5 x 20mm safety fuse (for value see
technical specs table), which is accessible on the rear.

PS 8000 DT Series
5.3
DC output terminal
The power output is located on the front of the device.
The output is not fused! In order to avoid damage to the load
application, always take care for the nominal values of the load.
The cross section of the load leads depends on several condi-
tions, like the output current, the lead length and the ambient
temperature.
Up to 1.5m lead length we recommend to use:
up to 10A:
0,75mm²
up to 30A:
4mm²
up to 60A:
16mm²
per cable (flexible wire).
The outputs "+" and "-" are not grounded, so that one of them
may be grounded if necessary.
Attention!
The 4mm socket on the DC output terminals of the 1000W
and 1500W models is only specified up to 32A!
Attention!
When grounding one of the output poles always check if
one of the poles of the load (eg. electronic load) is also
grounded. This could result in a short-circuit!
Attention!
Watch the potential shift of the output poles when using
series connection! Grounding is hereby only recommen-
ded at the pole with the lowest potential against ground.
5.4
Terminal „Sense" (Remote sense)
In order to compensate the voltage drop along the load leads
(max. 1V per lead), the power supply can „sense" the voltage at
the load instead at the output. It will regulate the output voltage
so that the desired voltage is provided to the load.
The connection for remote sense is done at the terminal „Sy-
stem Bus" on the rear side, pins 1 and 2. See section 3.1.
Attention!
(+) Sense must only be connected to (+) at the load appli-
cation and (–) Sense must only be connected to (–)! Else
both systems can take damage.
For additional information also see section 7.7.
5.5
Interface card slot
The unit can be equipped with an optional interface card. The
slot to insert the card is located at the rear side. Further infor-
mation about the interface cards can be found in section „9.
Digital interface cards".
