The Pre-Charge Cable allows internal capacitors of an Inverter, Inverter/Charger or MPPT to be pre-charged via the DC terminals before connecting the Battery. This method ensures that connecting the battery will not result in an arcing at the connection point.

The pre-charge time for a Multiplus-II 48/5000 when using the Pre-Charge Cable is less than a second. Larger systems will take longer to pre-charge. The largest ssytem targeted with the Pre-Charge Cable is a 3-unit system with Multiplus(-II) or Quattro (-II). for larger systems, several Pre-Charge Cables can be used in parallel, or individual units can be pre-charged and connected to the battery one at a time

Installation:

1. Connect the battery negative to the Inverter, Inverter/Charger or MPPT
2. Do not connect the positive battery cable yet.
3. Positive Connection
   1. Connect the BAT+ Alligator clamp to the positive terminal of the battery
   2. Connect the second Alligator clamp to the positive input terminal of the Inverter, Inverter/Charger or MPPT. If needed, use a short extension wire to reach the terminal
4. Wait for the yellow LED to switch off indicating the pre-charge process is complete (see LED indications below)
5. After pre-charging, remove the pre-charge cable and immediately complete the postive battery connection.

LED Indications:

• RED LED: Indicates reverse polarity. The cable is not damaged but must be disconnected and reconnected correctly
• YELLOW LED: Lights up while pre-charging. internal capacitors are charging with a current of up to 0.5A. The LED turns off when pre-chaerging is complete and the ev ice is at battery voltage.
