Installation
•
The drives must be installed and cooled according to the instructions given in the
corresponding documentation.
•
The ambient air must not exceed degree of pollution 2
according to EN 61800−5−1.
•
Ensure proper handling and avoid excessive mechanical stress. Do not bend any components
and do not change any insulation distances during transport or handling. Do not touch any
electronic components and contacts.
•
Drives contain electrostatic sensitive devices, which can easily be damaged by inappropriate
handling. Do not damage or destroy any electrical components since this might endanger your
health!
Electrical connection
•
When working on live drives, observe the applicable national regulations for the prevention of
accidents.
•
The electrical installation must be carried out according to the appropriate regulations (e.g.
cable cross−sections, circuit breakers, fuses, PE connection). Additional information can be
obtained from the documentation.
•
This product can cause high-frequency interferences in non-industrial environments, which
can require measures for interference suppression.
Operation
•
If necessary, systems including drives must be equipped with additional monitoring and
protection devices according to the valid safety regulations (e.g. law on technical equipment,
regulations for the prevention of accidents). The drives can be adapted to your application.
Please observe the corresponding information given in the documentation.
•
After the drive has been disconnected from the supply voltage, all live components and power
connections must not be touched immediately because capacitors can still be charged. Please
observe the corresponding stickers on the drive. All protection covers and doors must be shut
during operation.
Burn Hazard
The heat sink (housing) of the drive can have an operating temperature of > 80 °C: Contact with the
heat sink results in burns.
Caution - Risk of Electric Shock!
•
Before servicing, disconnect supply, wait 5 minutes and measure between PWR+ and PGND to
be sure that the capacitors have discharged below 42 VDC.
•
The power terminals Ph1+, Ph1-, Ph2+, Ph2- and PWR+ remain live for at least 5 minutes after
disconnecting from the power supplies.
Grounding
All metal parts that are exposed to contact during any user operation or servicing and likely to
become energized shall be reliably connected to the means for grounding.
