Connect the power through P+ and P- .
Connect the first High-voltage box Link Com Terminal to the inverter
BMS port for communication beween inverter and battery.
Ensure power cables are installed with the correct polarity.
A dangerous situation may arise if the polarities are
reversed.
Do not create a short circuit between the positive and negative
terminals of the battery. Ensure the polarity is
correct during installation.
Incorrect communication cable connection will cause the
battery system to operate in unexpected ways which
may lead to system failure.

6. Maintenance
5. Commissioning Procedure
After all the cable (power and communication) connections are completed, please ensure
the following:
• Ensure the DC switch on the inverter is OFF
• Ensure the AC switch that is connected to the grid and EPS output (if used) of the
inverter is OFF
• Ensure the DC switch on the HV box is OFF
For commissioning we recommend the following steps:
• Turn the DC switch on the HV box ON
• Refer to section 2.3.2 Start for turning on the battery
• Wait until the HV box LED´s on
• Wait until the inverter LED´s on
• Turn the DC switch on the inverter ON
• Turn the AC switch that is connected to the grid and EPS output of the inverter ON
• Set-up the battery and the inverter using the App
