Note 1. When using stranded wire, be sure to avoid stray wire strands that might
short-circuit an adjacent terminal.
2. Do not solder the ends of stranded wires. Solder can break and cause wiring
problems. Also, the solder can cause corrosion on the contact surface.
3. Be sure to use the correct pin allocation when assembling and wiring con-
nectors or terminal blocks.
Use the following procedure when wiring a terminal block.
1, 2, 3... 1. Use a flatblade screwdriver to loosen the screws at the left and right sides of
the terminal block.
