4. Operation and Charging
4.1 Determine Charging Voltages
Your Tripp Lite UPS is already set up for proper float and boost voltages from the factory.
4.2 Initial Charge
Proper amp-hour rating and charge current must be manually input into the UPS
set-up. Refer to the Tripp Lite UPS Owner's Manual for details.
4.3 Operational Check
1. Measure and record the total system float voltage. Measure at the battery terminals.
2. Measure and record the system float current using a clamp-on ammeter.
3. Measure and record the float voltage of individual battery units.
4. Measure and record the temperature of several batteries. Measure battery
temperature with a digital thermometer by placing the surface thermocouple on the
flat surface of the negative terminal—not the "L" connection surface. An infrared
temperature monitor may also be used.
5. Optional: Perform impedance and conductance tests on individual battery units.
These tests require special equipment, but the data can be useful in trending the
system over time or identifying suspect units during later periodic checks. It may
be necessary to disconnect the battery system from the charger/load during these
checks.
