Grounding & Plug Requirements; Extension Cords - Promac 941A Operating Instructions Manual

event of certain malfunctions or
breakdowns, grounding reduces the risk of
electric shock by providing a path of least
resistance for electric current. This machine
is equipped with a power cord that has an
equipment-grounding wire and a grounding
plug. The plug must only be inserted into a
matching receptacle (outlet) that is properly
installed and grounded in accordance with
all local codes and ordinances.
Improper connection of the equipment-
grounding wire can result in a risk of
electric shock. The wire with green (or
green-yellow) insulation is the equipment-
grounding wire. If repair or replacement of
the power cord or plug is necessary, do not
connect the equipment-grounding wire to a
live (current carrying) terminal. Check with
a qualified electrician or service personnel
if you do not understand these grounding
requirements, or if you are in doubt about
whether the tool is properly grounded. If
you ever notice that a cord or plug is
damaged or worn, disconnect it from power,
and immediately replace it with a new one.

Extension Cords

We do not recommend using an extension
cord with this machine. If you must use an
extension cord, only use it if absolutely
necessary and only on a temporary basis.
Extension cords cause voltage drop, which
may damage electrical components and
shorten motor life. Voltage drop increases
as the extension cord size gets longer and
the gauge size gets smaller (higher gauge
numbers indicate smaller sizes). Any
extension cord used with this machine must
contain a ground wire, match the required
plug and receptacle, and meet the following
requirements:
Voltage: 230V
Minimum Gauge Size....................2 mm ²
Maximum Length.........................6 m.
