PS 9000 3U Series
2.3.4.2 Models for 208 V
The equipment is delivered with a 4 pole mains plug. Depending on model, this will be connected with a 2-phase
or 3-phase mains supply, which has to be connected according to the labelling on the plug and the table below.
Required for the mains connection are following phases:
Nominal power Phases Supply type
5 kW L2, L3, PE Three-phase
10 kW L1, L2, L3, PE Three-phase
≥15 kW L1, L2, L3, PE Three-phase
The PE conductor is imperative and must always be wired!
For the sizing of wiring cross section, the power of the device and the cable length are decisive. The table below
gives the maximum output current for each phase.
Based on the connection of a standalone unit:

10 kW AWG 8 56 A AWG 8 32 A AWG 8 32 A AWG 8
15 kW AWG 8 56 A AWG 8 56 A AWG 8 56 A AWG 8
The included connection plug can receive lose/soldered cable ends of up to 16 mm² (AWG 6). The longer the
connection cable, the higher the voltage loss due to the cable resistance. Therefore the mains cables should be
kept as short as possible or use bigger cross section.
