2.
Select a location for mounting the ambient temperature sensor ring lug. The temperature of this mass should have a fairly long
thermal time constant (e.g. temperature should not cycle with short-term temperature changes due to normal environmental
heating and cooling cycles). Typically this could be a nearby equipment rack the Sageon III system is mounted adjacent to.
3.
Fasten the ambient temperature sensor to the selected point using appropriate user-supply hardware.
4.
Route the 4 battery temperature sensors to the battery string(s). Typically somewhere close to the string midpoint.
5.
Determine which battery posts will have sensors attached. Suggested location is shown in the battery string drawing, figure 2-14.
Note: The highest of the four battery temperature readings is used for compensation. Locate a sensor at the warmest battery,
generally one at the center of a battery group.
6.
Determine the charge/discharge status of the battery string. Connecting the sensors may result in a momentary battery string open
circuit when the terminal bolt is removed.
CAUTION: DO NOT
proceed if the battery string is being charged or discharged at a high rate. Continue only when the charge
or discharge rate is at a safe level.
7.
Remove the bolt holding the inter-cell battery strap in place. Insert the bolt through the battery temperature sensor ring lug,
through the strap, and into the battery terminal. Tighten the bolt as recommended by the battery manufacturer.
8.
Repeat steps 6 and 7 to install the remaining battery temperature sensors.
9.
Bundle and secure excess wiring.
10.
Enable compensation using the operator panel push buttons and menus or a PC running SageView.
11.
If installing the Sensor Kit, get the compensation chart label. Remove the backing from the label and place the label on the inside
of the distribution area door.

2.10 INSTALLING A BATTERY CURRENT TRANSDUCER (OPTION)
The optional battery current transducer senses the battery current for display on the operator panel. When installed, the battery current
transducer also allows the user to configure the SCU to limit the recharge current to the battery string in order to extend battery life;
and set a fixed, repeatable discharge current for battery discharge tests.
Install one battery current transducer per battery string (up to four transducers). If not ordered with the Sageon III Power System, a
Battery Current Transducer Kit is available.
