3 INSTALLATION
3.1 General Warnings
These instructions have been designed to assist users of the MEC-1 relay with installation.
Before the MEC-1 can be installed, there are a number of things that need to be considered and understood to prevent incorrect
or unsafe operation of the MEC-1 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 MEC-1 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 MEC-1 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 MEC-1 relay will properly perform the required functions within the system design.
It is important to understand how the MEC-1 is intended to interact with other equipment within a system. For safe and reliable
use, it is crucial that neither the MEC-1’s logical operation nor its signalling be compromised by incompatibilities with connected
equipment.
3.1.4 Modifications of any form to the MEC-1 relay are prohibited.
The MEC-1 as supplied has been designed and manufactured to comply with the requirements of protection standards. If
modifications of any form are made to the MEC-1, the equipment may no longer be fit for use. If any modifications or damage to
the MEC-1 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 MEC-1. Failure to adhere to this information may give rise to
unsafe operation.
Using the MEC-1 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 MEC-1 must be powered within the specified voltage range.
• The installation of the MEC-1 must be carried out by suitably trained and qualified personnel.
• Identification labels fixed to the MEC-1 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 MEC-1. As supplied, the unit is built to, and complies with the
relevant standards. Modification to its construction will render the unit non-compliant.
• Complete and accurate records of the installation must be kept as part of the site installation.
