4.2 Mount
The PSTX30...370 softstarters are available in three
different physical sizes and all of them should be mounted
with M6 bolts, or bolts with the same dimension and
strength.
4.2.1 Handling when mounting
WARNING
Do not lift the softstarter by the connection bars,
as this can damage the softstarter.
PSTX30...370 can be taken out of the package and be
mounted without lifting equipment. See 3.2.4 Weights
for weights.
4.2.2 Minimum distance to wall/front
Make sure that the distances to the surrounding
walls are sufficient. For the minimum distance to
front and wall, see Figure 16 and Table 2.
WARNING
Risk of damage to property. Ensure that no
liquids, dust or conductive parts enter the
softstarter.
WARNING
If you do not obey these instructions, this can cause
the softstarter to become overheated or not operate
correctly.
To get suitable cooling, the softstarter has to be mounted
vertically, and in such a way that the airways are not
blocked, see Figure 14.
