Notes：
 Different models may have some changes, please in kind prevail!
 Inverter terminals (P+ , P-) shall be in accordance with braking unit terminal symbol during
wiring, damage will caused if wrongly connected.
 The wire distance between braking unit and braking resistor unit shall be kept within 5
meters, or within 10 meters if using twisted pair.
 If the transistor in braking unit is damaged (short circuit), resistor will be very hot which is
easy to cause fire. Therefore, installing electromagnetic contactor on inverter input terminal
is recommended because it allows cutting off power when fault occurs.
 Cable must be of 75° C copper.
 Screw with proper strength. Loose screwing will lead to short circuit or wrong
operation, while over-tight screwing will result in damages to screws and terminals, and
short circuit or wrong operation too.
