5.1.10 EVR Cabling (optional)
With the Sunny Centrals 350 and 500, the EVR resistor has to be mounted on top of the Sunny
Central. Proceed as follows:
1. The EVR resistor between the rails has to be pushed onto the roof of the Sunny Central.
2. 9 screws at the protective bar of the EVR resistor have to be removed.
3. Protective bar has to be taken off to the front.
4. Connect the grounding cables in EVR resistor to the left side of the bolt (torque 21 Nm).
5. Fix the EVR resistor with both screws on the left and right side of the EVR resistor onto the rails.
6. Connect the power cables using the provided circuit diagram (torque 21 Nm).
7. Fix the protective bar with 9 screws onto the EVR resistor (torque 2.6 Nm).
☑ The EVR resistor is installed.
