1.8
Access to equipment
Access must be restricted to authorized personnel only. Safety regulations which apply
at the place of use must be complied with.
1.9
Environmental limits
Instructions in this guide regarding transport, storage, installation and use of the
equipment must be complied with, including the specified environmental limits.
This includes temperature, humidity, contamination, shock and vibration. Drives must
not be subjected to excessive physical force.
1.10
Hazardous environments
The equipment must not be installed in a hazardous environment (i.e. a potentially
explosive environment).
1.11
Motor
The safety of the motor under variable speed conditions must be ensured.
To avoid the risk of physical injury, do not exceed the maximum specified speed of the
motor.
Low speeds may cause the motor to overheat because the cooling fan becomes less
effective, causing a fire hazard. The motor should be installed 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 must not be relied upon. It is essential that the correct
value is entered in the Motor Rated Current parameter.
1.12
Mechanical brake control
Any brake control functions are provided to allow well co-ordinated operation of an
external brake with the drive. While both hardware and software are designed to high
standards of quality and robustness, they are not intended for use as safety functions,
i.e. where a fault or failure would result in a risk of injury. In any application where the
incorrect operation of the brake release mechanism could result in injury, independent
protection devices of proven integrity must also be incorporated.
1.13
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.
1.14
Electromagnetic compatibility (EMC)
Installation instructions for a range of EMC environments are provided in the relevant
Power Installation Guide. If the installation is poorly designed or other equipment does
not comply with suitable standards for EMC, the product might cause or suffer from
disturbance due to electromagnetic interaction with other equipment. It is the
responsibility of the installer to ensure that the equipment or system into which the
product is incorporated complies with the relevant EMC legislation in the place of use.
