Operation with a Voltage Protection Module
Note
Electromotive force > 820 V
Depending on the amplitude of the induced phase-to-phase voltage at maximum speed
(synchronous generated voltage > 820 V), a Voltage Protection Module (VPM) may be
required; see Chapter "Voltage limiting".
Operation with a series reactor
A series reactor with the appropriate inductance is required for the following 1FE1
versions to ensure safe and reliable operation:
1FE1052-4HD..
1FE1052-4HG..
1FE1053-4HH..
We recommend that reactors from the mdexx company (www.mdex.com) are used with
the following order designation:
0.23 mH
0.32 mH
Technical data and dimension drawings for the series reactors are provided in the
Appendix underTechnical data and dimensions of the recommended series reactors
(Page 137).
The drive system setting data, as well as the electrical power data, are only applicable in
conjunction with these reactors.
Note
The specified data cannot be guaranteed when using other reactors.
Burn injuries due to hot surfaces
The surfaces of series reactors can reach temperatures of > 100 °C.
• Do not touch hot series reactors with your bare hands.
• Carefully ensure that temperature-sensitive components are an adequate distance
