Thermal protection of the resistors
The standard resistors available as D151 are equipped with a thermal switch. The
switches of the resistors are wired in series and connected to the Enable input of the brake
chopper. The relay output of the chopper is wired to the supply control unit so that a chopper
fault condition stops the supply unit.
With custom resistors, user must implement a similar protection. Use cable rated as follows:
•
twisted pair, shielding recommended
•
rated operating voltage between a conductor and ground (
U
0
) > 750 V
•
insulation test voltage > 2.5 kV.
Keep the cable as short as possible.
■
Protecting the resistor cable against short-circuits
The input fuses of the drive will also protect the resistor cable provided that the resistor
cable is of the same type as the input cable.
Mechanical installation of custom brake resistors
Obey the resistor manufacturer’s instructions.

Connection procedure
WARNING!
Obey the instructions in chapter Safety instructions. If you ignore them,
injury or death, or damage to the equipment can occur.
•
Do the steps in section Electrical safety precautions in chapter Safety instructions before
you start the work.
•
Connect the resistor cable at the resistor end only. If a shielded three-conductor cable
is used, cut off the third conductor. Ground the twisted shield of the cable as well as
any separate PE conductor (if present).
