WIRING
(3) Insert the wires into a socket.
CAUTION
l When using stranded wires without a blade terminal, twist enough to avoid short circuit with a nearby terminals or wires.
l Lead the wires through the holes for wiring. (For the details of the holes for wiring, refer to the FR-F800 Instruction Manual
(Detailed).)
l Place the flathead screwdriver vertical to the open/close button. In case the blade tip slips, it may cause an inverter damage or
injury.
l Wire removal
Pull the wire while pushing the open/close button all the way down firmly with a flathead screwdriver.
CAUTION
l Pulling out the wire forcefully without pushing the open/close button all the way down may damage the terminal block.
l 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).

l 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
l Terminals PC, 5, and SD are all common terminals (0 V) for I/O signals. Do not earth them.
l Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and power
circuits (including the 230 V relay sequence circuit).
l It is recommended to use the cables of 0.3 to 0.75 mm² gauge for connection to the control circuit terminals.
l The wiring length should be 30 m (200 m for the terminal FM) maximum.
l Use two or more parallel micro-signal contacts or twin
contacts to prevent contact faults when using contact inputs
since the control circuit input signals are micro-currents.
l Always apply a voltage to the fault output terminals (A1, B1,
C1, A2, B2, C2) via a relay coil, lamp, etc.
l Do not short terminal PC and SD. Inverter may be damaged.
l When using an external power supply for transistor output,
note the following points to prevent a malfunction caused
by undesirable current.
l Do not connect terminal PC on the inverter and the +24 V terminal of the external power supply (when the source logic is
selected).
l Do not connect any terminal SD on the inverter and the 0 V terminal of the external power supply (when the sink logic is
selected).
l 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.
