The high power capabilities of the FOX imply requirements on the minimum
cross sections of the supply circuits. To specify the minimum cross sections
of the supply circuits PSC1 and PSC2 it has to be considered that
• the voltage at the terminal blocks “A” according to EN 300 132-2 must be
≥ |40.5 V
DC
|.
• the voltage at the FOX615 connector blocks for safe operation must be
− ≥ |40 V
DC
| with DUPF1, the voltage drop on PSC must be ≤ 0.5 V.
− ≥ |39.5 V
DC
| without DUPF1, the voltage drop on PSC must be ≤ 1.0
V.
• the FOX615 connector blocks accept cross sections of up to 4 mm
2
for
conductors of the PSC circuits.
• the maximum power rating for the FOX615 is 30 A.
