5.5 - Mains chokes
POWERDRIVE MD2CS must be connected to an
ac line reactor.
a second line reactor can be added to reduce
the harmonics of the line current. In this case, two identical
reactors are connected in series.

5.6 - Associated braking module and
resistors
Braking phases occur when energy is sent back from the
motor to the drive. Without an additional device, the maximum
power that PoWeRdRIVe md2cs can absorb is limited to its
internal losses. If the application generates significant braking
power (inertia slowdown, braking, etc) a device should be
added to the standard product consisting in a braking module
(md2tF400 or md2tHF330) and an external RF-md resistor.
5.6.1 - Braking modules
md2tF transistors consist of an IGBt transistor and a control
circuit.

• Connexions
• connect the braking resistor to the transistor md2tF400
• Connect a thermal relay Rth (not fitted), set to the stated
current for the resistor associated with it.
• connect the P14 map to the associted connector on the
interface board of the drive (tilt the control board to access the
interface board).
• connect dc+ et dc- to the drive dc bus bars with
connection clamps (ie Rittal ref. 3457.500).
