Electromagnetic Compatibility - Smarter tools S-200i Manual De Instrucciones

Each unit incorporates an INRUSH circuit. When the MAIN CIRCUIT SWITCH is
turned on, the inrush circuit provides pre-charging for the input capacitors. A
relay in the Power Control Assembly (PCA) will turn on after the input capacitors
have charged to operating voltage (after approximately 5 seconds)
Damage to the PCA could occur if 133 VAC or higher is applied to the Primary
Power Cable.

3.4 Electromagnetic Compatibility

Extra precautions for Electromagnetic Compatibility may be required when this
Welding Power Source is used in a domestic situation.
A. Installation and Use - Users Responsibility
The user is responsible for installing and using the welding equipment according
to the manufacturer's instructions. If electromagnetic disturbances are detected
then it shall be the responsibility of the user of the welding equipment to resolve
the situation with the technical assistance of the manufacturer. In some cases
this remedial action may be as simple as earthing the welding circuit, see NOTE
below. In other cases it could involve constructing an electromagnetic screen
enclosing the Welding Power Source and the work, complete with associated
input filters. In all cases, electromagnetic disturbances shall be reduced to the
point where they are no longer Trouble-some.
B. Assessment of Area
Before installing welding equipment, the user shall make an assessment of
potential electromagnetic problems in the surrounding area. The following shall
be taken into account.
1. Other supply cables, control cables, signaling and telephone cables; above,
below and adjacent to the welding equipment.
