3.3 This NAPA Digital Wheel Charger is for use on a nominal 120-volt circuit and has a grounding
plug that looks like the plug illustrated below (A). A temporary adapter, which looks like the adapt-
er illustrated in (B) and (C), may be used to connect this plug to a two-pole receptacle as shown in
(B), if a properly grounded outlet is not available. The temporary adapter should be used only until
properly grounded outlet can be installed by a qualified electrician.
DANGER: BEFORE USING ADAPTER AS ILLUSTRATED, BE CERTAIN THAT CENTER
SCREW OF OUTLET PLATE IS GROUNDED. The green-colored rigid ear or lug extending from
adapter must be connected to a properly grounded outlet: make certain it is grounded. If neces-
sary, replace original outlet cover plate screw with a longer screw that will secure adapter ear or
lug to cover plate and make ground connection to grounded outlet.
USE OF AN ADAPTER IS NOT ALLOWED IN CANADA. IF A GROUNDING-TYPE RECEPTACLE
IS NOT AVAILABLE, DO NOT USE THIS CHARGER UNTIL THE PROPER OUTLET IS INSTALLED
BY A qUALIFIED ELECTRICIAN.
