1.3 Notes on possible property damage

NOTICE
!
Risk of damage to the electrohydraulic actuator due to the supply voltage exceeding
the permissible tolerances.
The Type 3274 Electrohydraulic Actuator is designed for use according to regulations
for low-voltage installations.
Î Observe the permissible tolerances of the supply voltage.
Risk of electrohydraulic actuator damage due to excessively high tightening torques.
Observe the specified torques when tightening the mounting parts of Type 3274 Electro-
hydraulic Actuators. Excessive tightening torques lead to parts wearing out more quick-
ly.
Î Observe the specified tightening torques.
Risk of damage to the electrohydraulic actuator due to incorrect operation of the me-
chanical override.
The actuator stem of the electrohydraulic actuator can be moved manually in the version
with mechanical override.
Î Do not operate the manual override while the actuator is in operation or while the
voltage supply is still connected.
Unauthorized activation of the electric override will affect the control process while
the process is running.
The actuator stem of the electrohydraulic actuator can be moved manually in the version
with electric override.
Î Only activate the manual override after consulting the plant operator.
Î Isolate the valve, if necessary.
Risk of damage to the electrohydraulic actuator due to unauthorized opening of the
top housing cover.
Do not open the top housing cover. It is part of the pressure-tight actuator housing,
which also serves as the oil reservoir. Once the cover has been opened, the proper
functioning of the electrohydraulic actuator is no longer guaranteed.
Î Do not open the top housing cover.
