1) Please consider the cable resistance if you use longer connection cables. The cable resistance must
be added to the brake resistance and has therefore a considerable influence on the total
resistance.
2) Device consists of master and slave connected in parallel. Usually, the brake energy is dissipated
evenly via master and slave.
3) Please see the switch−on cycle of the brake resistor used.
