to the ON position.
6. Observe the direction of rotation of the
coolant pump. You can see the pump shaft rotate
on top of the pump at the rear of the drill press.
There will be an arrow cast into the pump, and the
shaft should be rotating in the direction of the arrow.
If the shaft is rotating in the wrong direction, the
power is connected, backwards. Correct as follows:
7. Disconnect power to the machine by turning it off
at the cutout box.
8. Reverse
any two of the power lead connections.
9. Repeat steps 4, 5, and 6, above, and you should
observe the pump shaft turning in the correct direc-
tion. The electrical service to the machine is now
complete.
Caution
Electrical set-up should be performed only by
a licensed electrician who is familiar with national
and local electrical codes.
The Model 1230 is shipped after testing all
functions and circuits under electrical power
specified for the machine and motors. The only
hook-up requirement should be for correct connec-
tion to an appropriate cutout on an appropriate
service branch.
Where the following instructions do not agree
with local electrical codes and procedures, the
applicable codes and procedures should be
followed, exclusively.
Wiring diagram
A wiring diagram for the drill press is found on
the facing page. This diagram is for reference by
your licensed installing or servicing electrician. In
addition to using a licensed electrician for connection
to the drill press service branch, the servicing of
components and circuits inside the control box should
be serviced only by a qualified electrician. This
includes fuse replacement, if required. If any of
these fuses, upon replacement, should continue to
fail at short service intervals, the electrician should be
asked to check all machine components for excessive
loads, short circuits or other failures.
Electrical
Electrical branch service
The machine is wired for either a 230 or 460 3-
phase service branch. The cable supplying the drill
press will be tagged with the voltage at which the
machine was tested and corresponding to the
customer's order.
If the tag has been lost, it will be necessary for
you to open the electrical cabinet on the rear of the
drill press and examine the connections on the
transformer found inside the box. The transformer
can be connected to either a 230 or 460 volt source
and its taps are labeled for voltage. By locating the
source tap on the transformer you will be able to
determine the branch voltage required.
A service disconnect is recommended. The
use of fuses or circuit breakers for each of the
voltage supply wires is required. Use fuses or circuit
breakers which are appropriate to the voltage for the
motor system delivered.
A positive cut-out/lock-out lever or rocker switch
should be located on the outside of the service
disconnect to allow the machine operator to discon-
nect the machine from the branch circuit when
working with tooling on the machine.
To connect the branch to the drill press
1. Disconnect the service branch to the machine by
moving the lever or rocker switch on the cutout box to
OFF.
2 Connect the green wire (or green with white trace)
to the branch ground.
3. Connect the remaining three wires in the cable
(labeled R,S and T) to the three power lines in the
branch.
4. Turn the power to the machine ON at the cutout
box.
5. Turn the coolant pump power switch (See Fig. 1)
