1
The 9 V minimum operating voltage is defined at the connector end of the input cable. Extensions and
connections to the source from the connector will increase the voltage dropped in the cabling and
consequently the minimum required operating source voltage. The supply should ideally be rated to at
least 10 A output.
2
The 5 A fuse in the auxiliary power plug is rated for 5 A continuous current with 10 A rating under
intermittent operation.
