Connection & Installation
3.1 Installation Precautions
Attention must be paid when installing the welding unit; the surface should be horizontal, vibration-free and
non-slip surface. The load-carrying capacity of the floor space should be at least double the weight of the unit.
When working in high-lying locations, such as bridges, ladders or platforms, the Nelweld N550c Arc Charger
must be secured against the risk of falling.
The Arc Charger must be adequately protected against the intrusion of liquids. It may not be installed on liquid-
bearing pipelines.
In order to guarantee unimpeded temperature exchange with the environment, a minimum clearance of 39.4
″
(1 m) to existing heat sources must be observed.
Attention must be paid to the fact that the ventilation slits on the unit casing are kept free.
