EMC:
This equipment is Class A according to the EMC standard EN55011 and is
intended for use in a non-domestic environment only. Interference from
nearby sources of RFI (radio frequency interference) may affect the output signals. Likewise, this
equipment may affect other equipment: PCs, laptops, tablets and mobile phones may be affected.
Warnings:
For your safety, this product should be used in accordance with these instructions, otherwise the protection
provided may be impaired.
Do not open or remove covers or panels. Repairs and service may only be carried out by our repair agent,
otherwise the warranty may be void.
Use only the 3-core mains cable supplied with the unit. If the mains cable is replaced, the rating of the
replacement must be the same or better than the original.
The unit must be earthed at all times. The unit is earthed/grounded through the 3-core mains lead, so no
additional earth connection is required.
Always position the generator so that it can be disconnected from the mains, if an emergency arises.
This unit is intended for use in DRY conditions. Avoid spillage of water and other liquids on to the unit. If
spillage occurs, disconnect the mains supply. version G85793 2017
