Press the terminal block into the CPU Unit, and tighten the M3 screws on the right and left
sides of the terminal block to mount it securely.
These screws are the self-raising screws, so you need to tighten the screws to connect the ter-
minal block.
Tighten the right and left screws alternately if they are hard to tighten.
If the terminal blocks are only pressed into positions, it is not fixed and electrical connection is
not ensured. Be sure to tighten the right and left screws firmly.
Tighten the screws to the torque of 0.5 N·m.
After you mount the terminal block, make sure that it is fixed to the Unit.
