Environmental
Actuators must be suitable for indoor and outdcoor use with a standard corrosivity category, C4 medium durability as per ISO 12944. The actualtor must be capable of functioning in an ambient temperature ranging from-30ºC(-22°F)to +70°C(+158°F),up to 100% relative humidity. Actua-tors for hazardous area applications must meet the area classification, gas group and surface temperature requirements specified in the data sheet.
Enclosure
Actuators shall be O-ring sealed, watertight to IP66/IP68 20m for 10 days, NEMA 4, 6. The motor and all other internal electrical elements of the actuator must be protected from ingress of mois-ture and dust when the terminal cover is remolved for site cabling. The terminal compartment must maintain the same ingress protection rating with the terminal cover removed. The actuator enclosure must allow for temporary site storagewithout the need for electrical supply connection. All external fasteners shall be suitable for the actuator corrosivity category and installation envi-ronment indicated on the datasheet.
