Housing temperature may reach 200°C.

Dangerous voltage!

The device may only be used if completely fitted!

The external ballast resistances should be fitted so that contact protection is provided.

The housing temperature of the ballast resistance may rise to 200°C depending on the application.

Fit the connection lines underneath.

Observe the information on the resistances (warning signs).

Braking time / s

Example 1: For a braking time of 0.8s, a braking power of 700W is required. The following can be determined from the diagram:

At the required magnitudes, this is between factor F=2 and factor F=5.

To maintain operating safety, select factor F=5; therefore the required cooling down time equals:

Cooling down time = F * braking time = 5 * 0.8s = 4s

Example 2: For a braking time of 0.3s, a braking power of 1000W is required. The following can be determined from the diagram:

At the required magnitudes, this is between factor F=2 and factor F=5.

To maintain operating safety, select factor F=5; therefore the required cooling down time equals:

Cooling down time = F * braking time = 5 * 0.3s = 1.5s
