Safety Precautions
Prior continuing …
•
make sure you have read and understood chapter “ PLEASE READ THIS FIRST” on page A-2,
•
do not engage with any work unless you possess the stated skills (
•
refer to
chapter “1.4 Symbols and Signs” on page 1-5 to understand the subsequently used
indicators,
•
you must observe any regulation applicable in the country and/or at the site of implementation
with regard to health and safety/accident prevention and/or environmental protection,
•
take note of the subsequently used indicators and follow them at all times.
Requirements
• Make sure that all associated devices and components are installed according to local regulations.
• Be aware that, by principle, an electronic apparatus can not be considered fail-safe. Therefore, you
must make sure that any machine/apparatus has been fitted with independent monitoring and safety
equipment. 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.
Best Practice
• For initial operation, make sure that the motor is free running. If not the case, mechanically discon-
nect the motor from the load.
Maximal permitted Supply Voltage
• Make sure that supply power is between 9…24 VDC.
• Supply voltages above 30 VDC will destroy the unit.
• Wrong polarity will destroy the unit.
Electrostatic Sensitive Device (ESD)
• Make sure to wear working cloth in compliance with ESD.
• Handle device with extra care.
Hot plugging the USB interface may cause hardware damage
If the USB interface is being hot-plugged (connecting while the power supply is on), the possibly high
potential differences of the two power supplies of controller and PC/Notebook can lead to damaged
hardware.
• Avoid potential differences between the power supply of controller and PC/Notebook or, if possible,
balance them.
• Insert the USB connector first, then switch on the power supply of the controller.
DANGER
High Voltage and/or Electrical Shock
Touching live wires causes death or serious injuries!
• Consider any power cable as connected to live power, unless having proven the opposite!
• Make sure that neither end of cable is connected to live power!
• Make sure that power source cannot be engaged while work is in process!
• Obey lock-out/tag-out procedures!
• Make sure to securely lock any power engaging equipment against unintentional engagement and
tag with your name!
