check the residual DC voltage with a volt- meter. Then you may work on the termi- nals. See chapter 2.1.
·Always disconnect the PV generator side first by opening the PV generator switch; then interrupt the grid connection by iso- lating (switching off) the corresponding grid fuse!
·Never disconnect the PV generator by pulling out the Tyco Solarlok connectors under load. Otherwise a powerful electric arc might damage the connectors. The damaged connectors then have to be replaced!
·If your PV system does not have a PV generator switch, interrupt the grid con- nection by isolating (switching off) the corresponding grid fuse first. A fault will then be recorded in the fault memory of the Solar Inverter, however.
