Operating Location
The operating location of the Nelweld N550c Arc Charger should be limited to restricted areas of industry and
manufacturing.
Welding can cause radio interference in residential and commercial areas
.
Welds that are performed at low temperature may have a negative influence upon the welding result.
To protect people not involved, the operating location must be amply cordoned off and clearly marked with
warning and informatory signs.
Inflammable and explosive materials must be removed from the danger zone.
We expressly point out that welding in commercial areas, in the open or in
open halls is as a general principle forbidden.
The power unit will operate in harsh environments. Regardless, it is important to follow simple preventative
measures in order to assure long life and reliable operation.
The machine must be located where there is free circulation of clean air such that air movement in the
back, out the sides and bottom will not be restricted.
Dirt and dust that can be drawn into the machine should be kept to a minimum. Failure to observe these
precautions can result in excessive operating temperatures and nuisance shutdown.
Keep the machine dry. Shelter it from rain and sun. Do not place on wet ground or in puddles.
DO NOT MOUNT OVER COMBUSTIBLE SURFACES. Where there is a combustible
surface directly under stationary or fixed electrical equipment, the surface should
be covered with a steel plate of at least .063″ (1.6 mm) thick, which should extend
not less than 5.9″ (150 mm) beyond the equipment on all sides.
Incorrect connection may result in equipment damage.
