WARNING
Danger: Indicates a potentially hazardous situation other than electrical, which if not avoided, could
result in damage to property.
Within the European Union, all machinery in which this product is used must comply with the Machinery
Directive 2006/42/EC, Safety of Machinery. In particular, the machine manufacturer is responsible for
ensuring that the electrical equipment complies with EN60204-1 and providing a disconnecting device which
must be one of the following types:
• A switch-disconnector, utilization category AC-23B (EN 60947-3).
• A circuit breaker suitable for isolation in accordance with EN 60947-2.
• A disconnector with an integrated auxiliary contact that ensures under all circumstances the switching
devices break the load circuit prior to opening of the main contacts of the disconnector (EN 60947-3).
For installation in other regions, conformance with local electrical regulations and codes of practice must be
adhered to.
The level of integrity offered by the PACMotion VFD control input functions – for example stop/start,
forward/reverse and maximum speed, is not sufcient for use in safety-critical applications without
independent channels of protection. All applications where malfunction could cause injury or loss of life must
be subject to a risk assessment and further protection provided where needed.
The driven motor can start at power up if the enable input signal is present.
The STOP function does not remove potentially lethal high voltages. ISOLATE the drive and wait 10 minutes
before starting any work on it. Never carry out any work on the Drive, Motor or Motor cable whilst the input
power is still applied.
The PACMotion VFD can be programmed to operate the driven motor at speeds above or below the
speed achieved when connecting the motor directly to the mains supply. Obtain conrmation from the
manufacturers of the motor and the driven machine about suitability for operation over the intended speed
range prior to machine start up.
Do not activate the automatic fault reset function on any systems whereby this may cause a potentially
dangerous situation.
IP55 and IP66 drives provide their own pollution degree 2 environments. IP20 drives must be installed in a
pollution degree 2 environment, mounted in a cabinet with IP54 or better.
PACMotion VFDs are intended for indoor use only.
When mounting the drive, ensure that sufcient cooling is provided. Do not carry out drilling operations with
the drive in place, dust and swarf from drilling may lead to damage.
The entry of conductive or ammable foreign bodies should be prevented. Flammable material should not be
placed close to the drive.
Relative humidity must be less than 95% (non-condensing).
Ensure that the supply voltage, frequency and no. of phases (1 or 3 phase) correspond to the rating of the
PACMotion VFD as delivered.
Never connect the mains power supply to the Output terminals U, V, W.
Do not install any type of automatic switchgear between the drive and the motor.
Wherever control cabling is close to power cabling, maintain a minimum separation of 100mm and arrange
crossings at 90 degrees.
Ensure that all terminals are tightened to the appropriate torque setting.
Do not attempt to carry out any repair of the PACMotion VFD. In the case of suspected fault or malfunction,
contact your local Emerson Sales Partner for further assistance.
Do not operate the drive with any of the enclosure covers removed.
