Safety instructions 15
All frames;
• Beware of hot surfaces. Some parts, such as heatsinks of power semiconductors,
remain hot for a while after disconnection of the electrical supply.
• Beware of hot air exiting from the air outlets.
• 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 can 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 is running.
• Make sure that there is sufficient cooling. See section Examining the installation site
(page 55).
• 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 connect voltage to the drive, make sure that the cabinet doors are closed.
Keep the doors closed 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 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
• To prevent the drive module from falling, attach its top lifting lugs with chains to the cabinet
frame before you push the module into the cabinet and pull it from the cabinet. Work carefully
preferably with help from another person. Keep a constant pressure with one foot on the base
of the module to prevent the module from falling on its back.
