Information on the type label Risk of death by electrocution Potentially fatal voltage is present when the solar inverter is in operation that remains for 15 seconds after being disconnected from power. 15 seconds Never open the solar inverter. The solar inverter contains no components that must be maintained or repaired by the operator or installer.
Planning the installation Where to mount the inverter ► Always use the mounting plate supplied with the inverter. ► Check that the wall is capable of bearing the heavy weight of the inverter. ► Use dowels and screws that are suitable for the wall material and the heavy weight.
Mounting the inverter ► Fasten the mounting plate with 6 M5 screws to the wall. ► Hang the inverter onto the mounting plate. ► Check that the rail of the inverter hangs correctly in the mounting plate and screw the inverter to the mounting plate. ►...
DIN VDE 0100-712. When examining these possible fault situations in terms of the currently valid installation standards, Delta has come to the conclusion that there is no danger when operating the inverter in combination with a type A upstream residual-current device (RCD).

AC cable requirements Markings on the inverter Use properly sized wires (see table) In some countries, the following labels have to be applied on the front of each micro inverter. Please check applicable national and Wieland RST25i3S S1AZR2V local standards and regulations. AC plug BG03 (96.
Connecting to the solar modules (DC) ► Turn the DC disconnection switch to position OFF, before you DANGER connect the DC cables. High electrocution Potentially fatal voltage may be applied to the DC connections of the solar inverter. When light is falling on solar modules, they immediately start producing energy.
