Safety Notice
:
This equipment contains voltages that may be as great as 1000 volts! Electrical shock
can cause serious or fatal injury. Only qualified personnel should attempt the start–up
procedure or troubleshoot this equipment.
This equipment may be connected to other machines that have rotating parts or parts
that are driven by this equipment. Improper use can cause serious or fatal injury. Only
qualified personnel should attempt the start–up procedure or troubleshoot this equipment.
PRECAUTIONS:
WARNING: Do not touch any circuit board, power device or electrical
connection before you first ensure that power has been
disconnected and there is no high voltage present from this
equipment or other equipment to which it is connected. Electrical
shock can cause serious or fatal injury. Only qualified personnel
should attempt the start–up procedure or troubleshoot this
equipment.
WARNING: Be sure that you are completely familiar with the safe operation of
this equipment. This equipment may be connected to other
machines that have rotating parts or parts that are controlled by
this equipment. Improper use can cause serious or fatal injury.
Only qualified personnel should attempt the start–up procedure or
troubleshoot this equipment.
WARNING: Do not use motor overload relays with an automatic reset feature.
These are dangerous since the process may injure someone if a
sudden or unexpected automatic restart occurs. If manual reset
relays are not available, disable the automatic restart feature using
external control wiring.
WARNING: This unit has an automatic restart feature that will start the motor
whenever input power is applied and a RUN (FWD or REV)
command is issued and maintained. If an automatic restart of the
motor could cause injury to personnel, the automatic restart feature
should be disabled by changing the “Restart Auto/Man” parameter
to MANUAL.
WARNING: Be sure the system is properly grounded before applying power.
Do not apply AC power before you ensure that grounds are
connected. Electrical shock can cause serious or fatal injury.
WARNING: Do not remove cover for at least five (5) minutes after AC power is
disconnected to allow capacitors to discharge. Electrical shock can
cause serious or fatal injury.
WARNING: Improper operation of control may cause violent motion of the
motor shaft and driven equipment. Be certain that unexpected
motor shaft movement will not cause injury to personnel or damage
to equipment. Peak torque of several times the rated motor torque
can occur during control failure.
WARNING: Motor circuit may have high voltage present whenever AC power is
applied, even when motor is not rotating. Electrical shock can
cause serious or fatal injury.
