BECKHOFF AL2000 Linear servomotor - Manual (Page 11)

Safety
3.2 Special safety instructions for the AL2xxx
The safety instructions are designed to avert danger and must be followed during installation,
commissioning, production, troubleshooting, maintenance and trial or test assemblies.
The linear servomotors from the AL2xxx series are not capable of running independently and are always
installed into 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!
• Negligent, improper handling of the linear servomotor and bypassing of the safety de­
vices can lead to personal injury or death through electric shock.
• It must be ensured that the protective conductor has been firmly connected.
• The machine manufacturer must prepare a hazard analysis for the machine, and must
take appropriate measures to ensure that unexpected movements cannot lead to injury
to persons or to objects.
• 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 oc­
cur, resulting in injury and damage to contacts.
• Disconnect the linear servomotor from the servo drive and secure it against reconnec­
tion before working on electrical parts with a voltage > 50 V.
• The DC link voltage of the servo drive may exceed 890 V
DC
. Wait until the DC link ca­
pacitors are discharged before touching live terminals. The voltage measured between
the DC+ and DC­ terminals (X02) of the AL2xxx must have dropped to below 50 V
DC
.
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 linear 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 to the environment or devices
• Carefully read this manual before using the linear servomotor thoroughly, paying partic­
ular attention to the safety instructions. In the event of any uncertainties please notify
your sales office immediately and refrain from working on the linear servomotor.
• Only well trained, qualified electricians with sound knowledge of drive equipment may
work on the device.
• Adhere without fail to the climatic conditions for the installation. Further information can
be found in the Technical data [ } 50] and Mechanical installation [ } 21] sections.
• If a linear 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 re­
quired for implementation of this Directive in national legislation.
Attention
Damage to the device due to inappropriate treatment
Treat the components of the linear servomotor with care, both in the packed and unpacked
state. The magnetic plates in particular are sensitive. Never let the magnetic plates fall on
the floor.
