2.5 Access
Access must be restricted to authorized personnel only. Safety regulations which apply
at the place of use must be complied with.
The IP (Ingress Protection) rating of the drive is installation dependant.
2.6 Compliance and 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 and other protection, and protective ground (earth)
connections.
The IM-pAC Technical Data Guide contains instructions 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
2.7 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 a 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 installed with a protection thermistor. If necessary, an
electric force 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 into parameter 06, motor rated current.
This affects the thermal protection of the motor.
2.8 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.
2.9 Electrical installation
2.9.1 Electric shock risk
The voltages present in the following locations can cause severe electric shock and may
be lethal:
•
AC supply cables and connections
• DC bus, dynamic brake cables and connections
• Output cables and connections
• Many internal parts of the drive, and external option units
Unless otherwise indicated, control terminals are single insulated and must not be
touched.
