4.3 Connection of equipment fans for devices size 4 and 5
The following applies only to the converters DSV5444/5445 - (60), -80, -120, -150, -200, -
250/400
The fans for converters DSV 5444/5445 - 10 - 60/400 are supplied internally, so that the
terminals mentioned below are not applicable to sizes 1 – 3 and “Plus” devices.
Devices of sizes 4 and 5 from the DSV 54 series can also be supplied on request for a fan voltage of 400 V
AC instead of 230 V AC. A small autotransformer is integrated into the device in this case. Attention is to be
paid to the terminal assignment on the 4-pole power supply connector.
1) Standard (without autotransformer):
The upper pin of the connector may not be used in this case!
1-phase
230 VAC
2) Special versions with autotransformers can be supplied on request,
or is selectable possible
2-phases
400 VAC
1-phase
230 VAC
The choice of pin assignment to 400 V AC or 230 V AC is possible only when the delivered
connector has the marker "L2" on the uppermost pin.
Free pins must never be used, i.e. never use L1, L2 and N simultaneously!
Care is to be taken in the case of a 400 V AC connection, that two external fuses in the
range 2-4AT are to be provided for phases L1 and L2.
Notes on fan operation:
All sizes are provided with temperature control (fan control). The fan is normally switched on
above 40°C.
