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.
TheType3374ElectricActuatorisdesignedforuseaccordingtoregulationsfor
low-voltage installations.
Î Observe the permissible tolerances of the supply voltage.
Risk of actuator damage due to excessively high 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 or while the
voltage supply is still connected.
