PREREQUISITES FOR PERMISSION TO COMMENCE INSTALLATION
The EPOS2 Motherboard is considered as partly completed machinery according to EU directive 2006/
42/EC, Article 2, Clause (g) and therefore is intended to be incorporated into or assembled with
other machinery or other partly completed machinery or equipment.
You must not put the device into service, …
• unless you have made completely sure that the other machinery – the surrounding system the device
is intended to be incorporated to – fully complies with the requirements stated in EU directive 2006/
42/EC!
• unless the surrounding system fulfills all relevant health and safety aspects!
• unless all respective interfaces have been established and fulfill the stated requirements!

2Introduction
The EPOS2 Motherboard (document identifier is “EPOS2 Module 36/2 MoBo”) offers a smart way to
connect an EPOS2 Module 36/2 positioning controller in a space-saving manner while reducing wiring
effort to an absolute minimum.
The individual EPOS2 Motherboard originates from an eleven-partite array allowing the integration of an
eleven axis system in one single shot. It can easily be cracked along predetermined breaking lines and
is scalable to suit your specific needs.
Remark
Note that the order number 407582 comprises one EPOS2 Motherboard suitable to carry one EPOS2
Module 36/2.
If you wish to order an array of motherboards (up to 11 as one part), you will be required to order the
respective number of EPOS2 Motherboards (407582).
The present document provides you with information on how to employ the EPOS2 Motherboard. It
describes the standard procedure when putting the device into operation and is meant to facilitate instal-
lation and configuration of a multiple axis system comprising up to eleven EPOS2 Module 36/2.
Find the latest edition of the present document, as well as additional documentation and software to the
EPOS2 Motherboard also on the Internet: www.maxonmotor.com

2.3 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 (chapter “1.2 Target Audi-
ence” on page 1-5),
• refer to chapter “1.4 Symbols and Signs” on page 1-6 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 11…36 VDC.
• Supply voltages above 40 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.
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!

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.

3 Motherboard (407582)
The EPOS2 Motherboard connects an individual EPOS2 Module 36/2 positioning controller. Further-
more, the motherboard is available as an eleven-partite array capable to integrate up to eleven axis with
the least effort possible. It can easily be cracked along predetermined breaking lines to the desired scale
of your system.
The following information describes both types of use:
• Setup of a motherboard to receive one EPOS2 Module 36/2.
• Use of an motherboard array to receive up to eleven EPOS2 Module 36/2s.
