[Wiring for products with electric energy pulse output]

Caution

[Wiring for products with CC-Link communication]

Caution

Danger

●

 The 114 and 113 pulse output terminals are included with MDUs with electric energy pulse output.

●

 The pulse output line forms a small-signal circuit. Install it at least 10 cm away from strong circuits. The wiring length is determined by various 

conditions such as the anti-noise performance of the pulse receiver. However, the wiring should not exceed 100 m.

●

 If using A/C for the pulse output power supply, make sure that the pulse receiver does not erroneously operate due to leak current caused by 

conduit capacitance.

●

 CC-Link communication terminals DA, DB, DG, and SLD are included with CC-Link communication MDUs.
Connect these to the CC-Link transmission line. Never connect non-transmission line terminals (such as the L1 and L2 control power supply 

terminals).

The CC-Link transmission line forms a small-signal circuit. Connecting it improperly is extremely dangerous.

●

 The CC-Link transmission line forms a small-signal circuit. Install it at least 10 cm away from strong circuits.

However, install it at least 30 cm away if parallel for a long distance.

●

 If installing a MDU main unit with CC-Link communication, a hole cannot be made in the face board. Making a hole in the face board will leave 

a gap in the CC-Link communication cable wiring.

[Wiring for products with MODBUS communication]

Caution

Danger

●

 MODBUS communication terminals FG, SLD, 485+, 485-, Ter are included with MODBUS communication MDUs.
Connect these to the MODBUS transmission line. Never connect non-transmission line terminals (such as the 

L1

 and L2 control power supply 

terminals).

The MODBUS transmission line forms a small-signal circuit. Connecting it improperly is extremely dangerous.

●

 The MODBUS transmission line forms a small-signal circuit. Install it at least 10 cm away from strong circuits.

However, install it at least 30 cm away if parallel for a long distance.

● 

If installing a MDU main unit with MODBUS communication, a hole cannot be made in the face board. Making a hole in the face board will leave 
a gap in the MODBUS communication cable wiring.
