Caution
<Precautions when laying power wiring>
Use round pressure terminals for connections to the power terminal block.
When none are available, follow the instructions below.
!
Do not connect wiring of different thicknesses to the power terminal block. (Slack in the
power wiring may cause abnormal heat.)
!
When connecting wiring which is the same thickness, do as shown in the figure below.
!
For wiring, use the designated power wire and connect firmly, then secure to prevent outside
pressure being exerted on the terminal board.
!
Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small
head will strip the head and make proper tightening impossible.
!
Over-tightening the terminal screws may break them.
!
See the table below for tightening torque for the terminal screws.
<Precautions when connecting the ground>
When pulling the ground wire out, wire it so that it comes through the cut out section of the cup
washer. (An improper ground connection may prevent a good ground from being achieved.)
