1.3 Notes on possible property damage
NOTICE
!
Risk of damage to the electric actuator due to the supply voltage exceeding the per-
missible tolerances.
TheType3374ElectricActuatorisdesignedforuseaccordingtoregulationsfor
low-voltage installations.
Î Observe the permissible tolerances of the supply voltage.
Risk of actuator damage due to excessively high tightening torques.
ObservethespeciedtorqueswhentighteningthemountingpartsofType3374Electric
Actuators. Excessive tightening torques lead to parts wearing out more quickly.
Î Observethespeciedtighteningtorques.
Risk of damage to the electric actuator due to incorrect operation of the manual over-
ride.
The actuator stem of the electric actuator can be adjusted manually.
Î Do not operate the manual override while the actuator is in operation. Only operate
themanualoverrideofactuatorswithoutfail-safeactioninthede-energizedstate.
Risk of damage to the electric actuator due to incorrect connection of the voltage.
The electric actuator has terminals to retract the stem (eL terminal) and to extend the
stem (aL terminal).
Î Do not apply a voltage to eL and aL at the same time.
