*3 The peripheral braid sleeve of the pressure sensors needs to shield completely the internal signal wires.
Make the signal wires which are not shielded by the braid sleeve as short as possible. Also bring signal
wires as close to the control terminals as possible. Connect the peripheral braid sleeve to PE grounding
terminal. If the impulse noise or any other noise is too strong, connect the signal wire to the ACM terminal
to eliminate noise.
