Tormach 1100M - 3.2 Electrical and Power Requirements

3: SITE REQUIREMENTS
Figure 3-3: Example of the typical operator workstation.
For information on the machine controls, go to "System
Basics" (page111).
3.2 ELECTRICAL AND POWER REQUIREMENTS
You must verify that the site conforms to the following
electrical and power requirements. If it doesn't, you may
consider other options: go to "Options for Non-Conforming
Sites" (below).
3.2.1 Electrical Requirements
A certified electrician must make all electrical connections,
and it's your responsibility to verify that the electrical
installation of the machine meets all local regulations and
electrical codes.
l
Primary Power RequiredSingle-Phase 230 Vac, 50/60
Hz
Maximum 240 Vac, 50/60 Hz
l
Recommended Circuit AmperageDedicated 20 A
breaker
Maximum 60 A breaker
3.2.2 Power Requirements
If the site conforms to the electrical requirements, verify that
it meets the following power requirements:
l
No Electrical Noise Primary power must be provided
by a dedicated circuit, which must be isolated from
electrically-noisy devices like welders or plasma torches.
The machine should be isolated from inductive loads
from items like vacuum cleaners or air compressors.
l
No Ground Fault Circuit Interrupter Power for the
machine must not be protected by a ground fault circuit
interrupter (GFCI), as it interferes with the operation of
the variable frequency drive (VFD) spindle controller.
l
Proper Grounding You must properly ground the
power input to the machine. Examine the continuity
between bare metal on the machine frame and true
earth ground (a water pipe or similar) to verify that it's
properly grounded.
l
Correct Plug Pattern The machine is shipped with a
NEMA 6-20P plug, designed for use with a NEMA6-20R
receptacle.
3.2.3 Options for Non-Conforming Sites
For sites that don't conform to the specified "Electrical and
Power Requirements" (above), you may consider the following.
You must consult with an electrician to determine the
suitability for your site.
l
Buck-Boost Transformer Used to adjust line voltages.
While the machine can run on line voltages between 200
to 240 Vac, spindle performance is reduced on line
voltages below 230 Vac, and damage to electrical
components is possible on line voltages above 240 Vac.
To prevent reduction in spindle performance or damage
to electrical components, we recommend the Buck-
Boost Transformer (PN32554).
