WIRING DIAGRAM
The braking unit must be connected to the inverter and the braking resistor.
The braking unit is connected directly to the inverter terminals (or copper bars for sizes greater than S40) of the
DC output, while the braking resistor must be connected to the inverter on one side and to the braking unit on
the other side.
The wiring diagram is shown in the figure below:
Figure 58: Connecting one BU200 to the inverter.
NOTE!!
The braking resistor must be connected between terminal B of BU200 and
te of the inverter. In that way, no sudden variation in braking current
occurs in the supply line between the inverter and BU200. In order to minimize
electromagnetic radiated emissions when BU200 is operating, the loop obtained
from the wiring connecting te of the inverter, the braking resistor,
terminals B and - of BU200 and terminal - of the inverter should be as short as
possible.
NOTE
Install a 50A fuse with a DC current of at least 700 Vdc (type URDC SIBA series,
NH1 fuse) provided with a safety contact.
CAUTION
Link the safety contact of the fuse being used with the external alarm of BU200.
