Important notes

Only use the braking units as built−in units!
ƒ
Observe mounting clearances!
ƒ
–
Observe clearance of 100 mm at the top and at the bottom.
Make sure that the cooling air can access and the exhaust air can escape
ƒ
unimpededly.
If the cooling air is polluted (dust, lints, greases, aggressive gases), which
ƒ
may affect the function of the braking units:
–
Take adequate countermeasures, e. g. separate air guide, installation of
filter, regular cleaning, etc.
Do not exceed the permissible range of the ambient operating
ƒ
temperature (see chapter 4.1).
If the braking units are permanently exposed to vibrations or shocks:
ƒ
–
Check the use of vibration dampers.
}
Danger!
ƒ
ƒ
Possible mounting positions
Vertically on the rear panel of the control cabinet, power connections
ƒ
facing upwards
–
Fixed with enclosed fixing rails (see chapter 5.2)
–
Thermally separated with an external heatsink ("Push−through
technique") (see chapter 5.3)
–
Thermally separated with an external convection cooler ("Cold plate"
technology) (see chapter 5.4)

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.
Therefore mount the brake resistors so that no damage can be
caused by the possible, very high temperatures.
