Removing fuses

WARNING: Risk of electric shock when fuses are installed
When carrying out any work on the solar panel, loads or battery, make sure that fuses for
the solar system are not installed in the fuse terminal blocks of the control cabinet
electronics.
• Before carrying out any work on the solar system, remove the three fuses from the
fuse terminal blocks in the control cabinet in the specified order (1. Solar panel,
2. Battery, 3. Loads). This will isolate the voltage sources from the circuit.
Prior to installing the antenna, solar panels or other equipment, remove the three fuses from
the fuse terminal blocks on the control cabinet's electronics panel (see Figure 4-6 on
page 4-12).
