DS2020LPPA300A

Product Description

The GE Line Protection Board DS2020LPPA300A features 7 jumpers and 2 terminal blocks with 3 terminals on each. The jumpers are identified as JP1 through JP7. The GE Line Protection Board DS2020LPPA300A also contains test points. The board is installed on standoffs on another component of the drive. The signal wires that connect to the board originate on the other component.

The terminal block can connect to a maximum of 6 signal cables. To avoid confusion when you replace the board, it is critical that you identify each signal cable and where it connects on the board. Each terminal block has an ID. One ID for a terminal block is TB1 and the other ID is TB2.  Within each terminal block the individual terminals are numbered also from left to right. As an example, TB1 3 is the 3rd terminal on terminal block 1. For another example, TB2 2 is the 2nd terminal on terminal block 2. Write the ID for each signal wire on a slip of masking tape and apply it to the signal wire.

The next step is to remove the signal wires from the terminals. Have on hand a narrow flat-blade screwdriver. Select the signal wire you want to remove and use the screwdriver to loosen the retention screw. Check that about 0.5 inch of wire has its insulation removed. If less insulation is removed, use a knife to remove it. If more is removed, cut the wire so that roughly 0.5 inch is removed. Pull out the signal wire from the terminal and move it to one side.
