<strong>2150EX</strong> Area Velocity <strong>Flow</strong> System<br />
Section 2 Preparation and Installation<br />
Note<br />
During the charging process, the 2196EX case must remain<br />
open, exposing the desiccant to the atmosphere. Teledyne<br />
<strong>Isco</strong> recommends storing the desiccant in an airtight container<br />
while charging the batteries. Check the humidity indicator on<br />
the inside of the door whenever it is opened and ensure that<br />
only dry desiccant is installed when re-sealing the case.<br />
The charging terminals are located on the circuit board mounted<br />
on the inside of the left compartment door (Figures 2-7 and 2-8, +<br />
and –).<br />
CAUTION<br />
The circuit board is permanently connected to the interior of<br />
the module. Use care when opening the case that the wires<br />
are not damaged.<br />
During charging, the yellow LED on the circuit board remains on<br />
to indicate charge voltage in correct polarity. The replaceable 2A<br />
fuse on the back side of the board protects against excessive<br />
current.<br />
