 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 EN60079-14 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.

CHARACTERISTICS OF COIL

• Rated Voltage* (UN):
  12…230 V AC
  12…230 V DC
• Rated power AC/DC : 1.5/1 VA (50 Hz)/W
• Operating range:
  (0.8…1.1)UN AC
  (0.8…1.1)UN DC
• Ambient temperature : (−40…+70)°C

* Special rated voltages on request
The supply voltage depends on the characteristics of the timer

 SPECIAL CONDITION FOR SAFE USE

Maximum temperature recorded on the surface of the component (obtained suppling the coil at the nominal voltage, Tamb 70°C) not exceed 111°C with the value of rated current as described at the point 5. The wire connected to the terminals of the socket, must be at least 2.5 mm².
On multi-installation, the value of the nominal current is reduced depending on the model of the interface. A pack connection of 5 interface, power supply = rated voltage,
T.amb = 70°C:

The component must be inserted in an enclosure that meets the general requirements for enclosures listed in paragraph 4.10 of EN 60079-7. Connections must be carried out according to the requirements in paragraph 4.2.2 of EN 60079-7.

  MAINTENANCE AND REPAIR

The user must not open, modify or repair this relay in any way.
