GROUNDING OF ELECTRICAL
EQUIPPMENT - BATTERY CHARGER
WARNING:
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 the
outlet is properly grounded. Do not modify the plug
provided with the charger. If outlet is not suitable for
safe use; have a properly grounded outlet installed by
a qualified 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 charger shall be grounded while in use to protect
the operator from electric shock. The charger is pro-
vided 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 in-
stalled 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 attach-
ment 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 avail-
able, an adapter may be installed as shown in Figure B
if the outlet box that houses the receptacle is ground-
ed. 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 attach-
ment 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 adaptors to
other plug types must be done in accordance with local
regulations.
