2.1 Starting the ESCR
All equipment is shipped from the factory fully tested and adjusted based on the factory settings listed below.
Before connecting the battery, verify the recommended voltage settings with the battery manufacturer and adjust
the output settings accordingly. Failure to match the charger settings with the connected battery may damage
or shorten the life of the battery.
Factory Settings

2.1.1 Checking the Installation
Before starting the ESCR, verify that all connections are correct and all terminations are securely tightened. Verify the
input voltage, frequency, and output voltage is correct per application against the nameplate ratings of the charger.
2.1.2 Starting/Stopping the ESCR
Once proper connections are established, energize the charger by applying AC input voltage. This will charge the
capacitors inside the unit and eliminate heavy arcing when the batteries are connected. Shut down the charger by
removing AC input voltage, then the batteries.
2.1.3 Start-Up Sequence
Upon powering up the ESCR, the LCD will display the model and software number. During the startup sequence, the Low
DC voltage alarm will be temporarily activated.
