WIRING
(3)
Insert the wires into a socket.
O Wire removal
Pull the wire while pushing the open/close button all the way down firmly with a flathead screwdriver.
CAUTION
O When using stranded wires without a blade terminal, twist enough to avoid short circuit with a nearby terminals or wires.
O Pulling out the wire forcefully without pushing the open/close button all the way down may damage the terminal block.
O Use a small flathead screwdriver (tip thickness: 0.4 mm, tip width: 2.5 mm). If a flathead screwdriver with a narrow tip is used,
terminal block may be damaged. Commercially available products (as of February 2016).

O Place the flathead screwdriver vertical to the open/close button. In case the blade tip slips, it may cause an inverter damage or
injury.
2.4.3 Wiring precautions
O It is recommended to use the cables of 0.3 to 0.75 mm² gauge for connection to the control circuit terminals.
O The wiring length should be 30 m (200 m for the terminal FM) maximum.
O Use two or more parallel micro-signal contacts or twin
contacts to prevent a contact faults when using contact
inputs since the control circuit input signals are micro-
currents.
O To suppress EMI, use shielded or twisted cables for the
control circuit terminals and run them away from the main
and power circuits (including the 200 V relay sequence
circuit). For the cables connected to the control circuit
terminals, connect their shields to the common terminal of
the connected control circuit terminal. When connecting an external power supply to the terminal PC, however, connect the
shield of the power supply cable to the negative side of the external power supply. Do not directly earth (ground) the shield to
the enclosure, etc.
O Always apply a voltage to the alarm output terminals (A1, B1, C1, A2, B2, C2) via a relay coil, lamp, etc.
O When using an external power supply for transistor output, note the following points to prevent a malfunction caused by
undesirable current.
Do not connect a terminal SD on the inverter and the 0 V terminal of the external power supply (when the sink logic is selected).
Do not connect a terminal PC on the inverter and the +24 V terminal of the external power supply (when the source logic is
selected).
Do not install an external power source in parallel with the internal 24 V DC power source (connected to terminals PC and SD) to
use them together.
Refer to Chapter 2 of the Instruction Manual (Detailed) for the detail.
O Separate the wiring of the control circuit away from the wiring of the main circuit.
