5.3 Wiring of power supply plug
Connect the power supply plug to the 24 VDC controller power supply according to instructions (1) (2) and
(3) and then, insert it into the CN1 connector of the controller.

Wiring of the power supply (C24V, M24V, 0V)
Connect the positive of the 24 VDC controller power supply of the controller to the C24V, M24V and EMG
terminal of the power supply connector, and connect the negative of that power supply to the 0V terminal.
Caution
For controller input power supply (24 VDC) use a power supply with a capacity not less than the
"momentary maximum power" of the electric actuator specification. Do not use "inrush current
restraining type" power supply.

Wiring of the stop switch (EMG)
By connecting 24V to EMG, motor becomes operable. Without connect the 24V to EMG, motor does not
move. Stop switch must be installed by the user to stop the electric actuator in abnormal situations.
Please refer to
"5.4 Stop circuits" P.25
for examples of how to wire stop switches.
Caution
The Servo is not ON unless a voltage of 24 VDC is applied to the EMG terminal.

Wiring of the lock release
(LK RLS)
Install an unlocking switch for adjustment or recovery during an emergency of the electric actuator with
lock. The switch (24 VDC, Contact capacity: 0.5A or more) should be obtained separately.
One terminal of the lock release switch should be connected to the 24 VDC power supply and the other
should be connected to the LK RLS terminal. When this is switched on, the lock will be released forcibly.
Caution
(1)If the electric actuator is a non-lock type, it is not necessary to wire the LK RLS terminal.
(2)Do not supply power to the LK RLS (lock release) during normal operation.
The 24 VDC supply to the LK RLS (lock release) is only required for the adjustment and the recovery in
the emergency.
After the wiring of the power supply plug is completed, connect it to the CN1 connector of the controller.
Please refer to
"5.3 Wiring of power supply plug" P.24
for how to wire the power supply plug.
