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
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
for more information.

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