Mechanical fixing
The PP420 can be mounted onto a flat surface using the M4 clearance
mounting holes in the corners of the base or the M4 threaded holes in the
centre, see the diagram below.
Note:
If you choose to mount the PP420 using the threaded holes, ensure
no more than 6mm of thread can be screwed in.
The PP420 should only be mounted either vertically or with its base
horizontal. It should be mounted at least 15mm away from the sides of
plastic enclosures. Likewise leave a similar space between the PP420 and
any parts which could be affected by high temperatures.
The enclosure of the PP420 is used to dissipate power in the form of heat.
For this reason the material to which the unit is attached must be suitable,
preferably metallic with ability to dissipate the produced heat. This is
particularly important if the power dissipation of the PP420 (as defined by
P
D
in
Section 12, Reference information
) exceeds 8 Watts.
The PP701 kit is available for mounting the PP420 on a DIN rail.
The PP420 does not have an IP rating and should be mounted so that
moisture and dirt cannot enter the unit.
