Connection diagram of Brake unit and Inverter
*NOTE
:
(1)
Cable length of the frequency converter and braking unit is less than
5 m
(2)
Cable length of the Braking resistor (Rb) and brake unit is less than
10 m, and must use heat-resisting conductors
(3)
P, N is the terminal "+""-" of the frequency inverter dc bus, P is the
positive terminal, e, N is a negative terminal "-"
(4)
P, N line must be twisted together, Rb and Rb ' line must be twisted
together..
!
Warning
:
Incorrect connection of the main circuit will lead the
damage to the brake unit and inverter.
