ATTEMTION! Requirements for longer cables
• Use only the ready made-up cables supplied for the DC electrical connec-
tions between the devices.
• If extending the cable is unavoidable (such as to bypass a switch cabinet
panel or for a second DC-AC servo drive array), the DC link connection
must be made as follows:
− Cable cross-section >30mm² (copperr)
− A PE conductor of the same cross-section should run alongside and be
connected to the PE terminals of the two interconnected devices.
− The three conductors (DC+, DC-, PE) should be bundled and shielded.
− A length of 2 metres must not be exceeded.
− Only one extension may be executed in each multi-axis system.
