GROUNDING OF ELECTRICAL
EQUIPMENT
WARNING: Improper connection of the
equipment–grounding conductor can result in a risk
of electric shock. Check with a qualied electrician or
service person if you are in doubt as to whether the
outlet is properly grounded. Do not modify the plug
provided with the equipment If outlet is not suitable for
safe use; have a properly grounded outlet installed by
a qualied electrician.
North America: Always use a properly grounded 3-wire
extension cord, which has male and female plugs. If
25 foot [7.6m] extension cords are used, the electrical
carrying capacity should be no less than 14-3 ST, 50
foot [15.2m] extension cords no less than 12-3 ST.
Grounding Instructions
This equipment shall be grounded while in use to
protect the operator from electric shock. The charger
is provided with a three-conductor cord and a three-
contact grounding type attachment plug. The plug
must be plugged into an appropriate outlet that is
properly installed and grounded in accordance with all
local codes and ordinances. The green conductor in
the cord is the ground wire. Never connect this wire to
other than the grounding pin of the attachment plug.
If the cord provided with the charger has an attachment
plug as shown in Figure A. below, it is intended for use
on a nominal, 120-volt circuit. If a properly grounded
receptacle as shown in Figure A is not available, an
adapter may be installed as shown in Figure B if the
outlet box that houses the receptacle is grounded. Be
sure to fasten the grounding tab (the green colored
rigid ear, lug or the like extending from the adapter)
with a metal faceplate screw.
If the cord provided with the charger has an attachment
plug as shown in Figure C, it is intended for use on a
nominal 240-volt circuit (single phase only). Changes
to the attachment plug or use of adapters to other
plug types must be done in accordance with local
regulations.
NOTE: In Canada, the use of a temporary adapter is not
permitted by Canadian electrical code, C22.1.
