20 Safety instructions
• Make sure that debris from drilling, cutting and grinding does not go into the
drive during installation. Electrically conductive debris inside the drive can cause
damage or malfunction.
• Make sure that there is sufficient cooling. See the technical data.
• Keep the cabinet doors closed when the drive is powered. With the doors open,
a risk of a potentially fatal electric shock, arc flash or high-energy arc blast exists.
If you cannot avoid working on a powered drive, obey the local laws and regulations
on live working (including – but not limited to – electric shock and arc protection).
• Before you adjust the drive operation limits, make sure that the motor and all
driven equipment can operate throughout the set operation limits.
• Before you activate the automatic fault reset or automatic restart functions of
the drive control program, make sure that no dangerous situations can occur.
These functions reset the drive automatically and continue operation after a fault
or supply break. If these functions are activated, the installation must be clearly
marked as defined in IEC/EN/UL 61800-5-1, subclause 6.5.3, for example, "THIS
MACHINE STARTS AUTOMATICALLY".
• The maximum number of drive power-ups is five in ten minutes. Too frequent
power-ups can damage the charging circuit of the DC capacitors.
• If you have connected safety circuits to the drive (for example, Safe torque off or
emergency stop), validate them at start-up. See separate instructions for the
safety circuits.
• Beware of hot air exiting from the air outlets.
• Do not cover the air inlet or outlet when the drive is running.
Note:
• If you select an external source for the start command and it is on, the drive will
start immediately after fault reset unless you configure the drive for pulse start.
See the firmware manual.
• If the drive is in remote control mode, you cannot stop or start the drive with the
control panel.
• Only authorized persons are allowed to repair a malfunctioning drive.
