14 Safety instructions
General safety in installation, start-up and maintenance
These instructions are for all personnel that install the drive and do maintenance work
on it.
WARNING! Obey these instructions. If you ignore them, injury or death, or
damage to the equipment can occur.
•Handle the drive carefully.
• Use safety shoes with a metal toe cap to avoid foot injury.
• Keep the drive in its package or protect it otherwise from dust and burr from
drilling and grinding until you install it.
• Protect also the installed drive against dust and burr. Electrically conductive
debris inside the drive may cause damage or malfunction.
• Vacuum clean the area below the drive before the start-up to prevent the drive
cooling fan from drawing the dust inside the drive.
• Do not cover the air inlet and outlet when the drive runs.
• Make sure that there is sufficient cooling. For more information, see section
Cooling and degrees of protection on page 39.
• Before you connect voltage to the drive, make sure that the drive covers are on.
Keep the covers on during the operation.
• Before you adjust the drive operation limits, make sure that the motor and all
driven equipment can operate throughout the set operation limits.
• The maximum number of drive power-ups is two in one minute. Too frequent
power-ups can damage the charging circuit of the DC capacitors. The maximum
number of times the circuit can charge is: 1 million times for all frames.
If you have connected safety circuits to the drive (for example, emergency stop and
Safe torque off), validate them at the start up.
Note:
• If you select an external source for start command and it is On, the drive starts
immediately after fault reset.
• When the control location is not set to Local, the stop key on the control panel will
not stop the drive.
Drives can be repaired only by an authorized person.
