3.1.1 Checking the Installation
Before attempting to start up the TPSD2, check and verify that all connections are correct. Check that all
terminations and contacts are tightened securely. Check for any loose connection or unsecured components in
the charger. Check that the transformer is set for the correct input voltage and that the input frequency matches
the nameplate or the charger. Check that the battery/load voltage matches the DC output voltage on the
nameplate of the charger. Verify AC feeder breaker matches charger input protection rating.
