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:
72/23EECEC Low Voltage Directive
89/336 EECEC 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).
How to assemble (see Fig. 6.1)
