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 AC rating: 24V AC±10%, 47 – 66 Hz, approx. 25VA (MSP6)
24V DC: 24V rating ±10%, approx. 0.6A
• Built-in power fuse: 250V/1A rating; time delay.
• A rush current 1.5 times as high as the above ratings can
flow at startup.
■ GENERAL PRECAUTIONS
• Remove the power supply to the actuator before wiring.

MODEL
■ 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: 2 G (19.6 m/s ) max.
2
• Install the MSP where it can be reached for maintenance
and inspection. Be sure to allow at least 15 cm (6 inches)
clearance above the cover.
■ 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 give some slack to the cable.
• Do not mount the MSP in such a direction that the output
stem or cable connector faces upward.
Cable Connector
■ ELECTRICAL CONNECTION
• If the unit is a DC-powered model, power supply and sig-
nal lines are not isolated. Use an isolator, if needed.
• When wiring the unit using a cable longer than the
standard 1-meter cable equipped to the non-terminal box
model, use shielded cables for signal line, or install signal
cables in a separate duct/pipe from power supply cables.
■ LIGHTNING SURGE PROTECTION
• In order to protect the unit from lightning surges enter-
ing through cables, use of appropriate lightning surge
protectors are recommended. For 24V DC power supply
line, choose a surge protector with its maximum surge
voltage 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 control shortens the life of
actuator and valve.
■ O-RING, PACKING
• 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
packing is properly applied.
DO NOT Pull Tightly
