Note: Wire the system to comply to National Electrical Code.

Connect the alarm output (ALM) terminals for the three servo amplifiers in series
to enable alarm detection relay 1RY to operate. The output transistor is turned
OFF when the ALM output signal enters an alarm state.
Multiple servos can share a single MCCB or noise filter. Always select an
MCCB or noise filter that has enough capacity for the total power capacity (load
conditions) of those servos. For details, refer to B.1. Wiring Precautions.
