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.
• Keep the drive in its package or protect it otherwise from dust and burr from
drilling and grinding until you install it.
• Vacuum clean the area below the drive before the start-up to prevent the drive
cooling fan from drawing the dust inside the drive.
• Protect also the installed drive against dust and burr. Electrically conductive
debris inside the drive may cause damage or malfunction.
• Do not cover the air inlet and outlet when the drive runs.
• Make sure that there is sufficient cooling.
• Before you connect voltage to the drive, make sure that the drive covers are on.
Keep the covers on during operation.
• 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 automatic fault reset 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. 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 two per minute. Too frequent power-
ups can damage the charging circuit of the DC capacitors. The maximum total
number of chargings is 15000.
• 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 will start
immediately after a fault reset, unless you configure the drive for pulse start.
• When the control location is not set to local, the stop key on the control panel
does not stop the drive.
• Drives can be repaired only by an authorized person.
