INSTALLATION
The GG2 Detector has been designed to connect and mount from compatible modules. Contact
Ampcontrol for the latest range of compatible modules.
NOTE
The GG2 is suitable for installation in Group 1 hazardous areas.
4.1 General Warnings
These instructions have been designed to assist users of the GG2 Detector with installation.
Before the unit can be installed, there are a number of things that need to be considered and understood
to prevent incorrect or unsafe operation of the unit 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 unit 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 unit 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 unit will properly perform the required functions within the system
design.
It is important to understand how the unit is intended to interact with other equipment within a system.
For safe and reliable use, it is crucial that neither the unit
’s logical operation nor its signalling be
compromised by incompatibilities with connected equipment. For Group I installations, a full Intrinsic
Safety Audit will be required, along with a correctly specified Safety File. Contact Ampcontrol for
engineering services to undertake these assessments.
4.1.4 Modifications of any form to the unit are prohibited.
The unit as supplied has been designed and manufactured to comply with the requirements of
protection and performance standards. If modifications of any form are made to the unit, the equipment
may no longer be fit for use. If any modifications or damage to the unit is evident, do not use the
equipment and contact Ampcontrol for advice.
4.2 Mandatory Installation Practices
The following information must be adhered to when installing the GG2 Detector. Failure to adhere to this
information may give rise to unsafe operation.
