3.2 Special safety instructions for AM3000 and AM3500
The safety instructions are designed to avert danger and must be followed during installation, commissioning,
production, troubleshooting, maintenance and trial or test assemblies.
The servomotors of the AM3000 and AM3500 series are not designed for stand-alone operation and are always
installed in a machine or system. After installation the additional documentation and safety instructions provided
by the machine manufacturer must be read and followed.
WARNING
Serious risk of injury through high electrical voltage!
• Never open the servomotor when it is live. The measured voltage between terminals U, V
and W must have dropped below 50 V. Opening the device would invalidate any warranty
and liability claims against Beckhoff Automation GmbH & Co. KG.
• Negligent, improper handling of the servomotor and bypassing of the safety devices can lead
to personal injury or death through electric shock.
• Ensure that the protective conductor is connected properly.
• The machine manufacturer must prepare a hazard analysis for the machine, and must take
appropriate measures to ensure that unexpected movements can not lead to injury to
persons or to material damage.
• Power leads may be live, even if the motor is not running. Never undo the electrical
connections to the motor when it is live. Under unfavourable conditions arcing may occur,
resulting in injury and damage to contacts.
• Disconnect the servomotor from the servo drive and secure it against reconnection before
working on electrical parts with a voltage > 50 V.
• The DC link voltage of the servo drive may exceed 890 V. Wait until the DC link capacitors
are discharged before touching live terminals. The measured voltage between terminals DC+
and DC- (X02) must have dropped below 50 V.
WARNING
Serious risk of injury through hot surfaces!
• The surface temperature may exceed 50 °C, resulting in a risk of burns.
• Avoid touching the housing during or shortly after operation.
• Leave the servomotor to cool down for at least 15 minutes after it is switched off.
• Use a thermometer to check whether the surface has cooled down sufficiently.
Attention
Danger for persons, the environment or equipment
• Carefully read this manual before using the servomotor thoroughly, paying particular
attention to the safety instructions. In the event of any uncertainties please notify your sales
office immediately and refrain from working on the servomotor.
• Only well trained, qualified electricians with sound knowledge of drive equipment may work
on the device.
• During installation it is essential to ensure that the specified ventilation clearances and
climatic conditions are adhered to. Further information can be found in the "Technical data"
and "Mechanical installation" sections.
• If a servomotor is installed in a machine it must not be commissioned until proof of
compliance of the machine with the latest version of the EC Machinery Directive has been
provided. This includes all relevant harmonised standards and regulations required for
implementation of this Directive in national legislation.
