GROUNDING INSTRUCTIONS
This product must be grounded. If it should malfunction or breakdown,
grounding provides a path of least resistance for electric current to reduce
the risk of electric shock.
DANGER: IMPROPER CONNECTION OF THE EQUIPMENT -
GROUNDING CONDUCTOR CAN RESULT IN A RISK OF
ELECTROCUTION. CHECK WITH A QUALIFIED ELECTRICIAN
OR SERVICE PERSON IF YOU ARE IN DOUBT AS TO WHETHER
THE UNIT IS PROPERLY GROUNDED.
The screw and ground terminal on the frame must always be used to con-
nect the unit to a suitable ground source. The ground path should be made
with #8 size wire. Connect the terminal of the ground wire between the star
washers and screw then tighten the screw fully. Connect the other end of the
wire securely to a suitable ground source.
The National Electric Code contains several practical ways in which to estab-
lish a good ground source. Examples given below illustrate a few of the ways
in which a good ground source may be established.
A metal underground water pipe in direct contact with the earth for at least
10 feet can be used as a grounding source. If a pipe is unavailable, an 8 foot
length of pipe or rod may be used as the ground source. The pipe should
be 3/4 inch trade size or larger and the outer surface must be noncorrosive.
If a steel or iron rod is used it should be at least 5/8 inch diameter and if a
nonferrous rod is used it should be at least 1/2 inch diameter and be listed
as material for grounding. Drive the rod or pipe to a depth of 8 feet. If a
rock bottom is encountered less than 4 feet down, bury the rod or pipe in a
trench. All electrical tools and appliances operated from this unit, must be
properly grounded by use of a third wire or be "Double Insulated".
It is recommended to:
1. Use electrical devices with 3 prong power cords.
2. Use an extension cord with a 3 hole receptacle and a 3 prong plug at the
opposite ends to ensure continuity of the ground protection from the unit
to appliance.
Mi-T-M strongly recommend that all applicable federal, state and local regu-
lations relating to grounding specifications be checked and followed.
LINE TRANSFER SWITCH:
If this unit is used for standby service, it must have a transfer switch between
the utility power service and the unit. The transfer switch not only prevents
the utility power from feeding into the unit, but also prevents the unit from
feeding out into the utility company's lines. This is intended to protect the
serviceman who may be working on a damaged line.
THIS INSTALLATION MUST BE DONE BY A LICENSED ELECTRICIAN
AND ALL LOCAL CODES MUST BE FOLLOWED.
