Utility connection:
1. Risk of electric shock! The utility input can generate dangerously high voltage! Disconnect the
circuit breaker or fast-acting fuse before wiring, and ensure that the pole leads are connected
correctly.
2. After the utility is connected, the battery cannot be grounded. In contrast, the inverter cover
must be reliably grounded to shield against outside electromagnetic interference effectively and
prevent the cover from causing electric shock to the human body.
