SAFETY INSTRUCTIONS FOR INSTALLATION, USE and MAINTENANCE
The installation and maintenance of DATEXEL Associated Apparatus must be made in compliance with the Standards relative to electric
installations in hazardous areas. Before install the device, read carefully the relative instructions sheet and respect the following standards:
Hazardous areas with GAS atmosphere and Combustible Dust (not mines)
- Standard EN 60079-14 (current edition) for choice and installation of the equipments.
- Standard EN 60079-25 (current edition) for intrinsically safe Systems.
(note: every "typology" of Ex i system must be described in a "System description" document ).
- Standard EN 60079-17 (current edition) for check and maintenance.
To guarantee a correct and safe operation of devices, respect the following requirements:
1) All devices connected to the output and power supply terminals and to relays must be subjected at a maximum voltage of
250 Vrms (Um). The power supply voltage value must be included between 20 and 30 Vdc.
2) The devices must be installed in a SAFE AREA or in hazardous area if them have been closed in an explosion proof enclosure.
Moreover , it is necessary to connect the devices in applications that guarantee them a minimum grade of protection
IP20 for internal places, or IP54 for external places.
3) Repair of devices and substitution of protections must be executed only by DATEXEL s.r.l.
