AEL7 Series Electric actuator
Before considering installation of an AEL7 Series actuator please read to Section 1 "Safety
Information" on page 4.
-
Installation awareness
-
Lifting and fitting of actuators increases the risk of personal injury
-
Mains connection and commissioning of the AEL7 Series actuator requires specialist
knowledge of electrical circuits and systems, and the inherent dangers. A working
knowledge of linear actuators is also required.
-
Risk of injury by moving parts. Ensure that that the control system is disabled and the
electrical power supply is isolated to ensure that the valve and actuator do not move
without warning.
-
The incorrect use of power supplies to assist the installation, commissioning and
maintenance of electrically actuated valve assemblies increases the risk of personal
injury.
-
Lifting and fitting or actuators increases the risk of personal injury
-
Crush hazard
When actuators are to be fitted using lifting equipment always ensure that the actuator
is carefully slung in order that it cannot fall. Never attempt to remove a control valve
from the line by using the actuator as the lifting point. The actuator or the lifting
equipment could become damaged.
Never stand under components that are being lifted. Head safety protection must always
be worn when operating on or close to equipment where lifting operations are taking
place.
Do not place hands within the actuator yoke or on the stem when isolation of the
electrical power supply has been removed.
Do not attempt to restrict actuator stroke or movement, or increase seat load through
the placing of objects within the actuator yoke. This practice could also result in the
loss of sight.

Warning
Muscular skeletal damage
For small actuators that do not require mechanical lifting aids, always ensure that
manual lifting best practice is observed. Always use two personnel where possible and
ensure that proper access is available in order to ensure a secure foothold.
3.1 Location
The actuator should be mounted above the valve and provide sufficient space to remove the cover and
provide general ease of access. When selecting the location, make sure that the actuator is not exposed to
an ambient temperature exceeding the range -20 °C to + 60 °C (-20 °C to +50 °C for actuators fitted with
positioners). All actuators except AEL71 is IP54, but only when the lid is correctly fitted (see Section 3.3).
Adequate shelter and an anti-condensation heater must be provided for outdoor installations. For internal
installations where there is a risk of condensation an anti-condensation heater should also be installed.
