General Safety Precautions
Read and follow these safety precautions before you operate the
equipment or perform maintenance.
Obey all cautions or warnings given in all applicable procedures.
Never bypass or override machine safety devices.
Always use sufficient personnel and/or lifting equipment to move the
actuator.
Do not contact the actuator drive shaft, either directly or indirectly, unless
the system is de-energized, as injury may occur.
This equipment contains high voltage and rotating parts (fans). Ignoring the
safety and warning information may result in death, severe personal injury,
or damage to property.
Do not conduct maintenance procedures unless the equipment is
de-energized.
Do not begin work on the power stage and the connections until you have
made sure that the system has been de-energized.
Observe all applicable regulations and verify the proper operation of all
safety devices when performing installation, repair, or maintenance
procedures.
Due to technical requirements, devices or motors may include individual
components that contain dangerous materials.
Do not replace or substitute Woodward products and components with
non-Woodward devices without authorization from Woodward.
Observe all applicable regulations during installation.
PE (protective earth [ground]) connections as shown in this document are
required to avoid personal injuries caused by high voltages.
This driver may not be compatible with earth leakage circuit breakers
(E.L.C.B.s, sometimes called ground fault breakers) due to high current
leakage to ground in the converter and the motor.
During operation, the power converter and motor work can lead to leakage
currents to earth that are dissipated via the specified protective earths and
may result in a current-operated E.L.C.B. on the input side blowing
prematurely.
To operate the driver in an IT ground network environment, the IT EMI Filter
type must be installed.
Make sure the plastic covers over the power supply connections are in place
before applying power.
Before switching on the driver, you must carefully check the functions of all
higher safety equipment to prevent injury to people.
Some movement of the actuator drive shaft is possible during the initial
application of power. Proper precautions should be taken to avoid personal
injury or damage to property.
