MEP-42xx/45xx/49xx Options
Tri-State/2-Position Rotation Direction
Tri-state/two-position MEP-4xx1/4xx3 models (ex-
cept MEP-4003) have switches for selecting rotation
direction. Be sure switches are set correctly for the
application.
• Non-fail-safe MEP-4xx1/4x13 models (beginning
in Jan. 2014) have a slide switch to the right
of the terminal block. See the MEP-4000/4800
Series Installation Guide for more information.
Two-Position Wiring (MEP-4001/3/4/5)
MEP-4xx4/4xx5 two-position actuators have “tradi-
tional” two wires for 24 VAC/VDC or 100–250 VAC
signal/power.
• Fail-safe MEP-4x51 and fast-acting MEP-4x01
models have selector switches to the left of the
terminal block. See the MEP-4200/4500/4900 Se-
ries Installation Guide or MEP-4201/4501/4901
Installation Guide for more information.

Starting in January 2014, tri-state MEP-4xx1/4xx3
models (except MEP-4003) also oer two-position
functionality as an option. That option is dependent
on wiring conguration and selector switch position.
See Tri-State/2-Position Rotation Direction on page
11. The (tri-state) two-position option requires
“three-wire” (non-fail-safe) or “four-wire” (fail-safe)
wiring conguration.
