2. POINTS OF CAUTION
■
POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
24V DC: 24V rating ±10%, approx. 0.5A
■
GENERAL PRECAUTIONS
• Remove the power supply to the actuator before wiring
to it.
■
INSTALLATION
• Indoor, or outdoor where the MSPxC is NOT exposed to
direct 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
) max.
• Install the MSPxC where you can reach for maintenance.
Observe at the minimum of 15 centimeters (6 inches)
above the cover.
■
ELECTRICAL CONNECTION
• Separate the cables (power supply and communications)
from other cables to prevent surge or inductive interfer-
ence.
• Do not bind these cables together with mains supply ca-
bles or high-voltage cables. Do not install them in the
same duct.
■
OUTDOOR USE
• When installing the MSPxC outdoor or where it is ex-
posed to rain or water drops, be sure to fasten the cable
connector tightly and leave a slack of the cable.
• Do not mount the MSPxC in such direction that the out-
put stem is at the top of the Mini-Top unit.
■
O-RING, GASKET
• When replacing the actuator cover after adjustments,
check that the O-ring is securely placed in the groove.
• When replacing the communication box cover, check that
the gasket is in place.
■
YOKE DESIGN
• When a foreign object is caught in the valve, a torque four
times greater than the maximum rating could be gener-
ated. Leave enough strength for mechanical components
such like the yoke and stem.
• If the MSPxC is used on a steam line in temperature
control, it is possible that the MSPxC temperature rises
higher than the ambient temperature due to transmis-
sion or radiation via the steam piping, even when the am-
bient 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.
