MACHINE ELECTRICAL CONNECTION
1. A qualified electrician should do the electrical hookup to
your new machine. The power source supplied must be the
same as specified on the Serial Plate, which is attached to
the motor flange (Figure 13).
2. Connections are made at the fuse block located inside the
electrical box mounted on the side of the machine. Refer to
the diagram for a three-phase hookup (Figure 14) and a
single-phase manual mach. hookup (Figure 15). Please
note that single-phase non-manual machines require a 4-
wire hookup; which includes 2 wires to hot, 1 wire to ground
and 1 wire to neutral. These machines will not operate
without the neutral connection.
On
Single Phase Non-Manual Machines
the common wire must be
connected to the bottom right of the main terminal block.
3. After the electrical hookup is completed, verify correct rotation of the
table and grinding motor.
4. Turn on table motor. Table should rotate in counter clockwise direction when viewed from the top
(see arrow label on edge of table). Turn on grinding motor. Motor should rotate in clockwise direction
when viewed from the top (see arrow label on front of motor)
5. If both the table motor and the grinding motor are rotating the wrong direction, interchange any two
of the three HOT LEADS of the 3 Phase connections at the electrical box (Figure 14). DO NOT
INTERCHANGE THE GROUND WIRE. If the rotation is correct on one motor, but not the other,
contact Van Norman technical assistance.
6. On 1 Phase (Single Phase) machines, if rotation is not correct, contact Irontite Support for
assistance.
