Mounting location
l
In the control cabinet
l
The mounting location must comply
with the device features mentioned in
the chapter "General data".
l
Flammable materials or substances
must not be placed in the vicinity of the
brake resistor.
l
The heat generated by the brake resistor
must be dissipated freely.
Mounting position
Vertically suspended with connecting cables
at the bottom.

of brake resistor.
l
Regenerative power during braking time
< thermal capacity C
B
of brake resistor.
l
Braking time < 10 % of cycle time
(braking time + dead time).
l
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.
