2.2 Safety instructions:

1. PEFS is an electrical product that should be installed by a suitable person who meets local regulations.
2. When modifying an existing installation, isolate the inverter from the PV array by turning OFF the DC isolator/switch disconnect or turning OFF the inverter and the AC switch.
3. Incorrect connections to the PEFS-24V-CN may cause failure.

2.3 Cautions:
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.
