·The DC voltage can be up to 750 V. The unit may only be opened by a qualified electrician!

·Always disconnect the PV generator side first by opening the PV generator switch, and then the grid connection by isolating the relevant mains fuse!

·If you do not have a PV generator switch

in your PV system, you must disconnect

EN

the grid connection first of all by isola-

 

ting the relevant mains fuse. However, a

 

«grid error» will be entered in the error

 

memory of the solar inverter!

 

·Disconnection of the PV generator by removing the TYCO SOLARLOK DC con- nectors must never be performed under load. In the event of non-compliance, the connectors could be damaged by a strong electric arc. In this case, the relevant con- nectors must be replaced!
