finder 66 Series Power Relays 30A
GENERAL SAFETY INFORMATION
These safety instructions refer to the installation, utilization and maintenance of 66 series relays to be used in potentially explosive areas due to the presence of combustible GAS.
The information of these instructions are only for qualified personnel. The relays comply with the Essential Health and Safety Requirements applicable for ATEX Components, for potentially explosive atmospheres provided by European Standards: EN 60079-0 (2012+A11/2013), EN 60079-15 (2010)
TRANSPORT, STORAGE
On receipt verify that the relay has not been damaged during transport. If damaged, do not install and immediately advise the transport service.
INSTALLATION
Installation must comply with the rules of the standard EN 60079-14 or with the current national standards.
Before the installation in an explosive atmosphere, the installer must ensure that the relay is suitable for the classified area in consideration of the different inflammable substances present in the installation area (please verify the marking on the relay cover before installation).
The relay must be installed only by qualified people with knowledge of electrical apparatus for explosive gas atmospheres and electrical installations in hazardous areas and has to be done with the relay and equipment at standstill, electrically dead and locked against restart.
