Input power to the machine must be grounded. For wye power, the neutral must be grounded. For delta power, a
central leg ground or one leg ground should be used. The machine will not function properly on ungrounded power.
(This is not a factor with the External 480V Option.)
The rated horsepower of the machine may not be achieved if the imbalance of the incoming voltage is beyond an
acceptable limit. The machine may function properly, yet may not deliver the advertised power. This is noticed more
often when using phase converters. A phase converter should only be used if all other methods cannot be used.
The maximum leg-to-leg or leg-to-ground voltage should not exceed 260 volts, or 504 volts for high-voltage ma-
chines with the Internal High Voltage Option.

The current requirements shown in the table reflect the circuit breaker size internal to the machine. This breaker
has an extremely slow trip time. It may be necessary to size the external service breaker up by 20-25%, as
indicated by “power supply”, for proper operation.
2 The high-voltage requirements shown reflect the Internal 400V configuration which is standard on European
machines. Domestic and all other users must use the External 480V option.

EQUIREMENTS
The mill requires a minimum of 100 psi at the input to the pressure regulator on the back of the machine. A volume
of 4 scfm (9scfm for EC and HS mills) is also necessary. This should be supplied by at least a two-horsepower
compressor, with a minimum 20-gallon tank, that turns on when the pressure drops to 100 psi.
NOTE: Add 2 scfm to the minimum air requirements (below) if the operator will be
using the air nozzle during pneumatic operations.
Machine Type Main Air Regulator Input Airline Hose Size
EC-300 85 psi 1/2” I.D.
EC-400 85psi 1/2” I.D.
EC-1600 85psi 1/2” I.D.
HS 3/4/6/7 incl R models 85psi. 1/2” I.D.
VF-1 - VF-11 (40Taper), VM 85psi 3/8” I.D.
VF-5 - VF-11 (50 Taper) 85psi 1/2” I.D.
VR Series 85psi 1/2” I.D.
VS 1/3 85psi 1/2” I.D.
The recommended method of attaching the air hose is to the barb fitting at the back of the machine with a hose
clamp. If a quick coupler is desired, use a 1/2" coupler.
NOTE: Excessive oil and water in the air supply will cause the machine to malfunction.
The air filter/regulator has an automatic bowl dump that should be empty
before starting the machine. This must be checked for proper operation
monthly. Also, excessive contaminants in the air line may clog the dump valve
and cause oil and/or water to pass into the machine.
NOTE: Auxiliary air connections should be made on the unregulated side of the air
filter/regulator.
WARNING! WARNING! WARNING! WARNING! WARNING!
When the machine is operating and the pressure gauge (on the ma-
chine regulator) drops by more than 10 psi during tool changes or
pallet changes, insufficient air is being supplied to the machine.
