Independent approval by BGIA has been given.

Environmental limits

Instructions in this User Guide regarding transport, storage, installation and use of the
drive must be complied with, including the specified environmental limits. Drives must
not be subjected to excessive physical force.

Compliance with regulations

The installer is responsible for complying with all relevant regulations, such as national
wiring regulations, accident prevention regulations and electromagnetic compatibility
(EMC) regulations. Particular attention must be given to the cross-sectional areas of
conductors, the selection of fuses or other protection, and protective earth (ground)
connections.
This User Guide contains instruction for achieving compliance with specific EMC
standards.
Within the European Union, all machinery in which this product is used must comply
with the following directives:
98/37/EC: Safety of machinery.
89/336/EEC: Electromagnetic Compatibility.
Motor
Ensure the motor is installed in accordance with the manufacturer's recommendations.
Ensure the motor shaft is not exposed.
Standard squirrel cage induction motors are designed for single speed operation. If it is
intended to use the capability of the drive to run a motor at speeds above its designed
maximum, it is strongly recommended that the manufacturer is consulted first.
Low speeds may cause the motor to overheat because the cooling fan becomes less
effective. The motor should be fitted with a protection thermistor. If necessary, an
electric forced vent fan should be used.
The values of the motor parameters set in the drive affect the protection of the motor.
The default values in the drive should not be relied upon.
It is essential that the correct value is entered in parameter 0.46 motor rated current.
This affects the thermal protection of the motor.

Adjusting parameters

Some parameters have a profound effect on the operation of the drive. They must not
be altered without careful consideration of the impact on the controlled system.
Measures must be taken to prevent unwanted changes due to error or tampering.
