4. INSTALLATION AND START UP
This section contains information instructions and warnings that the user must follow by its own security
and to ensure safe operation of the device.
WARNING! PFC max regulators are usually connected to equipment containing
capacitors, which remain charged after removing supply voltage. To avoid risk of electric
shock, you must wait at least 5 minutes between the disconnection of the equipment
and handling of the internal components thereof.
Any handling or use of equipment in different way or conditions to that specified
by the manufacturer, may compromise the user safety.
In case that some damage or deterioration signs are detected in the device or a wrong operation is
observed, disconnect the supply voltage and contact Iskra authorized technical service.
To safely use the PFC max 6 and PFC max 12 it is important that people installing it or handling it follow
the usual safety precautions stated in the LV or MV Electrical Code Rules of each Country as well as the
different warnings stated in this instruction manual.
