CAUTION!
The installer is responsible for providing overcurrent protection.
To reduce the risk of fire, install a circuit breaker or overcurrent
device on both po) and negative(-) conductors to protect the
system.
WARNING!

A nonpolarized DC breaker is required to make sure that the battery can be
securely disconnected with from the inverter when needed.
Refer to the table below to determine the appropriate DC breaker size. The DC
load breaker selection and installation must follow the National Electrical
Code (NEC), ANSI/NFPA 70 or local electrical codes.
User can additionally earth the inverter to the enclosure of a second
earthing or equipotential bonding if it is required by local safety. This
prevents electric shock if the original protective conductor fails.
