Cable Processing - Mitsubishi Electric MELSEC-Q Series User Manual

Cable Processing

Bare cables can be connected to the transmission cable terminal block; however, for safety reasons, it is
recommended to connect cables using bar solderless terminals.
For wiring, use the connection cables as listed in Page 20, Section 2.2.1 and tighten them with the applicable
tightening torque.
Use UL-listed solderless terminals and, for processing, use a tool recommended by their manufacturer.
[Recommended bar solderless terminals (manufactured by PHOENIX CONTACT GmbH & Co. KG)]
• For processing a 0.75 wire: AI 0,75-8 GY
• For processing a 1.25 wire: AI 1,5-8 BK
• For processing a 2 wire: Al 2,5-8 BU or others
• For processing two 0.75 wires: AI-TWIN 2  0,75-8 GY
• For processing two 1.25 wires: AI-TWIN 2  1,5-8 BK
When connecting two wires to one terminal, connect the two wires together to the TWIN bar solderless terminal.
When TWIN bar solderless terminals are used for this transmission cable terminal block, the maximum wire diameter
is 1.25.
For details on sizes other than those listed above and crimping tools, refer to the catalog or website of PHOENIX
CONTACT GmbH & Co. KG.
● Do not run multiple transmission cables (D, G) using a multicore cable. Running multiple transmission cables (D, G)
together may cause noise, resulting in a malfunction.
● Use the following line diameters for the transmission cables.
 200m or shorter: 0.75mm
 200m or longer: 0.9mm
● The voltage should not fall below the lower limit of the allowable voltage range due to the voltage drop caused by the
cable.
If the voltage falls below the lower limit, malfunctions may occur.
If the voltage falls substantially, install the external power supply.
For installing the external power supply, refer to the "AnyWire DB A20 Series Technical Manual" (manufactured by
Anywire Corporation).
● Do not connect soldered cables directly to the terminals. Doing so may loosen the screws, resulting in a poor contact.
● Use a crimping tool to connect a cable to a bar solderless terminal.
● Before inserting a bar solderless terminal, check the shapes of the wire insertion opening and bar solderless terminal.
Then, insert the terminal in the correct orientation. Inserting a bar solderless terminal wider than the wire insertion
opening may damage the terminal block.
