3.11 Paralleling T200-X10 Units through the D.C. Bus
T200-X10 units can be paralleled via the D.C. Bus, in order to share regeneration power. In Figure 3.19, below, the
T200-X10 units are shown with the a.c. mains inputs connected to all T200-X10 units. The user can also connect the
D.C. Bus outputs of the T200-X10's at TB3 in order to share regeneration power.

CAUTION:- If a T200-X10 unit does not see a high a.c. voltage at pins 1, 2 or 3 of
terminal TB2, then the T200-X10 will continuously activate the fast bus discharge.
This will cause damage to the internal regeneration circuitry, if a high d.c voltage is
present at connector TB3. The T200 will then have to be returned to the factory for
repair.
