Note that the value for the rms power depends on the following conditions:
Resistor installed vertically with the connection cables at the bottom and
separated from the nearest surface at a distance of at least 10 cm (about 4
inches).
WARNING. Careful with the surface of these resistors. Remember that its
temperature may reach 410 °C (770 °F).
Chapter 6. POWER LINE CONNECTION shows the installation rules for
external braking resistors that must be followed strictly in order to install
them properly. Chapter 11. DIMENSIONS of this manual shows their dimensions.
