5-10 ADS Manual
Mounting the ExPAC
Note: For applications involving an XIO or XBUS, you
can disregard these instructions for mounting the ExPAC
because both the XIO and XBUS come from the factory
with the ExPAC pre-mounted to a DIN rail inside the
XIO/XBUS enclosure.
Mount and secure the ExPAC in such a way that takes into account
the specific environment in which the unit will be located. For
outdoor installation, mount it inside a secure, weatherproof
enclosure (minimum NEMA IP66) that will provide the best
protection against the elements and excessive heat or cold. The
operating temperature range for the ExPAC is -4

to 122

F (-20

to
50

C). Therefore, make sure the enclosure is also located under an
awning or other structure to prevent direct sun exposure. For
indoor installation, mount the ExPAC inside an enclosure or in a
location that prevents tampering or potential damage from
occurring.
The ExPAC is designed for mounting on a 35- x 7.5-mm DIN rail
or securing to another surface or structure through the four
predrilled holes on the sides of the unit.
Mounting the ExPAC to a DIN Rail
Mount the ExPAC to an existing DIN rail in an enclosure or on a
rack in the following way:
1. Make sure the red, plastic tabs on the back of the ExPAC are in
the open (or
extended ) position. To open the tabs, insert a
flathead screwdriver into the inset on the triangular portion of
the tabs (from the front of the unit) and press upward until it
clicks and pops up slightly.
