Vision Fitness E3600HRC Owner's Manual page 29

This product is for use on a nominal 120-volt circuit, and has a
grounding plug that looks like the plug illustrated below. A
temporary adapter such as the one illustrated below may be used
to connect this plug to a 2-pole receptacle as shown, 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, or the like
extending from the adapter must be connected to a permanent
ground such as a properly grounded outlet box cover. Whenever
the adapter is used, it must be held in place by a metal screw.
