INSTALLATION & USER’S MANUAL
Safeguards should be an integral part of a work cell design, installation, operator training, and operator
procedures. A computer-controlled system may activate remote devices under program control at times not
anticipated by personnel. It is critical that safeguards be in place to prevent personnel from entering the work cell
whenever equipment power is present. Moog highly recommends the use of work cell safety features such as
light curtains, safety gates or safety floor mats to prevent access to the workcell while power is present.
Computer controlled systems have various communication features which may aid the user in constructing
system safeguards, including:
•
emergency stop circuitry
•
binary input and output lines
•
spare system-controlled user lines
The emergency power-off circuitry of a computer-controlled system is generally capable of switching external
power systems, as well as detecting intrusion signals from safety barriers.
All personnel must observe sound safety practices during the operation and testing of all electrically powered
equipment. To avoid injury or damage to equipment, always remove power BEFORE attempting ANY repair or
upgrade activity.
2.2.3
Safety Requirements for Cables
a) Requirements - Conductors and Cables
All cables and conductors used shall be specified as compliant with the requirements of European Standard EN
60204-1 and other known National and International Standards for the environment in which they are installed
and for the voltage and current carried.
Conductors and cables shall be specified and selected so as to be suitable for the operating conditions (e.g.
voltage, current, protection against electric shock, grouping of cables) and external influences (e.g. ambient
temperature, presence of water or corrosive substances, mechanical stress) which can exist.
User's whose machine installations require CE-
Compliance should read this Section.
