Grounding Instructions; Extension Cord - Hitachi EC 710S Manual De Instrucciones

GROUNDING INSTRUCTIONS

This compressor should be grounded while in use to protect the
operator from electric shock. The compressor is equipped with a three-
conductor cord and three-prong grounding type plug to fi t 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
150 volts, it has a plug that looks like that shown in sketch (A) in Figure
on the right. An adapter, see sketches (B) and (C), is available for
connecting sketch (A) type plugs to two-prong receptacles. 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.
NOTE: The grounding adaptor, sketch (C), is prohibited in Canada by
Canadian Electrical Code Part 1. Therefore, the instructions for
its use are not applicable in Canada.
We recommend that you never disassemble the compressor or try to do
any rewiring in the electrical system. Any repairs should be performed
only by HITACHI Service Centers. Should you be determined to make a
repair yourself, remember that the green colored wire is the "grounding"
wire. Never connect this green wire to a "live" terminal. If you replace
the plug on the power cord, be sure to connect the green wire only to
the grounding (longest) prong on a 3-prong plug.
If in doubt, call a qualifi ed electrician and have the receptacle checked
for ground.

EXTENSION CORD

Use only three-wire extension cords that have three-prong grounding-type plugs and three-pole receptacles that accept the
compressor's plug. Replace or repair damaged cord.
Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the
current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table
shows the correct size to use depending on cord length and name plate ampere rating. If in doubt, use the next heavier gage. The
smaller the gage number, the heavier the cord.
