Before energising the equipment, the following should be checked:
Voltage rating and polarity;
Protective fuse rating;
Integrity of earth connection
Equipment operating conditions
The equipment should be operated within the specified electrical and
environmental limits.
Insulation and dielectric strength testing
Insulation testing may leave capacitors charged up to a hazardous voltage.
At the end of each part of the test, the voltage should be gradually reduced to
zero, to discharge capacitors, before the test leads are disconnected.
Disposal
It is recommended that incineration and disposal to water courses is avoided.
The product should be disposed of in a safe manner.
Technical Specifications
