The limit values for emitted interference according to the applicable device standards do not rule out the possibility that receivers and susceptible
electronic devices within a radius of 10m are subjected to interference. If such interference, which is definitely attributable to the operation of the
braking devices "VB", occurs, the emitted interference can be reduced by taking appropriate measures.
Such measures are, e.g.:
To connect reactors (3mH) or a suitable mains filter in series before the braki
ng
device, or to connect X-capacitors (0.15μF) in parallel to the
supply voltage terminals.
EMC
Really ensure correct terminal-phase connections
between input of braking device (L1,L2) and output
of braking device (T1,T2).
