Misuse; Residual Risks - BONFIGLIOLI Active Cube Series Complement To Operating Instructions

The frequency inverters meet the requirements of the low voltage directive 2006/95/EEC and DIN
EN 61800-5-1. CE-labeling is based on these standards. Responsibility for compliance with the EMC
Directive 2004/108/EC lies with the operator. Frequency inverters are only available at specialized deal-
ers and are exclusively intended for commercial use as per EN 61000-3-2.
No capacitive loads may be connected to the frequency inverter.
The technical data, connection specifications and information on ambient conditions are indicated on
the rating plate and in the documentation and must be complied with in any case.
2.2

Misuse

Any use other than that described in "Designated use" shall not be permissible and shall be considered
as misuse.
For, example, the machine/plant must not be operated
 by uninstructed staff,
 while it is not in perfect condition,

without protection enclosure (e.g. covers),

without safety equipment or with safety equipment deactivated,
 when general requirements, such as operating conditions and technical data, are not met.
The manufacturer shall not be held liable for any damage resulting from such misuse. The sole risk shall
be borne by the operator.
2.3

Residual risks

Residual risks are special hazards involved in handling of the frequency inverter which cannot be elimi-
nated despite the safety-compliant design of the device. Residual risks are not obviously identifiable and
can be a potential source of injury or a health hazard.
Typical residual hazards include:
 Electrical hazard
 Danger of contact with energized components due to a defect, opened covers or enclosures or
improper working on electrical equipment.
 Danger of contact with energized components in frequency inverter if no external disconnec-
tion device was installed by the operator.
During operation, all covers must be installed correctly, and all electrical cabinet doors must be closed
to minimize electrical hazards.
When LEDs and other indicating elements on the frequency inverter go out, this does not necessarily
mean that the device is deenergized. Before carrying out any work on the device where contact with
energized parts might be possible, it must be checked in any case, i.e. irrespective of the status of any
indicating elements that may be installed, if the device is deenergized.
Charged capacitors in DC link
Sizes 1 through 7 (up to 132 kW): The DC-link may have dangerous voltage levels even up to 3 minutes
after shutdown.
Size 8 (as from 160 kW): The DC-link may have dangerous voltage levels even up to 8 minutes after
shutdown.
Electrostatic charging
Touching electronic components entails the risk of electrostatic discharges.
Thermal hazards
Risk of accidents by hot machine/plant surfaces, e.g. heat sink, transformer, fuse or sine filter.
Danger of equipment falling down/over, e.g. during transport
Center of gravity may not lie in the middle of the electrical cabinet modules.
