Will my blue Neutrik powerCON cables work the PSU 4800 power supply?
In a word no. The PSU 4800 uses Neutrik powerCON TRUE1 is a locking waterproof 16 A true mains connector.
The powerCON TRUE1 is a connector with breaking capacity (CBC), i.e. it can be connected or disconnected under load or live – which is not recommended for the blue powerCON cable.
It also has a connection / disconnection cycle > 5000, 5 x greater than the normal powerCON.
