A temporary adapter, similar to the one in Figure
13, may be used to connect this plug to a 2-pole
receptacle if a properly grounded outlet is not
available. The temporary adapter should only be
used until a properly grounded outlet can be
installed by a qualified electrician.
This adapter
is not applicable in Canada.
The green-colored rigid ear, lug, and the like,
extending from the adapter must be connected
to a permanent ground such as a properly
grounded outlet box.
230 Volt Operation
If 230V, single phase operation is desired, the
following instructions must be performed:
1. Disconnect the machine from the power
source.
2. The drill press motor has four leads that are
factory connected for 115V operation. For
230V operation, re-connect the leads as
shown in the diagrams on pages 25 and 26.
3. The 115V attachment plug supplied with the
drill press must be replaced with a UL/CSA
listed plug suitable for 230V operation,
similar to the plug illustrated in Figure 14.
Contact your local Authorized Powermatic
Service Center or qualified electrician for
proper procedures to install the plug.
4. The drill press must comply with all local
and national codes after the 230 volt plug is
installed.
5. The drill press with a 230-volt plug should
only be connected to an outlet having the
same configuration as shown in Figure 14.
No adapter is available or should be used
with the 230-volt plug.
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 motor
plate amp rating. If in doubt, use the next
heavier gauge. The smaller the gauge number,
the heavier the cord.
