Important
If plug 1 is used to power the device a tape wound core (toroidal core) is nec-
cessary to suppresse high frequencies in order to ensure compliance with
FCC regulations
NOTE
Torque transducers are only intended for operation with a DC supply voltage
(separated extra-low voltage), see page 43.
