Improper installation of the grounding plug is able to result in a risk of electric shock.
When repair or replacement of the cord or plug is required, do not connect the
grounding wire to either flat blade terminal. The wire with insulation having an outer
surface that is green with or without yellow stripes is the grounding wire.
Check with a qualified electrician or serviceman when the grounding instructions are
not completely understood, or when in doubt as to whether the product is properly
grounded. Do not modify the plug provided; if it does not fit the outlet, have the proper
outlet installed by a qualified electrician.
This pump must be connected to a grounded, metallic, permanent wiring system, or an
equipment-grounding terminal or lead on the product.

Unplug-preventive hardware
（
Option
）
Whenever you may operate the vacuum pump with your power cable,
provide it with the unplug-preventive hardware, which should be
selected so as to fit the shape of the power cable.
The unplug-preventive hardware allows you to secure the power cable
so that the motor may not accidentally have it unplugged.
For a procedure for installing the unplug-preventive hardware, refer to
“a-2 How to Install Unplug-preventive Hardware.”
