3-26 Installing the Drive 590 Series DC Digital Drive
Re-Wiring Procedure
WARNING
Isolate all power to the drive.
1. Loosen the control board fixing screws (2 off) and position the control board to allow access to the power board.
2. Remove the red link from the Faston connector “F16” on the left-hand side of the board and connect it to staging post “F19”, located below
terminal D1.
3. Remove the yellow link wire from the Faston connector “F8” on the left-hand side of the board and connect it to staging post “F18”, located below
terminal D2.
Caution
When using an external ac input it is important to have the correct phase relationship on the terminals.
The supply must be derived from L1 (Red) and L2 (Yellow) phases directly or indirectly through a transformer.
L1 must be connected to D1, and L2 connected to D2.
The external field supply can now be connected and power restored to the drive.
Power Board - PCB Reference 385128
External Motor Field (default for this board)
This power board (printed with the above number) is supplied in external stack
options using an external motor field supply. Connect the external supply to
busbars FL1 and FL2. The motor field output is taken from busbars F+ and F-.
You should provide suitably rated external, fast-acting semi-conductor fusing, to
a maximum of 20A.
