2. EC Manufacturer‘s Declaration
The manufacturer, Georg Fischer Piping Systems Ltd, CH-8201 Schaffhausen, declares that the electrical actuator EA 11 is not a ready-to-use
machine in the sense of the EC Machine Directive and cannot therefore meet all the requirements of this directive.
60
¥ ‡
Operation of these actuators is prohibited until conformity of the entire system into which the valve and the actuator have been installed is established according to the EC Directives listed below.
Applicable EC Directives:
72/23 EEC EC Low Voltage Directive 89/336 EEC EC Directive on Electromagnetic
Compatibility
Modifications to the actuator which have an effect on the technical data given in this instruc­tion manual and its intended use, i.e. signi­ficantly alter the actuator, render this manufacturer‘s declaration null and void.
3. Intended Use
Warning
When mounted on a valve and connected to a system control, the purpose of this actuator is to ł actuate valves with 90° pivoting (ball valves and
butterfly valves),
ł indicate the previously calibrated end positions
of the valve via electrical signal to the system control (accessory), and
ł provided that the actuator data corresponds to
the electrical control and the valve and
ł in case of interruption in the supply voltage,
warrant that the actuator/valve remains in the current position. Please use emergency manual
override or install fail-safe return. The actuator is not intended for uses other than those listed here. If the instructions contained in this manual are not observed, the manufacturer is excluded from all liability for the above mentioned products.

4. Safety Tips
4.1 Due care required of the operator
The actuator described herein was designed and manufactured with consideration to the respective harmonized European standards. It corresponds to the latest technology and the technical specifica­tions contained under Section 8.
Safety on the job can, however, only be realized if the operator warrants that ł the actuator is only used as indicated under
Section 3,
ł he is familiar with this instruction manual and the
manual of the corresponding valve and adheres to the instructions contained therein and
ł he has taken the necessary measures against
electrostatic influence.
4.2 Special hazards
62
Warning
Under normal conditions, the actuator may only be operated with the cover closed. If work is performed on the actuator with the cover removed, the supply and control voltage must first be disconnected. Adjustments, which need to be done in the energized state, should be carried out with special insulated tools.
In addition, the operating instructions of the manual valve must be observed. They are an integral component of this manual.
¥ ‡
4.3 Transport and storage
The actuators must be handled, transported and stored with care. Please note the following points:
ł The actuators should be transported and/or
stored in their original unopened packaging. ł The actuators must be protected from harmful
physical influences such as dust, heat (humidity). ł It is important that the connections are neither
damaged by mechanical nor thermal influences. ł Prior to installation, the actuators should be in-
spected for transport damages. Damaged actu-
ators must not be installed.

5. Actuator Design
The standard version of the EA 11 electrical actuator consists of the following elements: gear unit, direct current motor, electrical board, and components for end position limiting.
For special applications, the actuator can be equipped additionally with various supplementary kits (see Section 9).

Installation note
If the actuator is connected direct to the power-supply, it is necessary to install a switch-disconnector between the actuator and the power­supply (do not disconnect the earthcable). To avoid water flowing into the actuator it is necessary that the cable insertion ist not upturned.

6. Valve Design
The EA ¢1 electrical actuator can be mounted on ball valves type 546, DN10–50, by using the cor­rect coupling piece and selecting a suitable adap­ter plate with clamps. The actuators are supplied ex works in the «open» position. See Section 6.¢ for the individual assembly components required for the ball valve type ¢07. Both end positions in the actuator have been preset in the factory. It is necessary to readjust these after installation at the customer (see Section 7).
