How to connect to terminal plate
When cables (wires) are connected to the terminal plate inside the main unit, use the dedicated
screwdriver or a compatible flathead screwdriver.
When connecting a stranded wire, be sure to press the push button and open the spring while connecting
the wire.
1
Push the push button straight
downward using the
compatible screwdriver or
equivalent to open the spring.
2
Insert a wire with a specified
bare wire length (10 mm) until
the end of it reaches the
deepest point.
3
Release the screwdriver.
The wire is connected.
CAUTION
Never fail to use the correct tool.
Do not insert more than one wire into one wiring hole. If the total size (mm
2
) of two or more wires is
within the maximum wire connection range of the terminal plate, it may cause reduced spring
clamping force, defective insulation due to clogged wire sheath, defective contact or coming off of
wires.
