3.10 Voltage Supply of the Fans at Dimension 4 and 5
On request becomes the devices of the DSV 54** -series in the size 4 and 5 too for an fan voltage of 400
VAC equip delivered as up to now 230 VAC. A small autotransformer is integrated into the device. Dimension
5 is a new dimension which covers the range from 75 kW up to 100 kW.
Considering is the pin assignments at the 4-pole supply connector:
1)
Standard (without autotransformer):
The most uppermost Pin of the connector must not become engaged here!
2)
Version "Focus dynamics" (with autotransformer, devices as from 01.05.99):
Important:
Only if the supplied connector has the denotation "L2" at the most uppermost pin, the selectable
pin allocation is possible with 400 VAC or 230 VAC!
Considering is with the 400 VAC connection, that two external fuses between 2AT and 4AT are to be planned
for the two phases L1 and L2.
Free pins may never be engaged i.e. never engage L1, L2 and N!
