Chapter 5, Operation<br />
5.2 Permissible operating conditions<br />
The generator may only be used, if the operation conditions listed below are<br />
kept.<br />
Only those devices may be connected, the voltage <strong>and</strong> frequency specifications<br />
of which meet the specifications given on the type plate of the generator. The<br />
generator may not be overloaded. The total power consumption of all connected<br />
devices must not exceed the output power specified for the generator.<br />
The generator must have a free cooling air supply as well as an unimpeded<br />
cooling air dissipation. The cooling air temperature must not exceed 40 °C. If<br />
the cooling conditions can not be met, the generator must not be loaded with<br />
its full rated output power.<br />
In case of inadequate cooling of the generator or under conditions other than<br />
permissible operation conditions, the generator output voltage is automatically<br />
reduced. In this case, the load connected to the generator has to be reduced to<br />
avoid damage of the connected devices.<br />
5.3 Electric protection equipment, protective measures <strong>and</strong><br />
grounding<br />
5.3.1 Electric protection <strong>and</strong> grounding/equipotential bonding<br />
If the generator is not equipped with the option "Insulation monitoring with<br />
switching-off", it fulfills the protective measure "Protection separation with<br />
equipotential bonding" according to VDE 0100, part 728.<br />
If the generator is equipped with the option "Insulation monitoring with<br />
switching-off", it fulfills the better protective measure "Protection separation<br />
with insulation monitoring" according to VDE 0100, part 728.<br />
For a proper function of the mentioned electrical protective measures, it is not<br />
required to ground the generator (e.g. using a grounding rod). If this is desired<br />
anyway or required for some special cases, a defined grounding of the generator<br />
housing can be performed or the generator housing can be included into an<br />
equipotential bonding with other devices. For this purpose, only the<br />
