Mechanical Dimensions
Modules may be mounted to 35mm
“T” type DIN rail (35mm, type
EN50022), and side-by-side on
17.5mm (0.7-inch) centers.
CAUTION:
IEC Safety Standards may require
that this device be mounted within
an approved metal enclosure or sub-
system, particularly for applications
with exposure to voltages greater
than or equal to 75VDC or 50VAC.
DIN Rail Mounting & Removal
Refer to the following figure for mounting and removing a module from the DIN rail.
Mounting
A spring loaded DIN clip is located on the input side bottom. The rounded edge of
the output side bottom allows the module to tilt upward so that it may be lifted
from the rail when prying the spring clip back with a screwdriver. To attach a
module to T-type DIN rail, angle the top of the module towards the rail and place
the top groove of the module over the upper lip of the DIN rail. Firmly push the
module downward towards the rail until it snaps into place.
Removal
To remove a module from the DIN rail, first separate the input terminal blocks from
the bottom side of the module to create a clearance to the DIN mounting area. A
screwdriver can be used to pry the pluggable terminals out of their sockets. While
holding the module in place from above, insert a screwdriver into the lower path of
the bottom of the module to the DIN rail clip and use it as a lever to force the DIN
rail spring clip down while pulling the bottom of the module outward until it
disengages from the rail. Tilt the module upward to lift it from the rail.
