6 Mechanical installation

6.1 Important notes

ƒ Only use the braking units as built−in units!

ƒ Observe mounting clearances!

– Observe clearance of 100 mm at the top and at the bottom.

ƒ Make sure that the cooling air can access and the exhaust air can escape

unimpededly.

ƒ If the cooling air is polluted (dust, lints, greases, aggressive gases), which

may affect the function of the braking units:

– Take adequate countermeasures, e. g. separate air guide, installation of

filter, regular cleaning, etc.

ƒ Do not exceed the permissible range of the ambient operating

temperature (see chapter 4.1).

ƒ If the braking units are permanently exposed to vibrations or shocks:

– Check the use of vibration dampers.

Possible mounting positions

ƒ Vertically on the rear panel of the control cabinet, power connections

facing upwards

– Fixed with enclosed fixing rails (see chapter 6.2)

– Thermally separated with an external heatsink ("Push−through

technique") (see chapter 6.3)

– Thermally separated with an external convection cooler ("Cold plate"

technology) (see chapter 6.4)

 Danger!

ƒ In case of fault, brake resistors can reach very high temperatures;

the brake resistor may even burn down, e. g. in the case of

– mains overvoltage,

– application−specific overload,

– internal error.

ƒ Therefore mount the brake resistors so that no damage can be

caused by the possible, very high temperatures.
