DC Connections for Multiple Unit Configuration
Individual overcurrent devices are to be used between the battery positive and
each positive cable leading to the DC Switchgear. Keep cable lengths to the two
DC switchgears the same in order to balance cable losses.
Connect the units as follows:
1. Connect the positive cables.
Follow the steps in “Connecting the DC Cables to the DC Switchgear” on
page 1–25.
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 DC Switchgear” on
page 1–25.
3. Connect the battery temperature sensors (BTS), if needed.
Follow the steps in “Step 5: Connecting the BTS and Xanbus-enabled
Components” on page 1–27.
