Regen Dump Circuit Connections
DC Power Source Connections
The regen dump circuit is recommended for all BOSS Series
drives. Regenerative loads may cause the bus voltage to
increase. The regen dump circuit prevents the voltage
across the bus capacitors from exceeding their voltage
rating.
If you use a DC power source with the regen dump circuit,
you must connect the power source to the BOSS drive L1
and L2 terminals as shown in the figure above.
1. Connect the +BUS terminal on the regen dump circuit to
the +VDC terminal on the BOSS drive motherboard.
2. Connect the -BUS terminal on the regen dump circuit to
the -VDC terminal on the BOSS drive motherboard.
BOSSDB Series Regen Dump Circuit Dimensions
All dimensions in Inches [Millimeters]
1. Connect the positive (+) lead from the DC power source
to the L1 terminal on the BOSS drive motherboard.
2. Connect the negative (or COM) lead from the DC power
source to the L2 terminal on the BOSS drive
motherboard.
