NSTALLATION
The EPOS4 50/5

Directive 2006/42/EC, Article 2, Clause (g) and
is intended to be incorporated into or assembled
with other machinery or other partly completed machinery or equipment
.
3.1
Generally applicable Rules
Maximal permitted supply voltage
• Make sure that supply power is between 10…50 VDC.
• Supply voltages above 56 VDC, or wrong polarity will destroy the unit.
• Note that the necessary output current is depending on the load torque. Yet, the output current limits
are as follows:
– continuous max. 5 A
– short-time (acceleration) max. 15 A
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.
Hot plugging/hot swapping the extension slots may cause hardware damage
Switch off the controller’s power supply before removing or inserting an extension card.
WARNING
Risk of injury
Operating the device without the full compliance of the surrounding system with the EU Direc-
tive 2006/42/EC may cause serious injuries!
• Do not operate the device, unless you have made completely sure that the other machinery fully
complies with the EU directive’s requirements!
• Do not operate the device, unless the other machinery fulfills all relevant health and safety
aspects!
• Do not operate the device, unless all respective interfaces have been established and fulfill the
requirements stated in this document!
