NOTE
1 Always install the circuit breakers, magnetic contactor, and AC reactor.
2 To protect the equipment from lightning surge voltages, install a lightning surge protector across
each pair of power lines and across each power line and the grounding line at the power inlet
of the power magnetics cabinet. See Appendix A for details.
3 Always connect the control power supply cable to the CX1A. If it is connected to the CX1B,
fuses inside the unit may blow.
4 See Section 5.2.3 for the type of the cable to be used for making a connection to a frame
ground.
5 Using a fan adapter in the SPM–11 requires cable K4 (across the CX1B and CX1A).
6 Provide a means of detecting whether circuit breaker 3 has tripped.
