Eaton Electrical SC200 manual Applying DC Power to the Load

Commissioning

Applying DC Power to the Load

1Check the DC output voltage and polarity of the power system and battery string(s).

2Switch on the Battery MCB(s) (if fitted) and check that the Battery Fuse Fail alarm clears.

When connecting multiple battery strings in parallel to the system DC bus, ensure that the individual strings are of similar voltage.

3Check the Battery Current reading, if batteries are fitted. (The actual value depends on the state of charge of the batteries.)

4Switch on the Load MCB(s). Check that the load (the equipment) powers up and that the Load Fuse Fail alarm clears.

5Check the rectifier currents and verify that the load current is representative of what the load draws and also that the power system has sufficient capacity.

6Charge the batteries (if fitted) according to the battery manufacturer’s recommendations. Manual Equalize can be started from DCTools or the front panel.

Manual Equalize increases the system voltage to the pre-configured equalize voltage for the pre-configured equalize duration. After the pre-configured equalize duration has expired, the power system voltage reverts back to normal battery float voltage automatically.

7Fit the DC output cover.
