DC Connections for Multiple Unit Configuration
Individual overcurrent devices are to be used between the battery positive and
each inverter. Keep cable lengths to the two inverter/chargers the same in order
to balance cable losses. The battery cable between the two inverter/chargers
should not exceed 30 cm in length.
Connect the units as follows:
1. Connect the positive cables.
Follow the steps in “Connecting the DC Cables to the Inverter/Charger” on
page 1–23.
Also, do not tie the positives in series together between inverters.
2. Connect the negative cables.
Follow the steps in “Connecting the DC Cables to the Inverter/Charger” on
page 1–23.
3. Connect the battery temperature sensors (BTS), if needed.
Follow the steps in “Step 5: Connecting the BTS and Xanbus-enabled
Components” on page 1–25.
