5.0 GROUNDING INSTRUCTIONS
This vacuum cleaner must be properly grounded. If it should malfunction or
breakdown, grounding provides a path of least resistance for electric current to
reduce the risk of electric shock. This vacuum cleaner is equipped with a cord
having an equipment-grounding conductor. The explosion proof vacuum cleaner is
supplied without an electrical plug. It is the user’s responsibility to install a suitable
plug certified for the hazardous locations area classification.
The explosion proof plug should be installed by a qualified electrician only. The plug
must be plugged into an appropriate outlet that is properly installed and grounded in
accordance with all local codes and ordinances. Ensure that the fuse/breaker on the
electrical panel is of the correct rating and exceeds the maximum current rating
shown on the technical data sticker of the vacuum unit. Test the electrical continuity
of the vacuum cleaner prior to each use (see section 6: testing for ground
continuity).

This vacuum cleaner for hazardous locations is equipped with
conductive wheels, which allow for the vacuum cleaner to be
grounded with the floor. Do not substitute the conductive
wheels and use only replacement conductive wheels supplied
by the manufacturer.
U
WARNING:
U
Improper connection of the equipment-grounding conductor
can result in a risk of electric shock. Check with a qualified
electrician or service person if you are in doubt as to whether
an outlet is properly grounded. If the plug will not fit the outlet,
have a proper plug or outlet installed by a qualified electrician.
No adaptor should be used with this vacuum cleaner
U

To effectively dissipate static electricity and to ensure spark-
free operation, this vacuum cleaner must be grounded during
use.

Do not operate vacuum cleaner if the electrical outlet is not
properly grounded or if the grounding is questionable.
