1. APPLICATION
The electric actuators
MODACT MONED, MOPED, MONEDJ are designed for shifting valves and/or other
elements for which they are suitable with their reversible rotary motion. Other using than that for controlling valves
should be discussed with the manufacturer. The actuators can operate in circuits of remote control. The actuators
can also operate in circuits of automatic regulation with the regime S 4 - 25 %; 1200 h

2. OPERATING CONDITIONS, OPERATING POSITION
Operating conditions
The actuators
MODACT MONED, MOPED, MONEDJ are resistant against influence of operating conditions and external
effects of the classes AC1, AD5, AD7, AE4, AE6, AF2, AG2, AH2, AK2, AL2, AM-2-2, AN2, AP3, BA4 a BC3 according to
ČSN 33 2000-5-51 ed. 3.
When the actuator is installed on a free area it is recommended to fit it with a light shelter against direct impact of
atmospheric effects. The shelter should overlap the actuator contour by at least 10 cm at the height of 20 – 30 cm.
The electric actuators can be installed in areas with non-flammable and non-conductive dust, provided that this
does not adversely influence their function. Here, it is necessary to strictly observe ČSN 34 3205. It is recommended
to remove dust as soon as its layer is about 1 mm thick.
Notes:
The area under a shelter means the one where falling of atmospheric precipitations under an angle up to 60° from the vertical is
prevented.
The electric actuator must be installed in a place where cooling air has a free access. Minimum distance from a wall for access of
air is 40 mm. Therefore, the area where the electric actuator is installed must be sufficiently large, clean and ventilated.
