58 SERIES ATEX RELAY INTERFACE MODULE – SAFETY INSTRUCTIONS
GENERAL SAFETY INFORMATION
These safety instructions refer to the installation, utilization and
maintenance of 58 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 and the sockets comply with the Essential Health and Safety
Requirements for potentially explosive atmospheres provided by European
Standards:
EN 60079-0 (2012+A11:2013), EN 60079-15(2010), EN 60079-7(2015)

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.

TECHNICAL CHARACTERISTICS
CONTACT CHARACTERISTICS
- Contact configurations: 2 CO (58.32) – 3 CO (58.33) – 4 CO (58.34)
- Rated Current / maximum peak current: 10 / 20 A (58.32) – 9 / 20 A (58.33) – 6 / 15 A (58.34)
- Rated voltage / max switching voltage: 250 / 400 V AC (58.32) – 250 / 400 V AC (58.33) – 250 / 250 V AC (58.34)
- Rated load-Category AC1: 2500 VA (58.32) – 2250 VA (58.33) – 1500 VA (58.34)
- Rated load-Category AC15 (230 V AC): 500 VA (58.32) – 500 VA (58.33) – 350 VA (58.34)

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:
| INTERFACE | MAX PEAK CURRENT [A] (for pack) |
|---|---|
| 58.32….JK | 7 |
| 58.33….JK | 6 |
| 58.34….JK | 5 |
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.
