Note
If you are connecting a redundant AC power supply, ensure that each power supply is connected to a
separate power source in order to prevent power loss in the event of a power failure.
When installing DC power supply, use 14AWG for longer cables and 14-16AWG for shorter cables,
90°C temperature rated cable. The recommended cable length is three meters maximum from source.
• Always ensure that the building's installation for short-circuit (overcurrent) protection does not
exceed 15A.
• We recommend you to use a circuit breaker or a fast acting fuse with a maximum DC rating, based
on the router variants for over current protection.
