The equipment should draw power from a socket with an attached protection circuit (a
three-prong socket). All equipment that works together (computer, monitor, printer,
and so on) should have the same power supply source.
The phasing conductor of the room’s electrical installation should have a reserve
short-circuit protection device in the form of a fuse with a nominal value no larger than
16 amperes (A).
To completely switch off the equipment, the power supply cable must be removed
from the power supply socket, which should be located near the equipment and easily
accessible.
A protection mark “B” confirms that the equipment is in compliance with the protec-
tion usage requirements of standards PN-93/T-42107 and PN-EN 55022: 1996.
