The nominal power is indicated on the nameplate. AC motors that have been designed for a
nominal power of 400V can be used in the range of 400V + 6 / -10% in accordance with DIN/IEC
38. Also in accordance with this, single-phase motors can be used in the range of 230V 6+/-10%.
Connection EVA ethylene vinyl acetate 4 GJ1 according to VDE 0208 / 3.69. This cable is approved
for supply voltages up to 500V, the thermal resistance has a maximum of 120 °C. The line structure
corresponds with VDE 0282 part 804.
All engines have a protection by means of thermal contacts. Exceeding the temperature limit of 135
°C (for example, due to high ambient temperature or heating with high water temperatures) will set
these into action and turn off the engine.
This engine protection is only achieved with our own switching gear. Using other brands will end
the warranty of the engine.
Important: switching capacity: 10 A with cos = 1,0
6 A with cos = 0,6
Voltage: 250 V
Voltage power: 2000 V eff.
If the engine protection is in operation, the engine can only be set to zero after cooling down and
returning of the selector, if the switching unit is in operation (except switching unit 670,1). After
connection, check the direction of rotation of the fan. The fan runs well when air comes out of
the frame. Changing the direction of rotation can be done by interchanging the two phases. When
connecting the switching units and engines, local regulations must be taken into account.
Connection isolating switch see chapter 6.2.
