MEP-4xxx Direct-Coupled Actuators (40 to 90 in-lb.) 10 Applications Guide, AN0513A Rev. J
WARNING
Risk of electrical shock in line-voltage models.
Disconnect ALL power before servicing. More
than one disconnect provided on models
with auxiliary switches. Failure to follow
electrical safety precautions with live electrical
components could result in injury or death.
WARNING
If both conduit connections are used in line-
voltage models, they MUST be externally
connected during installation. The nonmetallic
enclosure does not provide grounding
connection between the two conduit
connections.
Wiring Issues
• Check for correct wiring for the application.
• Check the wiring at the connected devices.
• Use a voltmeter and ohmmeter to check the
terminals for expected values.
• See Tips for Connecting 24-Volt Power Applica-
tion Note (AN0604D).
NOTE: Wiring must be adequate to avoid exces-
sive voltage drop on long runs! Allow
plenty of “cushion” in measurements. A
meter may be too slow to register tran-
sient dips or peaks during startup.
Configuration
Proportional (MEP-4xx2) Models Setup
NOTE: Before Jan. 2014, MEP-40x2/48x2
proportional models had 0–10 VDC inputs
and 0–5 or 0–10 VDC feedback (only).
From 2014 through July 2015, they had
2–10 VDC inputs and 1–5 or 2–10 VDC
(only) feedback instead. Starting in August
2015, all these options were available and
selectable via a jumper and slide switch.
NOTE: Before August 2015, the MEP-
42xx/45xx/49xx fail-safe proportional
models had 2–10 VDC inputs and 1–5 or
2–10 VDC feedback (only). Starting in
August 2015, 0–10 VDC inputs and 0–5 or
0–10 VDC feedback were also available and
switch-selectable.
NOTE: When the 0–10 VDC input is selected,
selectable feedback options are 0–5 or 0–10
VDC. When the 2–10 VDC input is selected,
feedback options are 1–5 or 2–10 VDC.

tomapping, see the relevant installation guide:
