Strong magnetic field
The high magnetic forces produced by the device constitute an imminent hazard to persons wearing a car-
diac pacemaker or metal implants.
All persons who possibly may suffer impairment caused by strong magnetic fields must not approach the
device and must stay clear and in a safe distance of at least two (2) meters.
General rules
• Make sure that all associated devices and components are installed according to local regulations.
• Be aware that, by principle, an electronic apparatus cannot be considered fail-safe. Therefore, you must
make sure that any machine/apparatus has been fitted with independent monitoring and safety equip-
ment. If the machine/apparatus should break down, if it is operated incorrectly, if the control unit breaks
down or if the cables break or get disconnected, etc., the complete drive system must return—and be
kept—in a safe operating mode.
• Be aware that you are not entitled to perform any repair on components supplied by maxon motor.
Electrostatic Sensitive Device (ESD)
• Wear electrically conductive clothing and footwear.
• Observe ESD protective measures.
WARNING
Strong magnetic field
High magnetic force can cause serious injuries!
• Keep stator and rotor mechanically blocked at all times! Do so by using a mechanical locking device,
a mounting aid, or non-magnetic spacers!
• Make sure to remove/keep clear any metal parts or metallic items—also such as cardiac pacemakers,
implants, watches, bracelets, credit cards, mobile phones, etc—before you approach the motor!
• Use only non-magnetic tools when you work on the motor or in its vicinity!
• Put up warning signs stating STRONG MAGNETIC FIELDS around the installation area and at the
storage location!
• Inform persons around of the potential danger. Instruct them accordingly and request them to follow
the precautionary measures!
WARNING
Pinching and shearing risk
Sudden movement and shift of the rotor can cause serious injuries!
To prevent sudden shift during installation you must keep both stator and rotor blocked at all times. Do
so by using a mechanical locking device, a mounting aid, or non-magnetic spacers!
