WARNING!
Danger because of faulty installation and initial commissioning!
Installation and commissioning require qualified personnel with adequate experi-
ence. A installation fault can cause danger situations or large damage of property.
Therefore:
m
Only personnel from manufacturer or qualified personnel operate while installation
and initial commissioning
DANGER!
Risk of fatal injury from electrical current!
Inevitably, when operating this electrical device, certain parts of it are energized with
hazardous voltage.
Therefore:
m
Pay heed to areas on the device that could be dangerous during the electrical in-
stallation.
m
Pay heed to areas on the device that could still be electrically energized after op-
eration.

DANGER!
Risk of fatal injury from electrical current!
Stored electric charge.
Discharge time of the system = discharge time of the device with the longest DC link
discharge time.
Therefore:
m
Do not touch electrically live parts before taking into account the discharge time of
the capacitors.
m
Pay attention to the corresponding notes on the device.
m
If additional capacitors are connected to the DC link, the DC link discharge can
take a much longer time. In this case, the necessary waiting period must itself be
determined or a measurement made as to whether the equipment is de-energized.
This discharge time must be posted, together with an IEC 60417-5036 (2002-10)
warning symbol, on a clearly visible location of the control cabinet.
