Danger to life due to electric shock in case of incorrect cable insulation
If a cable is not correctly insulated, high voltages may occur on the cable outside the inverter.
• Lead the cable into the inverter through the
silicone tube. The silicone tube must completely
cover the cable and the wires inside the
inverter enclosure.
• Cut the silicone tube to the required length, as
necessary.
• Fix the silicone tube in position with cable ties
at the beginning and end of the cable, as
necessary. Trim the ends of the cable ties. This
will prevent the ends of the cable ties causing
damage to hot components in the inverter.
