Supporting measures for avoidance of EMC problems:
a) Requirements for the mains connection
-
if electromagnetic interference arises despite correct mains connection,
additional measures are necessary (e.g. use a suitable line filter).
-
High-performance devices can affect the quality of mains voltage through
their current input. For certain types of device, therefore, there may be
special application restrictions or minimum requirements in respect of the
maximum permissible mains impedance (see Technical data). In this
event the plant operator (if appropriate after consultation with the power
supply company) must check whether the connection conditions are
appropriate.
b) Current-carrying cables and leads should be
-
keep leads as short as possible
-
allow them to run closely together (to avoid EMF problems)
-
keep them far from other leads
c) Potential equalisation
d) Earthing the workpiece
-
If necessary, establish earth connection using suitable capacitors.
e) Screening, if necessary
-
screen off other devices nearby
-
Screen off entire cutting installation
Electromagnetic fields may pose as yet unknown risks to health:
-
effects on other persons' health, e.g. those with pacemakers and hearing
aids
-
Those with pacemakers must seek advice from their doctor before
approaching the device or any cutting that is in progress
-
For safety reasons, keep distances between the cables and the
operator's head/torso as great as possible
-
Do not carry cables or hosepacks over the shoulders or wind them round
any part of the body
ensure that all covers are closed and all side panels are fitted properly.
Keep all covers and side panels closed.
When there is steam escaping from the cutting torch, this represents a
serious risk of injury (scalding of hands, body, face, eyes, etc.). The cutting
torch should therefore be held away from the body at all times.
