1.7 Emissions and energy efficiency of the MCM 1405
ND monitor
1.7.1 X-ray radiation
The X-ray radiation generated in the monitor is adequately shielded by the intrinsically safe cathode-ray tube.
The local emissions are less than 1 µS/h (micro-Sievert per hour). The accelerating voltage is limited by the
device to a maximum of 26 kV.
The monitor conforms to the German Directive for protection against harmful X-ray radiation. The X-ray emis-
sions from the monitor conformed to the DHHS Rules 21 CFR, subsection J on the date of manufacture and
to the FCC Rules, part 15.
1.7.2 Efficiency and electromagnetic emissions
The MCM 1405 ND monitor fulfils the conditions for efficiency (to ISO 9241-3) and safety (to EN 60950).
The low-frequency electromagnetic emissions fall below the MPR II guidelines issued by the Swedish Radia-
tion Institute in Stockholm.

1.8 ESD guidelines
1.8.1 What does ESD mean?
Almost all of the modules in use today are equipped with highly integrated MOS blocks and components. The
manufacturing techniques used mean that these electronic components are extremely sensitive to overvolt-
age and thus to electrostatic discharge.
The abbreviation for such modules is
’ESD’
(E
lectrostatic Sensitive Device). This is used internationally,
although the German abbreviation
‘EGB‘
may also be seen.
The following symbol on cabinet rating plates, racks or packaging indicates that components which are sensi-
tive to electrostatic discharge have been used and thus that the modules concerned are also touch-sensitive.
ESDs can be destroyed by voltages and power levels that are far below the level that can be
perceived by humans. Such voltages occur if a person touches a component or module without
earthing themselves. Components that are exposed to such overvoltages do not generally
appear to be defective immediately - incorrect behavior starts after the component or module
has been in operation for some time.
1.8.2 Important measures to protect against static charging
Most plastics can easily become charged and must therefore be kept away from at-risk components.
Always ensure that people, the workplace and packaging are safely earthed when handling electrostatic
sensitive components.
1.8.3 Handling ESD modules
Do not touch electronic modules unless it is absolutely essential to do so in order to carry out other work. If it
is necessary, make sure that you do not touch the pins or printed conductors when you pick up flat modules.
Do not touch components unless
you are constantly earthed by an ESD wrist strap or
you are wearing ESD shoes or ESD shoe earthing strips on an ESD floor.
Always discharge yourself before you touch an electronic module. To do this, simply touch a conductive and
earthed object immediately before you touch the module (such as unpainted parts of a switch cabinet, a water
pipe, etc.).
Do not allow modules with chargeable and highly insulating materials to touch one another, e.g. plastic films,
insulating table surfaces or items of clothing made from synthetic fibers.
