Jumper Settings

Two jumpers on the POWERCELL MTX board are designed W1 and W2. If the application contains
more than 14 POWERCELLs, an external Power Supply (P/N 0917-0240) must be connected on
pins 9 and 10 of the board connector, and jumper W2 should be in the 24V position. Figure 2-45
shows the jumper's locations and settings. Table 2-9 describes the purpose of each setting.
