current sensors. Magnetic fields in the immediate vicinity can
result in false current measurement results. If possible, lay feed
and return line closely side by side. Do not install devices pro-
ducing magnetic fields in the immediate vicinity of the actuator,
e. g. doorbell transformer, power contactor, etc.
