Mains Connection for Programmers
Provide a power connection for the programmer in each cabinet. The plug must be supplied from
the distribution line to which the protective ground for the cabinet is connected.
Cabinet Lighting
Use, for example, LINESTRA® lamps for cabinet lighting. Avoid the use of fluorescent lamps since
these generate interference fields. If you cannot do without fluorescent lamps, you must take the
measures shown in Figure 3.38.
