•
Do not perform wiring with power supplied to the Switch. Do not
touch the terminals or other charged parts of the Switch while
power is being supplied. Doing so may result in electric shock.
•
After wiring the Switch, ensure an appropriate insulating distance.
Wiring
•
Twist the conductors through the terminal holes before soldering.
To perform soldering on solder terminals, use a soldering iron with
a capacity of 60
W
maximum and complete soldering within 5
seconds.
Wait
for one minute after soldering before exerting any
external force on the solder.
•
For connection with tab terminals, gently insert receptacles for
#187 tabs in the terminal push-out direction.
The Switch does not have a ground terminal.
Panel Mounting
Tighten the hexagonal nut using a wrench while securing the Switch
by holding it with your fingers.
