through which cooling water flows to cool the power sections. The size of the liquid heat sink
can be adjusted in line with the size of the drive line-up.
General conditions to be observed
1. The maximum temperature within the cabinet is 40 °C (inlet air temperature of the power
2. The maximum permissible heat sink temperature is module dependent. See the
Equipment Manual Booksize Cold-Plate Power Sections
Manual, (GH4), Edition 06.2005, 6SL3097-2AJ00-0BP2
sections). The maximum temperature within the cabinet during derating is 55 °C. For the
