2 Subject to technical amendments BU0560_ERS_GB-0512
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:
The 7-pin Phoenix spring terminal bar X9 (CAN plug) is used instead of the two RJ45 plug connectors (from
SK 520E).
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 nd
quarter 2012), the WAGO spring terminal bar will be used. Detailed information in this context
are illustrated at the former edition of the BU0560.
