instance, after a larger number of parameters has been
changed)

ASSEMBLING AND PUTTING THE ELECTRIC ACTUATOR INTO OPERATION
After receiving the actuators from the manufacturer, the customer should check whether they have not been damaged
during transportation. Check should be made whether data on the plates of the actuator agree with the order and with
the accompanying documentation. Possible discrepancies, defects and damages should be immediately reported to the
supplier. In this case, the actuator cannot be put into operation. If the unpacked actuator is not mounted immediately,
it should be stored in a dust-free room with temperature ranging between -25 °C and +50 °C and relative humidity up to
80 %; the room should be free of caustic gases and vapours and protected against harmful climatic effects. Any manipulation
at temperatures below -25 °C is prohibited. The actuators must not be stored in the open area or in rooms not
protected against rain, snow and frost. Surplus conserving grease should be removed just before putting the actuator into
operation. When unpacked actuators are to be stored for a period longer than 3 months, it is recommended to insert
a sachet with silicagel or another suitable desiccant under the actuator cover.
The user can only put into operation the electric devices in satisfactory conditions documented by a report on initial
revision. Before fitting, the actuator should be carefully inspected, particularly in case it has been stored for a longer time;
the following check should be made:
– conditions of parts and connections forming explosion-proof closure,
– insulation resistance of motor winding,
– absence of any damage to the actuator during storage.
It should again be verified whether placement corresponds to provisions of the paragraph “Working conditions”.
If different way of assembly is necessary due to local conditions, an agreement with the manufacturer is required.
The protective conductor must be connected to the protection terminal marked according to ČSN IEC 417. The actuator
is fitted with protection terminals on the frame and inside the actuator on the control panel at the terminal board.
Connection
The actuator is connected according to the wiring diagram located inside the cover in such a way that the mains supply
wires have permanent good contact with the connecting terminals. The mains voltage should correspond to
the voltage specified on the rating plate of the actuator. The Internal space of the cover must be clean and dry. There must
not be any freely protruding wires on the connected cables.
