If repair or replacement of the electric cord or
plug is necessary, do not connect the
equipment-grounding conductor to a live
terminal.
Grounded, cord-connected tools intended
for use on a supply circuit having a nominal
rating less than 150 volts:
This mortiser has been pre-wired for 115 volt for
use on a circuit that has an outlet that looks like
the one illustrated in Figure 12. The tool has a
grounding plug similar to the plug illustrated in
Figure 12.
A temporary adapter, (Figure 13) may be used
to connect this plug to a 2-pole receptacle 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.
Grounded, cord-connected tools intended
for use on a supply circuit having a nominal
rating between 150 to 230 volts, inclusive:
If the Mortiser is to be re-wired for 230 volt
operation, it will use an outlet that looks similar
to the one in Figure 14. An appropriate 230 volt
grounding plug must be installed on the power
cord. This plug will look similar to that illustrated
in Figure 14.
Make sure outlet and plug have the same
configuration. No adapter is available or should
be used with 230 volt operation.
If the machine is to be re-wired for 230 volt
operation, consult the diagram inside the switch
box. The re-wiring should be made by qualified
service personnel, and after re-connection the
tool should comply with all local codes and
ordinances.
Check with a qualified electrician or service
personnel if the grounding instructions are not
completely understood, or if in doubt as to
whether the tool is properly grounded.
Extension Cords
If an extension cord is necessary, make sure the
cord rating is suitable for the amperage listed on
the machine's motor plate. An undersize cord
will cause a drop in line voltage resulting in loss
of power and overheating.
The chart in Figure 15 shows the correct size
cord to use based on cord length and the amp
rating on your machine’s motor plate. If in doubt,
use the next heavier gauge. The smaller the
gauge number, the heavier the cord.
