2.2 Connection of the Power Supply (X1)
The protocol converter requires a 24V power supply. For maximum load of the
current see chapter technical data in this manual. A three-phase rectifier or simple
rectifier circuit with charging capacitor are sufficient. The power supply must be
earth grounded.
The power supply are connected by means of a plug-in screw terminal. A 3-way
COMBICON plug from PHOENIX (MSTB 2.5/3-ST-5.08) is used.
