Preparations for Wiring
 Power Supply Wiring
• Be sure to use a dedicated line for power source.
• Be sure to earth this controller.
• Do not connect the earth wiring to those of gas pipe, water
pipe, lighting rod, telephone, etc.
 Type of wiring
• Use a fl exible wiring of 2 mm
• Use the standard power supply wiring for Europe (such as
H05RN-F or H07RN-F which conform to CENELEC (HAR)
rating specifi cations) or use the wiring based on IEC
standard (60245 IEC57, 60245 IEC66).
 Total Wire Length : 30 m or less
 Inter-Unit Control Wiring
 Type of wiring
• Use a fl exible shield wiring of 0.5 to 2 mm
• No polarity
 Total Wire Length : 1000 m or less
 Number of connectable units and devices :
(→ P.2 "Specifi cations")
Attention
• Ground the shield on both sides of shield wiring, otherwise an
operation error from noise may occur.

 Communication Adaptor Control Wiring
(When connecting a Communication Adaptor)
 Polarity (+/-) present
 Number of connectable Communication Adaptor: up to 7 units
 For the type of wiring and total wiring length,
see "Installation Instructions" supplied with the
Communication Adaptor.
 External I/O Wiring
(When connecting external equipment)
 Type of wiring
• Use a fl exible wiring of 0.5 to 2 mm
 Wire Length : 20 m or less
Attention
• When using the controller at a location susceptible to noise,
use a shield wiring.
 LAN Cable
 Type of wiring
• Category 5 or above straight cable
 Wire Length : 100 m or less

4. Wiring
Connect the power supply wiring.

 Connect the power supply wiring and the earth wiring to
the power supply terminal board and the earth terminal
board (on the sheet metal case) respectively.

*3: Use earth terminal board as protective earth
• Do not over-tighten. (The screw may be damaged.)
Connect the inter-unit control wiring.

 Connect the shield part of the shield wiring to No. 0 (FG
of the signal terminal board (TB2).
*4: Functional Ground
• Do not over-tighten. (The screw may be damaged.)
 There is no polarity.
Connect the Communication Adaptor control wiring.

the circuit breaker on.
• Before power on, measure the voltage of the power supply
terminal board, and check it for the specifi ed voltage.
Turning the power on with a voltage other than the
specifi ed one may blow the fuse. If this occurs, no power
