User manual of EC160 elevator intelligent integrated machine Installation and wiring
26
no more than 4Ω. Do not use the special grounding wires with other
devices.
Do not short circuit or ground the input/output circuits.
The output terminal U/V/W of the machine needs to go through the
ground metal pipe and route separately with the signal wires of the
control circuit to avoid interference.
4.2.5 Connection of braking circuit of intelligent integrated machine in main circuit
The machine is embedded with braking unit. In order to release the regenerative energy, it is
necessary to connect braking resistor in the terminal of (+) and PB.
The temperature of the braking resistor will increase as the heat-releasing. Ensure safety
protection and good ventilation when installing braking resistor.
Figure 4-5 Connection diagram of braking resistor and braking unit
(+) and (-) cannot be connected with the braking resistor directly,
otherwise damage to the machine or fire may occur.
4.2.6 Connection of RBU series energy feedback unit
RBU series energy feedback unit can feedback the power generated from the motor to the grid.
The connection is shown as below:
