The keypad power, aux power, smoke power... are separately fused with a PTC ( positive temperature coefficient) resetable breaker. You can not draw from each output the fuse rating. You will overload the power supply if you do this. The total supplied current from the M1 must be calculated by adding together the current from each device connected to a power supply outputs.
An interesting note on resettable PTC breakers, if you short out a breaker, it gets hot and shuts down. The current load must be reduced to a point that the PTC can cool down before it will reset. Sometimes you have to turn off the controls power and wait a minute to allow the PTC to cool down before it will restore itself. The plug in transformer is the same way. If you have overloaded the plug in transformer and it shuts down, you will have to wait several minutes for the transformer steel to cool down so the the PTC will reset.
