Humidity indicator<br />
card<br />
A small bag of desiccant is mounted inside each door of the<br />
2191EX, and inside the right door of the 2196EX. A humidity<br />
indicator card is attached above each desiccant bag. The<br />
humidity indicators have regions that display 20, 30, and 40<br />
percent humidity levels. Ideally, each region should be completely<br />
blue. As the desiccant bag becomes saturated, the<br />
humidity levels will increase, and the regions turn pink. When<br />
the 40 percent region turns pink, the battery module is no longer<br />
adequately protected, and the desiccant must be replaced. Refer<br />
to Section 5.4 for replacement instructions.<br />
2.4.3 Assembling the System The 2100 Series System is modular; you build the system by connecting<br />
modules together. The instructions in this section<br />
describe how to connect a <strong>2150EX</strong> module to a 2196EX or<br />
2191EX battery module in its most basic configuration — by<br />
stacking the two modules. The battery module must be at the<br />
bottom of the stack.<br />
You can use multiple modules in a stack to increase the site’s<br />
functions. A maximum of two <strong>2150EX</strong> modules may be powered<br />
by one battery module, to avoid overloading the batteries.<br />
However, within a stack, you can have multiple sets of<br />
<strong>2150EX</strong>/battery module combinations.<br />
Connection options<br />
Keep in mind that stacking is not the only way to connect<br />
modules. The modules may be placed in remote locations and still<br />
operate as a single site. If you would like to use remote modules<br />
for your application, please consult with the factory or your representative<br />
to realize the full potential of your system.<br />
