Note These connections are not necessary for normal operation of the drive.
Following paragraphs are only valid when the control card is used on frames B, C & D:-
Connection can be made from a suitable, external 24V source. This 24V DC control supply allows for
configuration and commissioning of the system without the AC supply being present. The drive will
operate with this supply but will not turn a motor.
Connection is not required when the AC supply is present, but the connection can be safely left connected.
You can connect up to four 890SD units in total when daisy-chaining 24V using these terminals (8A
maximum). If you have more than four 890SDs, use a 24V rail and wire as shown in the Wiring Diagram
on page 5-11.
