MOTOR CONNECTIONS
Motor wires are connected to the driver
pack through terminals 1, 2, 3, 11, 12, and
13 on the 13-pin terminal blocks.  A typical
hookup diagram is shown in Figure 3.
Electrical connections to control inputs
should be kept physically separated from
the motor cables.
JUMPERS
The jumpers on the driver boards (vertically
mounted side boards) should NOT be
moved from the original position as
shipped from the factory.  In the event that
these jumpers are moved, replace these
jumpers to  the lower positions.
Two of the jumpers on the breakout board
(top board) are used to connect the
OUTPUTS of the CLCI500 to the Motor
ON/OFF input of the drivers.  These
jumpers are set to connect the indexer
Outputs to the driver ON/OFF inputs when
shipped from the factory.  The other two
jumpers are for use with future driver
boards.  See Table 2 and Figure 1 for details
on jumpers.
