NOTE
1 For the control power supply, single–phase
200VAC is required.
2 See Chapter 4 for details of how to combine the
power supply module, servo amplifier modules, and
spindle amplifier modules.
3 A magnetic contactor, AC line filter, and circuit
breakers are always required.
4 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 magnetic cabinet. See
APPENDIX A for details.
5 Measures must be taken to detect the operation
(trip) of circuit breaker 3.
