Guidelines for the safety of the user and protection of the FX2NC.
This manual provides information for the installation and use of the FX2NC. The manual has
been written to be used by trained and competent personnel. The definition of such a person
or persons is as follows;
a) Any engineer who is responsible for the planning, design and construction of automatic
equipment using the product associated with this manual should be of a competent
nature, (trained and qualified to the local and national standards required to fulfill that
role). These engineers should be fully aware of all aspects of safety with regards to auto-
mated equipment.
b) Any commissioning or service engineer must be of a competent nature, trained and qual-
ified to the local and national standards required to fulfill that job. These engineers
should also be trained in the use and maintenance of the completed product. This
includes being completely familiar with all associated documentation for the said product.
All maintenance should be carried out in accordance with established safety practices.
c) All operators of the completed product should be trained to use that product in a safe and
co-ordinated manner in compliance to established safety practices. The operators should
also be familiar with documentation which is connected with the actual operation of the
