6.6  Wiring the Terminal Block 
Screw-type terminal blocks are used. The suitable wires are given below. 
 
 
NOTE
 
•  When removing the wire's insulation, be careful not to scratch the core wire. 
•  Do not twist the wires to connect them. 
•  Do not solder the wires to connect them. The solder may break due to 
vibration. 
•  After wiring, make sure stress is not applied to the wire. 
•  If the socket in the terminal block closes upon counter-clockwise rotation, 
the connection is wrong. Disconnect the wire, check the terminal hole, and 
then re-connect the wire.
