PS 9000 3U Series
2.3.4.3 Connection variants
Depending on the max. output power of a certain model, it requires two or three phases of a three-phase AC sup-
ply. In case multiple units with 3.3 kW to 10 kW power rating are connected to the same AC supply point, it is
recommended to take care for balanced current distribution on the three phases. See table in 2.3.4 for the max.
phase currents.
The 15 kW models are an exception, because they already consume balanced current on all three phases they
require. As long as only such models are installed, no unbalanced AC load is expected. Systems of 15 kW models
mixed with 10 kW models (note: the 10 kW model PS 9040-510 3U is internally congured like a 15 kW) or models
with lower power are not automatically balanced.
Suggestions to assign phases:
Single unit (3.3 kW / 5 kW)
Multiple units (3.3 kW / 5 kW) Multiple units (6,6 kW / 10 kW)
