2.5
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 instructions for achieving compliance with specific
EMC standards.
2.6 Risk
analysis
In any application where a malfunction of the Drive could lead to damage,
loss or injury, a risk analysis must be carried out, and where necessary,
further measures taken to reduce the risk. This would normally be an
appropriate form of independent safety back-up system using simple
electro-mechanical components.
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 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 over-heat because the cooling fan
becomes less effective. The motor should then be fitted with a protection
thermistor. If necessary, a separate cooling fan should be used.
