Structure:
A solid heat sink with two sidewalls and a cover made
of metal form the equipment assembly.
The semiconductors are mounted on the heat sink and
electrically connected with the printed circuit board,
which is fastened on top of it.
The terminals are at the front side of the unit.
Installation:
The site of installation must be dry and free of dust.
Mounting:
Power module is designed for wall or rack mounting.
For optimal cooling a distance of approx. 200 mm
around the unit must be kept free.
Dismantling the cover:
Both system plugs X102 and X103 are to unbolt
and to remove.
Subsequently, unbolt the four screws on the cover.
Now the cover can be raised and removed from the
side of the connector.
