ACS 300 User’s Manual vii
Safety Instructions
WARNING! The ACS 300 motor cable terminals are at a
dangerously high voltage when power is applied regardless
of motor operation.
There can be dangerous voltages inside the ACS 300 from
external control circuits when the ACS 300 AC line power is
shut off. Exercise appropriate care when working with the
unit. Negligence to these instructions can cause physical
injury and death.
WARNING! The ACS 300 may introduce electric motors,
drive train mechanisms and driven machines to an extended
operating range. It should be confirmed that all equipment is
suitable for these conditions.
Do not make any voltage tolerance tests (Hi Pot or Meggar)
on any part of the ACS 300. Disconnect motor wires from
the ACS 300 before making any such tests on the motor or
motor wiring.
Failure to follow these instructions can result in permanent
damage to the ACS 300.
WARNING! Certain parameter settings and external control
signals may cause the ACS 300 to start up automatically
after an input power failure.
The motor rotational direction can be locked to forward only
by using the DIR parameter. See page 64 for more details.
Mechanical faults on the motor, power failure or other faults
may cause stoppages. Correcting the fault may cause the
motor to restart. Take all necessary precautions to ensure
personnel safety and to avoid damage to equipment and
property before motor restart.
