The inverters above 37kW (including 370kW) only needs external 
braking units. 
 (+), (-) are the wiring terminals of the braking units. 
 The wiring length between the (+),(-) terminals of the inverter and the 
(+),(-) terminals of the braking units should be no more than 5m,and the 
distributing length among BR1 and BR2 and the braking resistor 
terminals should be no more than 10m.
