4.2 Requirements to be met by the place of installation <strong>and</strong> use<br />
Single-bearing generators are mounted directly to the engine. These generators<br />
may only be mounted to engines which comply with the applicable regulations,<br />
rules <strong>and</strong> requirements.<br />
Two-bearing generators are usually installed right next to the engine. The<br />
generator has to be firmly <strong>and</strong> securely mounted on an absolutely flat base with<br />
a bearing capacity adequate to the weight class of the generator. When using a<br />
belt drive, it is advisable to mount the generator adjustable. For that purpose<br />
e.g. mounting rails can be used, providing the possibility of adjusting the belt<br />
tension.<br />
All generators are splash-proof according to IP54 specifications <strong>and</strong> can thus<br />
also be mounted <strong>and</strong> used outdoor. The generators are not explosion-protected<br />
<strong>and</strong> thus must no be used in explosive atmospheres. Further regulations on this<br />
have to be observed!<br />
When selecting the place of installation <strong>and</strong> use, the required minimum<br />
clearances have to be observed, adequate ventilation has to be ensured at any<br />
time, <strong>and</strong> the temperature of the cooling air must not exceed 40 °C.<br />
The generators <strong>and</strong> the parts mounted to them must not be sprayed with highpressure<br />
cleaners. Therefore, the generators should preferably be installed in a<br />
way <strong>and</strong> place which makes it impossible to even inadvertently spray the<br />
generator with high-pressure cleaners.<br />
4.3 General regulations for installation<br />
A correct <strong>and</strong> proper installation of the generator is a prerequisite for a safe,<br />
reliable <strong>and</strong> error-free operation as well as the electrical <strong>and</strong> mechanical safety.<br />
Usually the generators are operated with a counterclockwise direction of<br />
rotation. In this case the output voltage has a "clockwise rotating field".<br />
However, the generators can also be operated with a clockwise direction of<br />
rotation. Then the output voltage has a "counterclockwise rotating field".<br />
Due to the dynamic processes during the switching of electric loads, the engine<br />
must have adequate power reserves <strong>and</strong> its governor system must be able to deal<br />
with such processes.<br />
The constructional form <strong>and</strong> design of the generator must not be changed.<br />
Mounting surfaces must be precisely flat. Misalignments during installation have<br />
to be avoided.<br />
