Misuse; Explosion Protection; Residual Risks; Safety And Warning Signs On Frequency Inverter - BONFIGLIOLI ACTIVE CUBE 201 Operating Instructions Manual

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.
2.3

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.
The manufacturer shall not be held liable for any damage resulting from such misuse. The sole risk
shall be borne by the operator.
2.3.1

Explosion protection

The frequency inverter is an IP 20 ingress protection rating device. For this reason, use of the device
in explosive atmospheres is not permitted.
2.4

Residual risks

Residual risks are special hazards involved in handling of the frequency inverter which cannot be
eliminated 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 disconnection
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, check 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.
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 is not the middle of the electrical cabinet modules.
