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.
