Intended use of the frequency inverter
Compliance with the operating instructions is necessary for fault-free operation and the acceptance of
possible warranty claims. These operating instructions must be read before working with the device!
The BU0560 contains important information on servicing and must be kept near to the device.
The CANopen modules and the corresponding frequency inverters are devices for stationary installation
in control cabinets or decentralised structures. All data regarding technical data and permissible
conditions at the installation site must be complied with.
Commissioning (commencement of the intended use) is not permitted until it has been ensured that the
machine complies with the EMC Directive 2004/108/EEC and that the conformity of the end product
meets the Machinery Directive 2006/42/EEC (observe EN 60204).

NORDAC SK 500E - ERS Information Bus connection
This supplement contains excerpts from the manual BU 0500 EN with supplementary entries for the plug-in
CAN/CANopen connection. This is additional information for the SK 500E-xxx-xxx-A-ERS special device series
with a plug-in 7-pin CAN spring terminal bar.
All other information should be obtained from the frequency inverter manual BU0500. For detailed CAN
information, please refer to the operating instructions BU0060 or contact the supplier of the frequency inverter.
Contact assignment of the X9 CAN terminal strip:
X9: for connection to the CAN/
CANopen interface
only SK 500E- … -ERS
DIP switch 1/2:
1 Termination resistor RJ12 for
RS485 interface
2 Termination resistor for
CAN /CANopen interface
ON = connected
The 7-pin Phoenix spring terminal bar X9 (CAN plug) is used instead of the two RJ45 plug connectors (from
SK 520E).
X9: [75] CAN-H
[45] +24 V -Ex
[75] CAN-H
[90] Shield
[76] CAN-L
[46] GND-Ex
[76] CAN-L
Terminals 75 and 76 on the spring terminal bar X9 are for connection of the signal leads from CAN High and
CAN Low and are doubled for looping.
NOTE
Until date of bringing the Phoenix spring terminal bar onto the market (approx. the end of the 2
quarter 2012), the WAGO spring terminal bar will be used. Detailed information in this context
are illustrated at the former edition of the BU0560.
