1.7.2

Control circuit terminal layout

Terminal screw size : M3.5
Tightening torque
: 1.2N·m
When connecting three or more control cables
to the terminal 5, connect the accessory
terminal 5 dedicated L-shaped jumper to the
terminal 5.
In this case no cable should be connected to
the screw in the
part.
1.7.3

Wiring instructions

1)
Terminals 5, SD and SE are common to the I/O signals and isolated from each other. Do not ground these ter-
minals. Avoid connecting the terminal SD and 5 and the terminal SE and 5.
2)
Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main
and power circuits (including the 200V relay sequence circuit).
3)
Since the control circuit input signals are micro currents, use two or more parallel micro signal contacts or a
twin contact to prevent a contact fault.
4)
It is recommended to use the cables of 0.75mm
cable gauge used is 1.25mm
cables are run improperly, resulting in an operation panel or parameter unit contact fault.
5)
The maximum wiring length should be 30m (98.43 feet).
1.7.4

Connecting the control circuit to a power supply separately from the main circuit

If the magnetic contactor (MC) in the inverter power supply is opened when the protective circuit is operated, the
inverter control circuit power is lost and the alarm output signal cannot be kept on. To keep the alarm signal on
terminals R1 and S1 are available. In this case, connect the power supply terminals R1 and S1 of the control circuit
to the primary side of the MC.

CAUTION
1. When the main circuit power (R, S, T) is on, do not switch off the control power (terminals R1, S1).
Otherwise the inverter may be damaged.
2. When using a separate power supply, the jumpers across R-R1 and S-S1 must be removed.
Otherwise the inverter may be damaged.
3. For a different power supply system which takes the power of the control circuit from other than the
primary side of the MC, the voltage should be equal to the main circuit voltage.
4. The power supply cables must not be connected to the lower terminals. If connected, the inverter
may be damaged.
5. Entering the start signal with power supplied to only the R1 and S1 terminals will result in an error
display (E.OC1).
