4.1.5 Regeneration Resistor Wiring
The regeneration resistor can be installed by the user (see chapter 4.3). If during normal operation fault "1"
occurs (overvoltage; see chapter 6), a regeneration resistor must be connected to the controller to over-
come this problem. For regeneration resistor installation the recommendations below should be observed.

1): Duty cycle = 2% at T = 120s
The generation resistor is not automatically included in the
delivery.
The generation resistor must be mounted horizontal on a
vertical surface for full power rating.
For vertical mounting on a horizontal surface the nominal load
capacity is reduced to 65%.
Take care of good cooling of the regeneration resistor.
The ambient temperature of the resistor can be up to 200°C, in
a distance of 30mm.
Keep a safe distance between regeneration resistor and
flammable materials. The mounting surface can reach a
temperature of 80°C.
Wiring:
The resistor must be wired with a 2 lead (2,5 mm
2
) screened cable. The resistor housing must be grounded.
