Keba KeDrive D3-DA BG3 - 24 V Control Supply; Power Supply

4.6.1 24 V control supply
The supply units KeDrive D3-DP BG3 and BG4 need an external 24VDC power supply
unit for the 24VDC supply (see Figure 4.9). Details are described in the Operation
Manual KeDrive D3-DP (1804.201B.x). The 24V are distributed to the entire axis group
in the KeDrive D3 system via the busbars.

NOTE:
If an external 24 V supply is used, it must provide safe isolation as per
EN61800-5-1 or EN50178.
4.6.2 Power supply
The supply voltage for the axis controllers is supplied by the supply unit KeDrive D3-DP
via the busbars (DC link). This voltage, also called the DC link voltage, is between
565VDC and 678VDC, depending on the mains supply to the KeDrive D3-DP
(400VAC and 480VAC).
