8.2.4
Third-Party Supply Units
General Information
HMS01 and HMD01 power sections are designed to be supplied via HMV
supply units or HCS converters. In exceptional cases, other supply units
(called "third-party supply units" in the following paragraphs) can be used as
supply units (e.g., SFT from the product range RD500). Third-party supply
units cause loading which requires additional measures.
The C-UL listing of HMS and HMD applies under the condition
that they are supplied by HMV supply units or HCS converters.

Notes on Project Planning
Only HMS01 / HMD01 inverters, as well as additional components HLB and
HLC, may be operated with third-party supply units.
Requirements to the third-party supply unit:
●
Minimum inductance: In the mains connection of the third-party supply
unit, install a mains choke with at least 100 μH.
●
DC bus voltage: The DC bus voltage of the third-party supply unit must
be in the range DC 540 … 750 V. Take the limit values U
DC_LIMIT_max
of
the supplied devices into account.
●
Allowed voltage control: Sine-wave modulation with f
s
≥ 4.2 kHz.
Third-party supply units with block modulation or flat-top modulation are
not allowed.
