Page 3: Operation Principle
1.2. Operation principle. AWZ 333 is a stabilized transformer power supply unit with a high line regulation. Line voltage ~230V, is lowered with the use of transformer and then it is recertified by a rectifier circuit and a low-pass filter. DC output voltage comes from a line stabilizer. Output voltage is corrected depending on power supply unit operation mode (charging mode battery maintenance). -

Page 8: Installation Procedure
2 Installation procedure. 1. Before installation make sure that the mains 230 V is disconnected. 2. Install the power supply at the selected place and evacuate connection wires. 3. Remove the main fuse protecting the transformer primary circuit [15]. 4. Connect the supply conductors ~230V to the terminals of the AC 230 V transformer [14]. The earth conductor should be connected to the terminal marked with the grounding symbol [16]. -
