Electrical Connection; Battery Connection - Redx RX Series User Manual

An independent circuit breaker must be configured for each power interface.
The table below is a recommendation for cable selection and the Recommended specifications
of circuit breaker. Engineers should refer to local standards to select cables. Cable length
is generally 2 to 10 meters, long cable will lead to voltage deviation from the rated value,
consequently requiring an increase of the cross-sectional area.
