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, 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.
Protection of persons
The power terminals Ph1+, Ph1-, Ph2+, Ph2- and PWR+ remain live for at least 5 minutes after
disconnecting from the power supplies.
Before servicing, disconnect supply, wait 5 minutes and measure between PWR+ and PGND to be
sure that the capacitors have discharged below 42VDC.
The metal case of the drive can have an operating temperature of > 80 °C: Contact with the metal
case can results in burns.
