C445 Mounting
To aid with the panel layout of the Power Xpert C445
modules, refer to the dimension drawings.
The C445MB… Base Control Module and the C445M…
Measurement Modules are designed to be mounted utilizing
a standard 35 mm DIN rail or utilizing a panel mount method.
When mounting the modules on 35 mm DIN rail, ensure that
the rail is properly secured to support all devices installed on
the rail.
All C445 devices may be panel mounted The C445B… base
module and C445MA… Measurement Module utilize
optional mounting feet that are snapped into place. A
minimum of two (2) mounting feet are required. Tabs are
installed at locations so one tab is on the top and one on
the bottom of the device when mounted vertically.
C445MB… and C445MC… Measurement Modules have
mounting tabs molded into the housing assembly.
Installation of panel mount screws on all mount tabs are
required.
The C445B… base module may be installed directly on top of
the C445MA… Measurement Module by aligning the mating
slots of the two devices and snapping them together. If the
two devices are to be panel mounted, all four(4) panel mount
tabs are required.
Table 6. Mounting Hardware
The C445B…/C445MA… combined assembly may be mounted on a 35 mm DIN-Rail.
