INSTALLATION
2.0 Installation
2.1 Electrical Considerations
2.1.1 Any electrical connections required are the responsibility of the user. Connection documentation is supplied with the actuator.
Refer to the applicable wiring diagram to identify functions of terminals. Verify that the electrical supply characteristics are
compatible with the supplied actuator control components.
2.1.2 Only appropriate certified explosion-proof entry reducers, glands or conduit may be used if the unit is installed in a hazardous
area. Remove any plastic transit plugs. Make cable entries appropriate to the cable type and size. Ensure that threaded
adaptors, cable glands or conduit are tight and fully waterproof. Seal unused cable entries with a steel or brass plug. In
hazardous areas an appropriately certified threaded blanking plug must be used.
2.1.3 Access to live electrical conductors is forbidden in hazardous areas unless done under a special permit to work. Otherwise, all
power should be isolated and the unit moved to a non-hazardous area for repair or attention.
2.1.4 The actuator and control components must be protected from electrical spikes, surges, and lightning strikes as well as
magnetic or electro-magnetic fields. This is the responsibility of the user.
2.2 Motive Power Supply (pneumatic, hydraulic)
2.2.1 Ensure that the actuator will not be exposed to pressure in excess to the maximum rating as indicated on the nameplate.
2.2.2 Verify that medium composition (e.g., filtration, hydration) correspond to that for with the actuator was manufactured.
Rotork Fluid System must be contacted to verify compatibility of any proposed changes to supply medium.
2.2.3 Ensure that throughout the installation that there are no leaks of a potentially explosive supply medium (e.g., natural gas).
Note: Depending upon control circuit design, pneumatically powered actuators may exhaust the power supply gas to
atmosphere in the course of normal operation. This may present an unacceptable hazard in some applications. Consult Rotork
Fluid Systems if in doubt as to the suitability of the equipment supplied for your application.

INTRODUCTION
1.0 Introduction
This manual is produced to enable a competent user to install, operate, adjust, inspect, and maintain Rotork Fluid Systems GP
range actuators. Users are responsible to follow the instructions in this manual as well as any additional documentation that
has been supplied regarding the actuator or accessories supplied by Rotork Fluid Systems. Should further information or
guidance relating to the safe use of GP range actuators be required, it will be provided on request. Users are also responsible to
be familiar with and follow any relevant legislation or statutory provisions regarding health and safety.
It is the users responsibility to ensure that the equipment is operated in a safe manner and that any personnel working with or
on the equipment are properly trained for the work they are performing and are also aware of their responsibilities relating to
health and safety in the workplace. It is extremely important that precautions are taken to avoid spark or static discharge in any
areas of potentially explosive atmosphere.
All Rotork Fluid Systems actuators are tested prior to despatch. Job specific documentation is shipped with the actuator. Test
certificates and replacement documentation are available upon request. The latest general information regarding any Rotork
product is available on our website www.rotork.com.
