Electrical Safety In Installation, Start-Up And Maintenance; Electrical Safety Precautions - ABB ACS580-07 Hardware Manual

16 Safety instructions
• Vacuum clean the area around the drive before the start-up to prevent the drive cooling
fan from drawing the dust inside the drive.
• 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
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.
• Validate any safety circuits (for example, Safe torque off or emergency stop) in 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.
• Depending on the wiring and parametrization of the drive, the stop key on the control
panel may not stop the drive.
• Only authorized persons are allowed to repair a malfunctioning drive.

Electrical safety precautions

These electrical safety precautions are for all personnel who do work on the drive, motor
cable or motor.
WARNING!
Obey these instructions. If you ignore them, injury or death, or damage to the
equipment can occur. If you are not a qualified electrician, do not do installation
or maintenance work. Go through these steps before you begin any installation or
maintenance work.
1. 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.
2. Clearly identify the work location.
3. Disconnect all possible voltage sources.
• Open the main disconnecting device of the drive.
• Open the charging switch if present.
• Open the auxiliary voltage switch-disconnector (if present), and all other possible
disconnecting devices that isolate the drive from dangerous voltage sources.
