Wiring To A Spring Clamp Terminal Block - Mitsubishi Electric MELSEC iQ-R Series Configuration Manual

Wiring to a spring clamp terminal block

This section describes the wiring to a spring clamp terminal block.
Wiring method
■ Connecting a cable
(1)
(3)
■ Disconnecting a cable
Securely insert the spring clamp terminal block tool to the Q6TE-18SN tool insertion opening (square hole) deeply and
straight, and pull out the bar solderless terminal or cable.
Wiring precautions
• Insert only one wire into the circular shaped hole of the spring clamp terminal block. Inserting two or more wires may result
in a poor contact to the terminal part.
• For the wire strip length, satisfy the specifications in this manual. Failure to do so may result in electric shock or short circuit
between adjacent terminals because the conductive part. If the wire strip length is too short, it may result in the poor contact
to the spring clamp terminal part.
• Do not use the wire soldered the head. Poor contact or insertion-extraction failure to the spring clamp terminal block may
occur because of the difference of the solder processing result.
• There will be clearances between adjacent modules when the extended temperature range base unit is used, and therefore
care should be taken to ensure that cables do not pass between units at wiring.
Precautions for using a spring clamp terminal block tool
Observe the following precautions for using a spring clamp terminal block tool. Failure to do so may result in the damage to
the spring clamp terminal part or resin part of the terminal block.
• Use the dedicated spring clamp terminal block tool.
• Do not insert a bar solderless terminal or cable before inserting the spring clamp terminal block tool to the tool insertion
opening.
• Insert the spring clamp terminal block tool to the tool insertion opening straight.

1.
Securely insert a spring clamp terminal block tool (2) to
the Q6TE-18SN tool insertion opening (square hole) (1)
deeply and straight.
2.
Insert a cable or bar solderless terminal to the wire
insertion opening (round hole) (3) and pull out the spring
clamp terminal block tool.
3.
Pull the cable or bar solderless terminal lightly, check
that it is clamped securely.
