Electrical Installation
IMPORTANT: Electrical ratings are subject to
change. Refer to serial decal for electrical ratings
information specific to your machine.

warranty does not cover compounds that fail as a
result of improper input voltage.
The AC inverter drive requires a clean power supply
free from voltage spikes and surges. A voltage monitor
should be used to check incoming power. The
customer’s local power company may provide such a
monitor.
If input voltage measures above 240V for a 220V
drive or above 415V for a 400V drive, ask the power
company to lower the voltage. As an alternative, a
step-down transformer kit is available from the
distributor.
The AC drive provides overload protection for the
drive motor. However, a separate single or three phase
circuit breaker must be installed for complete
electrical overload protection. This prevents damage
to the motor by disconnecting all legs if one should be
lost accidentally. Check the data plate on the back of
the machine or consult Table 12 for circuit breaker
requirements.
IMPORTANT: Do NOT use fuses in place of a
circuit breaker.
The machine should be connected to an individual
branch circuit not shared with lighting or other
equipment.
The connection should be shielded in a liquid tight or
approved flexible conduit with proper conductors of
correct size installed in accordance with the National
Electric Code or other applicable codes. The
connection must be made by a qualified electrician
using the wiring diagram provided with the machine,
or according to accepted European standards for CE-
approved equipment.
Use wire sizes indicated in Table 12 for runs up to
50 feet.
Use next larger size for runs of 50 to 100 feet. Use two
sizes larger for runs greater than 100 feet.
For personal safety and proper operation, the machine
must be grounded in accordance with state and local
codes. If such codes are not available, grounding must
conform with the National Electric Code, article 250
(current edition). The ground connection must be
made to a proven earth ground, not to conduit or water
pipes.
Before starting wiring or inspection,
power must be switched OFF. Check to
make sure that the operation panel
indicator is OFF. Any person who is
involved in wiring or inspection shall wait
for at least 10 minutes after the power
supply has been switched OFF and check
that there are no residual voltage using a
tester or the like. The capacitor of the
inverter or the EMC filter is charged with
high voltage for some time after power is
OFF and it is dangerous.

WARNING
Hazardous Voltage. Can cause shock,
burn or death. Verify that a ground wire
from a proven earth ground is connected
to the lug near the input power block on
this machine.
