BEFORE FIRST USE
Upon receipt of the goods, check the packaging for
integrity and open it. If the packaging is damaged, please
contact your transport company and distributor within 3
days, and document the damages as detailed as possible.
Do not turn the package upside down! When transporting
the package, please ensure that it is kept horizontal and
stable. Please keep all packaging materials (cardboard,
plastic tapes and styrofoam), so that in case of a problem,
the device can be sent back to the service centre in
accurate condition.
DISPOSING OF PACKAGING
The various items used for packaging (cardboard, plastic
straps, polyurethane foam) should be conserved, so that
the device can be sent back to the service center in best
conditions in case of problem!
INSTALLING THE APPLIANCE
Appliance location
The work surface where the device will be located must be
suitable for the size of the appliance, please refer to the
measurements.
The work surface must be levelled, dry, heat-resistant and
at a fitting height from the ground to enable a proper use
of the device.
The power cord connected with the appliance must be
properly grounded and correspond to the technical details.
DC POWER SUPPLY OPERATION
1.
Place the device on a stable surface and connect the
power cable to a power source in accordance with
the power supply name plate.
2.
Use on/off switch (11) to turn on the power supply.
3.
Read parameters of the power source connected to
the device.
4.
Using channel III current will be constant, whereas
the voltage can be set using the selector (20). Once
the output voltage parameters have been set,
connect the external load to appropriate poles (+)
and (-).
5.
For the first two channels, select working mode using
the selector (10).
