1-5 ELECTRICAL CONNECTIONS:
INSTALLATION & SETUP
NOTE: All electrical connections should be made by a qualified electrician.
Before making any electrical connections, insure that the voltage listed on the electrical box and circuit
breakers matches that of your facility (i.e. 230V - 3 Phase -40 Amp).
Refer to Figure 1-3 for the standard electrical connections. Norfield recommends that you have a main
disconnect switch for the input source near the machine. This switch is usually wall mounted near the
machine in a position convenient to the operator (or maintenance person) for safety reasons.
After power has been connected, check the rotation of the Lock Drill Motor. Correct rotation has the mo
-
tor turning COUNTER-CLOCKWISE when viewed from the front of the machine. If the rotation is not
correct, have the electrician reverse the two outside leads on the three phase input.

1-4 AIR SUPPLY AND CONNECTIONS:
The Magnum requires 2.2 CFM of clean, dry air @ 90 PSI (8.5 CFM if air screwdriver and pre-drill is used)
for proper operation. The air supply is connected to the machine at the filter-regulator-lubricator (FRL)
unit located on the outfeed end of the main frame (FIG 1-2). The supply line should be 1/2” minimum if
the length of the run is 75’ or less. For runs between 100’ and 300’, a 3/4” supply line is recommended.
For convenience, a quick disconnect at the connection point and an air shut-off valve near the machine is
