Emission Compliance

This equipment has been tested and found to comply with the limits applied by the

local regulations.

These limits are designed to provide reasonable protection against harmful interference

in a residential installation. This equipment generates, uses and can radiate radio

frequency energy and, if not installed and used in accordance with the instructions,

may cause harmful interference to radio communications. However, there is no

guarantee that interference will not occur in a particular installation. If this equipment

does cause harmful interference to radio or television reception, which can be

determined by turning the equipment off and on, you are encouraged to try to correct

the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and the receiver.

Disclaimers 1

Three Phase System MAN-01-00507-4.2

Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.

Consult the dealer or an experienced radio/TV technician for help.

Changes or modifications not expressly approved by the party responsible for

compliance may void the user’s authority to operate the equipment.
