1
After unpacking the converter, it is necessary to check up visually the presence of damages which could arise during
transport.
2
Check up the correspondence between the delivered frequency converter and the order - check up the ratings plate on the
case. Delivery includes:
•
the frequency converter with the User Manual,
•
a choke – if it was ordered, recommended for rated power 5.5 kW and above,
•
a ferrite ring or RFI filter - depending on the order.
3
Check up the correspondence between the conditions in which the converter will be used and conditions of an environment
for which it is designed (section 1.4).
4
Installation of the frequency converter should be made due to the principles of safety and EMC rules, listed in section 2.
5
Perform the configuration of the converter in accordance with the chapters of this manual.
1.4. Environmental conditions
Degree of pollution
The second degree of pollution has been assumed during the design, at which there are normally only non-
conducting pollution. However, there is a probability of temporary conductivity caused by a condensation, when the
converter is disconnected from the voltage source.
In case the environment in which the frequency converter will work contains pollution, which can influence its
safety, it is necessary to apply appropriate counteraction, using, for example, additional cases, air channels, filters etc.

1.5. Recycle
Equipment containing electrical and electronic components can not be removed into municipal
waste containers. Such equipment must be separated from other wastes and attached to electrical and
electronic waste in accordance with applicable local regulations.
This way you help to prevent uncontrolled waste disposal and promote the recycling of materials.
