Wiring/Piping Diagram (Arm Length: 300/350)
Notes (1) The actual layout of board connectors varies from this drawing. (2) Since the brake power circuit is provided on the primary side (high-voltage side), a dedicated 24 V power supply is
required for this circuit. The 24 V power supply for I/O circuits used on the secondary side (low-voltage side) cannot be
shared.
(3) To operate the alarm LED, the user must provide a circuit that uses the controller I/O output signal.
