INSTALLATION
These instructions have been designed to assist users of the ECD Relay with installation and special wiring techniques required
to maintain the integrity of the intrinsically safe circuits.
3.1
General Warnings
Before the ECD can be installed, there are a number of things that need to be considered and understood to prevent incorrect
or unsafe operation of the ECD 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:
3.1.1
Ensure that the information provided in this user manual is fully understood.
It is extremely important that the limitations and functionality of the ECD 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.
3.1.2
Ensure that the application into which the ECD 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.
3.1.3
Ensure that the ECD relay will properly perform the required functions within the
system design.
It is important to understand how the ECD is intended to interact with other equipment within a system.
For safe and reliable
use, it is crucial that neither the ECD’s logical operation nor its signalling be compromised by incompatibilities with connected
equipment.
3.1.4
Modifications of any form to the ECD relay are prohibited.
The ECD as supplied has been designed and manufactured to comply with the requirements of certification standards. If
modifications of any form are made to the ECD, the conditions of certification will no longer be valid and the equipment will no
longer be fit for use in a hazardous area. If any modifications or damage to the ECD is evident, do not use the equipment and
contact Ampcontrol for advice.
3.2
Mandatory Installation Practices
The following information must be adhered to when installing the ECD. Failure to adhere to this information may give rise to
unsafe operation and could render the product invalid against its certificate.
Using the ECD in a manner that exceeds its electrical, functional or physical specifications, or in a way that is contrary to its
operating restrictions, may create risks to personnel and/or equipment resulting in injury or death.
•
The ECD must be powered within the specified voltage range.
•
The installation of the ECD must be carried out by suitably trained and qualified personnel.
•
Certification and identification labels fixed to the ECD must not be damaged, removed or covered before, during or
after installation.
•
The installation is to be in accordance with the relevant installation Standards/Codes of Practice.
•
Modifications must not be made to any part of the ECD. As supplied, the unit is built to, and complies with standards
against which it has been certified. Modification to its construction will render the unit incompatible with its certification.
•
Complete and accurate records of the installation must be kept as part of the site installation.
