Each DC power supply has a single DC input (–48 VDC and return) that requires a
dedicated customer site circuit breaker. We recommend that you use a dedicated
customer site circuit breaker rated for 40 A (–48 VDC) minimum, or as required by local
code.
For high capacity power supplies, we recommend that you provision 60 A or 75A per
feed, depending on the selected DIP switch setting.
