POWERCELL Board Jumper

Two jumpers on the POWERCELL 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 2-81 shows the jumper's
locations and settings. Table 2-10 describes the purpose of each setting.
