Every cubicle must be provided with a power outlet for the PU. These
outlets must be wired to the distribution system, which is also used to
connect the neutral conductor for the cubicle.
The cubicle illumination should consist of incandescent lights, e.g.
LINESTRA-lamps. Avoid using fluorescent lamps as these lamps can
cause interference. If you can not avoid using fluorescent lamps you
should implement the steps outlined in the following figure.
1 Fluorescent lamp
2 Screen above the lamp
3 Screened cable
4 Switch with metallic cover
5 Line filter or screened power cable
