(1) Hex nut
(2) Ring terminal
(3) Grounding post
(4) Grounding strip
NOTE:
NEC recommends that you use the primary grounding point or auxiliary grounding point 1, because the
grounding cable and grounding screw provided with the switch are applicable only to these two grounding
points.
To use auxiliary grounding point 2 on QX-S6632QP, prepare a grounding cable yourself. The connection
method is the same as connecting to the other two grounding points.
3.2.2 Grounding the switch by using the AC power cord
If the installation site has no grounding strips, you can ground an AC-powered switch
through the protective earth (PE) wire of the power cord, but must make sure:
The power cord has a PE terminal.
The ground contact in the power outlet is securely connected to the ground in the
power distribution room or on the AC transformer side.
The power cord is securely connected to the power outlet.
