NOTE
1 See Chapter 3 for details of how to combine the power supply module, servo amplifier modules,
and spindle amplifier modules.
2 A magnetic contactor, AC line filter, regenerative discharge unit, and circuit breakers are always
required.
3 To protect the unit from surge currents caused by lightning, connect surge absorbers between
lines, and between the lines and ground, at the power inlet of the power magnetics cabinet.
See APPENDIX A for details.
4 When an insulating transformer is installed, high–frequency noise to the power supply is
reduced, so the AC line filter is not required. If the insulating transformer is installed outside
the power magnetics cabinet, and the cable connecting the amplifier is exposed, the cable must
be covered with a grounded metal duct, or an AC line filter must be installed.
