Installing DC Input Power Cables
Connect DC input power cables to the inverter
Insert the positive and negative battery connectors (Staubli) into the corresponding DC input terminals (BAT+ and BAT–).
The DC input terminals (BAT+ and BAT–) on the left and right sides of the battery are the same.
- Assemble DC connectors.Figure 5-11 Assembling DC connectors
For battery terminals, use the delivered Staubli MC4 positive and negative metal terminals and DC connectors. Using incompatible positive and negative metal terminals and DC connectors may burn the cables or damage the module. The resulting device damage will not be covered under warranty.
- Keep the DC input BAT+ cable and BAT– cable close to each other.
- Cables with high rigidity, such as armored cables, are not recommended as DC input power cables to avoid cable folding.
- Before assembling DC connectors, label the cable polarities correctly to ensure correct cable connections.
- After crimping the positive and negative metal terminals, pull the DC input power cables back to ensure that they are connected securely.
- Insert the crimped metal terminals of the positive and negative power cables into the appropriate positive and negative connectors. Then pull back the DC input power cables to ensure that they are connected securely.
- Insert the positive and negative connectors into the battery terminals (BAT+ and BAT-) on the switch and connect the other end to the cascaded battery.Figure 5-12 Connecting battery cables
