1.4.3 Safety instructions for transportation and storage

• The ambient conditions given in the product documentation must be observed for
transportation and storage (temperature, humidity, mechanical stress and aggressive
atmosphere).
• Drives contain components sensitive to electrostatic charges which can be damaged by
inappropriate handling. Therefore during installation / removal of drives, provide the
necessary safety precautions against electrostatic discharges (discharge electrostatic charges
of the human body before touching the drive, always place the drive above conductive plates
and avoid touching it with insulating material like synthetic fibres, polymeric materials etc...)
Risk of injury by incorrect handling !
• Incorrect handing of the equipment may cause severe personal injury. Use appropriate tools
for transportation, lifting, handling and mounting. Wear appropriate clothing for accident-
prevention (safety shoes, safety glasses, safety gloves, etc...).

1.4.4 Safety instructions for commissioning

• The high voltages inside the drive imply risk of electric shock. Make sure that drive and
motor are properly grounded accordingly to national regulations. Furthermore the drive,
before switching it on, must be closed in a protective cabinet in order to avoid direct contact
with accessible live parts.
• Only qualified and trained personnel is allowed to perform installation and commissioning,
using appropriate tools and following the safety precautions given in this instruction. Make
sure that supply voltage has been switched off before installing and wiring.
• Drives are only allowed to be operated on TT, TN grounded industrial mains having
maximum 480V+10% line to line rms voltage, as specified in the user manual. Do not directly
install the drive on ungrounded (IT) or asymmetrically grounded mains. In case of
ungrounded mains, coupling with Dyn transformer with grounded secondary circuit is
necessary. Refer to drive technical data and wiring instruction.
• All the components used in the cabinet in which the drive is installed, (cables, contactors,
inductors and transformers, fuses, etc...), and the connected motor, must be in compliance
with the specification given in the product documentation, in addition to national regulations.
Make sure that the maximum temperature inside the cabinet does not exceed 45°C (113°F). If
necessary, use an appropriate air conditioning.
• The size and temperature rating of wires and cables used for connecting the drive must be in
compliance with the specification given in the instruction manual (see NEC 310-16 for USA).
Use also the specified tightening torque.
• Make sure about the correct drive-motor matching: voltage and current ratings must be
compatible.
• The user is responsible for over-current and short circuit protection of the drive. Read
carefully the specification given in the user manual.
