Installing 2 or 3 AC/DC Power Supply units
You can mount up to three AC/DC Power
Supply units in a vertical (recommended to use
the Wall-mount tray, heavy duty, with cable-
relief bracket, order number: 406080A-
opt.001) or horizontal position. When mounted
in a vertical position, with the connector panel
pointing downwards, the unit fulfills IP32 in
areas with more than 42 V and IP22 in other
areas. The mounting holes in the AC/DC Power
Supply are designed in such a way that units fit
nicely on top of each other when being
stacked.
The drawing shows the specifications of the mounting bolts needed when
installing two or three units on top of each other.
• 2-block mount: 4 x M6X100 mm DIN912 Ubrako
• 3-block mount: 4 x M6X140 mm DIN912 Unbrako
Important
To ensure adequate cooling of
the AC/DC Power Supplies an
unobstructed space of
minimum 5 cm must be
maintained around all sides
of the group of units (except
between the units and the
bottom side).
