INSTALLATION
4.1 General Warnings
These instructions have been designed to assist users of the EFL Relay with installation.
Before the EFL Relay can be installed, there are a number of things that need to be considered and
understood to prevent incorrect or unsafe operation of the EFL Relay or the system into which it is
installed.
Along with relevant competence, and an understanding of the target application, the following points
should be considered:
4.1.1 Ensure that the information provided in this user manual is fully understood.
It is extremely important that the limitations and functionality of the EFL Relay are understood to
prevent incorrect installation and use from creating a potentially dangerous risk. If in doubt as to the
nature of the limitations or their implication, consult a competent authority such as a supervisor or
Ampcontrol technical representative.
4.1.2 Ensure that the application into which the EFL Relay is being installed has been
properly defined, designed and approved.
Any system intended to mitigate the risk of injury needs to be properly designed and implemented.
Such a system must be the result of structured risk analysis with the outcomes used to define the
system requirements. These requirements, in turn, will guide the choice of instrumentation, logic
solvers and actuators needed to implement the system. Understanding the needs of the system will
ensure proper selection of equipment.
4.1.3 Ensure that the EFL Relay will properly perform the required functions within the
system design.
It is important to understand how the EFL Relay is intended to interact with other equipment within a
system. For safe and reliable use, it is crucial that neither the EFL Relay logical operation nor its
signalling be compromised by incompatibilities with connected equipment.
4.1.4 Modifications of any form to the EFL Relay are prohibited.
The EFL Relay, as supplied, has been designed and manufactured to comply with the requirements of
protection standards. If modifications of any form are made to the EFL Relay, the equipment may no
longer be fit for use. If any modifications or damage to the EFL Relay is evident, do not use the
equipment and contact Ampcontrol for advice.
