4. 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 on the side and the air outlet at 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 gua-
ranteeunimpededairow.
4.3 Opening the device
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 person-
nel, which is instructed about the hazards of electrical current.
5. 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 tech-
nical specs table), which is accessible inside the mains socket
(models up to 640W) or in the fuseholder at the rear.
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 ap-
plication, always take care for the nominal values of the load.
The cross section of the leads depends on several conditions,
like the output current, the lead length and the ambient tempe-
rature.
Up to 1.5m lead length we recommend to use:
up to 5A: 0.5mm², up to 10A: 0.75mm²
up to 15A: 1.5mm² up to 20A: 2.5mm²
up to 40A: 6mm², up to 60A: 16mm²
per cable(exiblewire).
The outputs “+” and “-“ are not grounded, so that one of them
may be grounded if necessary.
