Installation and Assembly<br />
•= Degree of protection IP 54/IP 55 – water drain holes sealed with plastic plugs<br />
If drain holes situated at the bottom are sealed, it may be expedient to remove the<br />
respective screws or plugs, depending on the ambient conditions and operating<br />
conditions.<br />
Note<br />
As a result of this, the degree of protection for IP 54 <strong>motor</strong>s is nominally reduced to<br />
IP 44!<br />

3.2.3 Installation of fans<br />
General<br />
Assembly<br />
Separately driven fan units ensure cooling of the <strong>motor</strong> irrespective of its speed.<br />
Care must be taken that the cooling air is able to flow unimpeded in through the air<br />
inlet openings and out through the air outlet openings. Discharged air must not be<br />
directly reinducted. The cooling air must be clean.<br />
Note<br />
In the case of <strong>motor</strong>s with a built-on or machine-mounted fan unit, with a built-on<br />
air-to-air cooler or air-to-water cooler, the relevant supplementary instructions must<br />
be observed.<br />
If fan units are repositioned, the arrangement of the louvered plates, filters and<br />
sound absorbers must be modified accordingly in order to maintain the cooling<br />
function and the degree of protection.<br />
If the fan unit is mounted laterally, please note the following points:<br />
•= Fan units are supplied separately.<br />
•= Do not attach the fan unit until after the holding-down bolts on the <strong>motor</strong> have<br />
been finally tightened.<br />
•= The fan unit must also be supported.<br />
