1.6 Operation conditions
1.6.1 Product location and operation position
•
Electric actuators may be installed and operated in enclosed locations of industrial facilities with no
temperature and moisture regulation, protected from direct climatic effects (such as direct sunlight).
Moreover, special “marine” versions may be used in waste water treatment applications, water
management, selected chemical applications, tropical environments and coastal areas.
•
Electric actuators must be placed with access to the manual control wheel (4) (Fig.1), to the cover of control
box (6), to control box (M4), to bushings (7).
•
Installation and operation of actuators is possible in either position, while motor axis is in horizontal position;
variance of motor axis from horizontal plane can be
±
15° . Common position is the one with vertical position
of exit part axis and control box above.
Warning:
When the EA is installed in open air, it must be sheltered lightly to protect is against direct effects of
atmosphere.
When installed in the areas with relative humidity more than 80%, in open air under a shelter is
needed to connect the space heater directly – without a thermal switch.
1.6.2 Operation environment
According to standard IEC 60 721-2-1:
EA have to resist external effects and operate reliably:
in climatic conditions for the group / type of climate:
- version „standard“ - for climate group Restricted (R) + /Warm temperature (WT), Warm Dry (WDr),
Mild Warm Dry (MWDr) and Extremely Warm Dry (EWDr) with corrosion
resistance C3 resp. C4 (EN ISO 12944-2), with temperatures -25
°
C to +55
°
C
- version „cold“ - for climate group Moderate (M) / Cold Temperate (CT), Warm
Temperate (WT), Warm Dry Temperate (WDr) and Mild Warm Dry (MWDr) with
corrosion resistance C3 (EN ISO 12944-2), with temperatures -40
°
C to +40
°
C
- version „marine“ - for climate group World-Wide (WW) / all climate groups except Extremely cold
(EC) and Antarctica inland with corrosion resistance C4 (EN ISO 12944-2), with
temperatures -40
°
C to +40
°
C
Besides this according to GOST 15 150- 69:
- version „tropical“ meet with Dry and Damp tropics , for climate types Warm Temperate (WT),
Warm Dry (WDr), Mild Warm Dry (MWDr), Extremely Warm Dry (EWDr), Warm
Damp (WDa) and Warm Damp Equable (WDaE) with corrosion resistance C3
(EN ISO 12944-2), with temperatures -25
°
C to +55
°
C
CATEGORY OF LOCATION
- versions “standard“ , “cold” and "tropical" are intended for location under the shelter (category 2)
-
version “marine“ is intended for location on the open space (category 1)
ATMOSPHERE TYPE
- versions “standard“ , “cold” and “tropical” are intended for location in atmosphere t ype II industrial
- version “marine“ is intended for location in atmosphere type III sea , type IV seaindustria
(In accordance with IEC 60 364-3:1993)
