Installing the Second Level (Stacked) Modules
NOTE
It is difficult to set the switches of the first level modules and connect the
RS-485 cables once the stacked modules are installed.
The S300 expansion enclosures support a stacked configuration for modules.
However, after stacked modules have been installed, it is difficult to reach the first
level modules for purposes of switch settings or wiring.
To stack modules, perform the following steps:
1. Remove the four screws holding the module to the enclosure back
.
2. Secure the first level module with the 2 inch standof
fs supplied in the kit in
place of the screws removed in step 1.

3. Secure the stacked module in place with the four
screws removed in step 1.
You can install stacked modules in the locations shown in Figure 3-11 through
Figure 3-13. Only use these locations, because room must be left inside the cabin
et
for the door to close with th
e backup battery installed.
