Models for 208 V
The so-called US208V models are also delivered with a 5 pole AC plug. This plug is connected to 3-phase AC
supply, according to the labeling next the plug (filter housing). Required
are following phases:
Rated power
Inputs on AC plug Supply type
Configuration
15 kW
L1, L2, L3, (N), PE Three-phase (3P)
Delta
The PE conductor is imperative and must always be wired!
The N conductor, if present in the cable, can be wired to the free slot on the AC plug.
For the wiring
cross section,
the power of the device and the cable length are decisive. The table below shows

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. Connection scheme:
