Grounding Instructions - Ingersoll Rand ESCB20 Manual De Instrucciones

The Controller should be grounded while in use to protect the operator from electric shock. The controller is equipped with a
three–conductor cord and three–prong grounding–type plug to fit the proper grounding–type receptacle.
The green (or green and yellow) conductor in the cord is the grounding wire. Never connect the green (or green and
yellow)wire to a live terminal. If your unit is for use on less than 150V, it has a plug that looks like that shown in Figure A.
An adapter (see Figure B) is available for connecting Figure A–type plugs to 2–prong receptacles. The green colored rigid
grounding strap extending from the adapter must be connected to a permanent ground such as to a properly grounded outlet
box.

connections.

Use only 3–wire extension cords that have 3–prong grounding–type plugs and 3 pole receptacles that accept the
controller's plug. Replace or repair damaged cords.
