Installation locations Indoor
Outdoor (keep away from direct sunlight.)
Installation orientation Installable in any position ranging from upright to sideways.
(If being installed outdoors, it must be installed in upright position.)
Valve position indication Pointer located at the bottom of the actuator shows the position by pointing at the value of the
scale (0: close to 100: open) on front, rear, and bottom sides.
Manual operation Discconect from the power supply. Using a wrench, rotate the rectangular part (joint) at the
connection between the valve and the actuator.
Refer to the section “Manually Opening/Closing Valve.”
Wiring Two knockout holes (
φ
22 mm, for wiring port) are located on bilateral sides. Cut out the required
one and connect the wiring to the terminal block with screws (M3.5).
