8.8 Braking resistors
The supply cables to the braking resistors carry a high pulsed DC voltage during nom-
inal operation.
DANGER
Dangerous pulsed DC voltage of up to 970V.
Severe or fatal injuries from electric shock.
To prevent electric shocks:
• Disconnect the application inverter from the power supply and wait 10 minutes
before working on a braking resistor or its supply cables.
• Never operate the application inverter without touch guards and installed closing
covers.
Braking resistors get very hot during operation.
WARNING
The surfaces of the braking resistors will reach temperatures of up to 250°C when
the braking resistors are loaded with the nominal power.
Severe burns.
To prevent burns:
• Do not touch any hot braking resistor.
• Select a suitable installation location for the braking resistors such as the control
cabinet roof.
