POINTS OF CAUTION
■ CONFORMITY WITH EU DIRECTIVES
• This equipment is suitable for Pollution Degree 2 and
Measurement Category II (Full-open/-closed signal, tran-
sient voltage 1500V). Reinforced insulation (Full-open/-
closed signal to other, power or metallic housing: 125V) is
maintained. Prior to installation, check that the insula-
tion class of this unit satisfies the system requirements.
• Altitude up to 2000 meters.
• The equipment must be installed such that appropriate
clearance and creepage distances are maintained to con-
form to CE requirements. Failure to observe these re-
quirements may invalidate the CE conformance.
• Install lightning surge protectors for those wires connect-
ed to remote location. Refer to "LIGHTNING SURGE
PROTECTION" section below.
■ POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
100 – 120V AC rating: 90 – 132V, 47 – 66 Hz, approx. 25VA
200 – 240V AC rating: 180 – 264V, 47 – 66 Hz, approx. 25VA
24V DC: 24V rating ±10%, approx. 0.6A
• A fuse of the following rating is incorporated: 250V/1A
time delay.
• A rush current 1.5 times as high as the above ratings can
flow at the startup.
■ GENERAL PRECAUTIONS
• Remove the power supply to the actuator before wiring to it.
■ INSTALLATION
• Indoor, or outdoor where the MSP is NOT exposed to di-
rect sunlight
• Ambient temperature: -5 to +55°C (23 to 131°F)
• Operating humidity 30 to 85% RH (non-condensing)
• Vibration: 0.5 G (4.9 m/s
2
• Install the MSP where you can reach for maintenance.
Observe at the minimum of 15 centimeters (6 inches)
above the cover.

MODEL
■ OUTDOOR USE
• When installing the MSP outdoor or where it is exposed
to rain or water drops, be sure to fasten the cable connec-
tor tightly and leave a slack of the cable.
• Do not mount the MSP in such direction that the output
stem or cable connector is at the top of the MSP unit.
Cable Connector
■ ELECTRICAL CONNECTION
• With DC power type unit, power supply and signal lines
are not isolated. Use an isolator if needed.
• When you use a cable other than the standard 1-meter
cable equipped with non-terminal box type unit and its
extension distance is longer than that, use shielded ca-
bles for signal line, or install signal cables in a separate
piping from power supply cables.
■ LIGHTNING SURGE PROTECTION
• In order to protect the unit from lightning surges entering
through cables, use of appropriate lightning surge protec-
tors are recommended. For 24V DC power supply line,
choose a surge protector with its maximum surge volt-
age 40V or less between lines. Recommended M-System
model: MDP-D24.
■ PID CONTROLLER
• Choose PID parameters carefully so that the MV remains
as stable as possible. Unstable operations shorten the life
of actuator and valve.
■ O-RING, GASKET
• When replacing the actuator cover after adjustments,
check that the O-ring is securely placed in the groove.
• When replacing the terminal box cover, check that the
gasket is in place.
■ YOKE DESIGN
• When a foreign object is caught in the valve, a thrust 2
times greater than the maximum rating could be gener-
ated. Leave enough strength for mechanical components
such like the yoke and stem.
• If the MSP is used on a steam line in temperature con-
trol, it is possible that the MSP's temperature rises high-
er than the ambient temperature due to transmission or
radiation via the steam piping, even when the ambient
temperature is within allowable range.
Use a longer yoke to increase heat dissipation and apply
insulating material.
■ AND ....
• DO NOT loosen the screw fixing the potentiometer stem.
Loosening it could cause a malfunction.
• DO NOT step onto the actuator. DO NOT rest a heavy
object on or against it.
