Initial operation

The laboratory power supply is not a charger. To charge batteries, use suitable
chargers with a charging current cut-off.
During a longer period of operation under nominal load, the surface of the hous-
ing will heat up. Attention! Risk of burns! Therefore, make sure that there is ade-
quate ventilation of the power unit and never operate it partly or fully covered to
avoid any damage.
When connecting a consumer ensure that it is not connected when switched on.
A switched on consumer can result in sparks when connecting to the output ter-
minals of the power supply, which in turn can damage the sockets or the con-
nected cables and/or their clamps.
If your power supply is not required, disconnect it from the mains.
Connecting the power cable
• Connect the supplied earthing mains cable to the low-power device installation socket (25) on the
power supply. Ensure a tight fit.
• Connect the power cable to a shockproof mains socket with protective grounding.
Setting up the device
Place the laboratory power supply on a stable, level and robust surface. Make sure that ventilation slots
in the casing are not covered up.
Switching on
Switch on the power unit on the mains switch (1). The power unit performs a silent system check for
approx. 1 to 2 seconds (no display) and then indicates the result by illuminating all displays (except for
„OUTPUT ON“ and „SLAVE“). If the dual display shows „0000“, the laboratory power unit is ready for
operation.
Presetting the top voltage limit
Your laboratory power unit features various protective measures to protect consumers from damage due
to malfunctioning (e.g. increased current consumption of the consumer) or overvoltage (wrongly set out-
put voltage). You have to adjust these protective parameters according to your requirements and you
can also change them at any time.
