8. START-UP
The laboratory power unit 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 housing will heat up.
Attention! Risk of burns! Therefore, make sure that there is adequate 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 terminals of the power unit, which
in turn can damage the sockets or the connected cables and/or their clamps.
If your power unit is not required, switch it off and disconnect it from the mains. The displays
remain on for a few seconds after it is switched off to unload the internal capacitators and to store
the last parameters that were set.
