There are two M-module mounting locations on the EM405D. Single-wide M-modules may be
installed in either or both of the positions. A double-wide M-module will occupy both positions.
The EM405D configuration is illustrated in Figure 3.
Figure 3. M/MA Configuration Diagram
CAUTION: M-module connectors are NOT keyed. Use extra caution to
avoid misalignment. Applying power to a misaligned module
can damage the M-module and carrier.
Re-assemble the EM405D by first sliding the carrier into the enclosure. Be careful to align the
edges of the carrier with the guide rails of the enclosure. Improper alignment will cause the back
panel component to not align with the back panel cutouts. Slide the carrier all the way into the
enclosure and re-affix the front panel using the two screw holes located at the sides of the panels.
