MDP90A.. without line contactor
NOTICE
Operation without line contactor
If the required measures are not taken, operation of an inverter with connected braking resistor without line contactor may result in severe damage to property.
- For the required measures as well as the inverters that can be operated without a line contactor, refer to chapter "Electrical installation" > Installation instructions > "Using a line contactor".
INFORMATION
In case of a line connection without line contactor, the temperature evaluation of the braking resistor via connection X7 of the power supply module must be ensured. The temperature evaluation is evaluated as error message in each axis.
Refer to the table in chapter Using the line contactor to find out which inverters can be operated without line contactor.
The following figure shows an example of the wiring of the power connections MDP90A.. without line contactor.
[1] | Line fuse |
[2] | Line choke (optional) |
[3] | Line filter |
[4] | Braking resistor (optional) |
[5] | Motor |
