Version: 3.6
3.2
Special safety instructions for the AL38xx
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 AL3xxx 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 con-
nections to the motor when it is live. Under unfavorable conditions arcing may occur, re-
sulting 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 capac-
itors are discharged before touching live terminals. The voltage measured between the
DC+ and DC- terminals (X02) 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.
NOTE
Danger to the environment or devices
• Carefully read this manual before using the linear 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 linear servomotor.
• Only well trained, qualified electricians with sound knowledge of drive equipment may work on the de-
vice.
• Adhere without fail to the climatic conditions for the installation. Further information can be found in the
chapter Technical data and Mechanical installation.
• 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 harmonized standards and regulations required for implementation of this Directive in national
legislation.
NOTE
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 mag-
net yokes are particularly sensitive. Never let the magnet yokes fall on the floor.
