Noise Emission; Electromagnetic Compatibility (Emc); Technical Data - Würth MM 350 Originalbetriebsanleitung

The noise emission measured in accordance with
EN 60974-1 at regular load and maximum operat-
ing point is less than 70 dB(A).
Electromagnetic compatibility
This appliance conforms to the current EMC
standards.
Please note:
Welding machines consume so much power
■
that they may affect public electricity networks.
For this reason the mains supply is subject to re-
quirements regarding the maximum permissible
network impedance. The maximum permissible
mains impedance (Z
mains grid (mains power supply) is specified
in the technical data. Contact the electricity
network operator if required.
The appliance is designed for welding both
■
in commercial and industrial environments
(CISPR 11 class A). Using the appliance in
another environment (e.g. in a residential area)
may affect electrical equipment in that area.
During start-up, electromagnetic problems may
■
be caused in:
• Power cables, control lines, signal and
telecommunication lines in the vicinity of the
welding / cutting appliance
• TV and radio stations / sets
• Computers and other control equipment
• Security equipment in commercial buildings
(e.g. alarm systems)
• Cardiac pacemakers and hearing aids
• Calibrating and measuring equipment
• Appliances with an insufficient interference
resistance
If any other facility or equipment in the surrounding
area is affected, additional protective barriers may
become necessary.
The surrounding area to be taken into considera-
■
tion may extend beyond the boundaries of the
premises. This depends both on the type of the
building and on the other activities performed
at the site.
