Important Safety Precautions
PROJOY assumes no responsibility for any loss, in particular for circuit damage, resulting from any violation of the specifications recommended and referred to in this specification. PROJOY assumes no responsibility for the damage of the product caused by the maintenance, improper use, wrong installation or wrong system design of the product by non-designated personnel.1) PEFS is an electrical product that should be installed by a suitable person who meets local regulations. When modifying an existing installation, isolate the inverter from the PV array by turning OFF the DC isolator/switch disconnect or turn OFF the inverter and the AC switch. Incorrect connections to the PEFS-24V-CN may cause failure.If the inverter and pv module connectors are not compatible with PEFS connectors, forced connections are unsafe and may cause operational problems. For the mechanical compatibility of the module/converter and PEFS, use the same connectors from the same manufacturer on both the PEFS and modules, or obtain verification that the connectors to be used are compatible.
