1. Use shielded, twisted cable (1) 61m (200 ft) max.
2. Cut and tape back shield wire (2) at sensor (3) end.
3. Connect the other end of shield wire to ground (4) (for example, use a stud in an enclosure).
4-20 mA UI Wiring
The inputs support self-powered 4–20 mA sensors. Input accuracy is ±2% of span, without user calibration. Use a 499 ohm resistor
wired across the input terminals.
NOTE: When using an externally powered 4–20 mA sensor, be sure to de-energize its power supply before making or
changing any wiring connections to the MS-E10 Controller.
This is in addition to removing power from the MS-E10 Controller.
DO NOT apply external power to the UI inputs without the 499 ohm
resistor in place. Otherwise, even a momentary application of power (for example, 24 Vdc) to the UI terminals without the resistor may damage
circuitry on the MS-E10 Controller. Only after completing all input wiring should you restore power to such external power supplies.

Binary Input UI Wiring
The universal inputs support normal dry (equipment status) contacts. Standard dry contacts must have a 1 Hz (or less) COS frequency,
with minimum dwell time > 500 ms (contacts must remain open at least 500 ms and be closed at least 500 ms). Dry contacts support 11
Vdc open circuits or 733 µA short-circuit current.
