NOTICE
Material damage when exceeding the maximum permitted cable length
Exceeding the maximum permitted cable length to the braking resistor can cause property
damage due to component failure.
• Comply with the maximum cable length between the cabinet unit and the braking

Max. connectable cross-section: 2/0 (70 mm²)
Recommended conductor cross-sections:
● For L61 / L64 (25 kW): #1 AWG (35 mm²)
● For L62 / L65 (50 kW): 1/0 (50 mm²)

Fire when the thermostatic switch is not evaluated
If the thermostatic switch is not evaluated, then there is the danger of fire damage with
death or severe injury.
• Evaluate the thermostatic switch using the Control Unit or a higher-level control system;
