Grounding Instructions
WARNING:
Be sure the system is properly grounded before applying power. Do not apply power before
you ensure that grounds are connected. Electrical shock can cause serious or fatal injury.
Follow the National Electrical Code (NEC) and local codes for the safe installation of this
equipment.
1.
All grounded, cord–connected dust control units:
In the event of a malfunction or breakdown, grounding provides a path of least
resistance for electric current to reduce the risk of electric shock. This dust control unit is
equipped with an electric cord having an equipment–grounding conductor and a
grounding plug. The plug must be plugged into a matching outlet that is properly
installed and grounded in accordance with all local codes and ordinances. Do not
modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a
qualified electrician.
Improper connection of the equipment–grounding conductor can result in a risk of
electric shock. The “Green” insulated wire (with or without yellow stripes) is the
equipment–grounding conductor. If repair or replacement of the electric cord is
necessary, do not connect the equipment–grounding conductor to a live terminal. Check
with a qualified electrician or serviceman if the grounding instructions are not completely
understood, or if in doubt as to whether the tool is properly grounded.
Use only 3–wire extension cords that have 3–prong grounding plugs and 3–pole
receptacles that accept the tool’s plug.
Repair or replace damaged or worn cord immediately.
2. Grounded,
cord–connected dust control units intended for use on a supply circuit having
a nominal rating less than 150 volts:
This dust control unit is intended for use on a circuit that has an outlet that looks like the
one illustrated n Figure A. The tool has a grounding plug that looks like the plug
illustrated in Figure A. A temporary adapter, which looks like the adapter illustrated in
Figures B and C, may be used (except in Canada) to connect this plug to a 2–pole
receptacle as shown in Figure B if a properly grounded outlet is not available. The
temporary adapter should be used only until a properly grounded outlet can be installed
by a qualified electrician. The green–colored rigid ear, lug, etc. extending from the
adapter must be connected to a permanent ground such as a properly grounded outlet
box.
3.
Permanently connected dust control units:
This dust control unit should be connected to a grounded, metal, permanent wiring
system; or to a system having an equipment–grounding conductor.
