Mounting
location
z The mounting location must comply with the device features mentioned in the chapter
”General data”.
z Flammable materials or substances must not be placed in the vicinity of the brake
resistor.
z The heat generated by the brake resistor must be dissipated freely.

Design and
project planning
z Mean value of regenerative power < permanent power P
d
of brake resistor.
z Regenerative power during braking time < heat quantity Q
B
of brake resistor.
z Braking time < 10 % of cycle time (braking time + dead time).
z Always connect the thermal contact and integrate it in a way into the system monitoring
that the mains supply will be switched off when the basic device is overheated.
