Earth the backplate to the star point (G).
The 890 must be mounted inside a cubicle complying with the European safety standards
VDE 0160/EN50178.
Control terminals are SELV (Safe Extra Low Voltage), i.e. double-insulated from power
circuits. 0.08mm 2 (28AWG) to 2.5mm
This must be insulated from the back panel. It is used for all power earths.
Refer to Chapter 5: "Associated Equipment" for the specified filter. This may help to
achieve EMC compliance. Refer to Appendix C.
The star point connects all earth busbars. Connect the star point to the incoming safety
earth (PE). Note the possible requirement for PE2 connections to each drive, refer to page
4-25.
External brake resistors are available. Refer to Chapter 5: "Associated Equipment".
Ensure wiring is rated for highest system voltage.
A very fast external bus (IEEE 1394a) to connect up to 63 units. You will need the
