DESCRIPTION
Essential Health and Safety Requirements:
The apparatus is designed in accordance with ATEX Directive
and EN/IEC 60079-0, EN/IEC 60079-7 standards.
This apparatus is designed to be installed in potentially
explosive atmospheres caused by gases, vapors or mists
of group II (category 3G).
G3 series are electronic control system intended to allow
Fieldbus connection to pneumatic manifolds.
Refer to the specific instruction and maintenance sheet
for 501 or 502 IECEx/ATEXseries.
Make sure that you understand all specific conditions of
use outlined in the "SPECIAL CONDITIONS FOR SAFE
USE" section.

SPECIAL CONDITIONS FOR SAFE USE:
The device must be installed in a control cabinet with
a protection degree of IP54 in conformance with stand-
ards EN/IEC 60079-0 and EN/IEC 60079-7.
For gas and dust application (Zone 2 and 22). The con-
trol cabinet must conform to EN 60079-31 additionally
with a protection degree of IP54 or IP65 minimum de-
pending on dust category.
A validation from a third party (Notified Body) about
the complete control cabinet is required for IECEx.
ASCO™ or NUMATICS™ or ASCO-NUMATICS™
components are intended for use according to the techni-
cal characteristics specified on the nameplate or in the
documentation.
The internal temperature of the cabinet may not exceed the
minimum temperature of -10°C and maximum of +50°C.
The cabinet must be constructed to withstand the full range
of ambient temperature, as well as the total energy con-
sumption of all installed electrical equipment.
Do not disassemble any component of the device ex-
cept when replacing spare parts. Only replacement with
identical IECEx/ATEX replacement parts is authorized.
Otherwise, the manufacturer's warranty will be invalidated.
The specifications of IP54 must be met when installing the
device in the cabinet. All fasteners and external electrical and
pneumatic connections must be sealed according to IP54.
Do not remove plugs from sockets when under power.
The wire cross section of the protective earth conductor
must equal the minimum wire cross-section of the power
conductor. Make sure there is an equipotential connection
via a cable between the apparatus and the control cabinet.
Max. supply voltage must not exceed 26.4 VDC.

Protection should be applied to limit the supply volt-
age to 140% of the rated voltage.
All 0 Volt from power supplies must be connected to
the ground.
The equipment shall only be used in an area of at least pol-
lution degree 2, as defined in IEC 60664-1 standard.
Electrical connections:
All plug connectors must be fitted with retention mechanisms
or friction retainers in accordance with EN/IEC 60079-7
standards.
Electrical connections must be secured by qualified per-
sonnel in order to ensure that they are not easily loosened
or twisted and that the contact pressure of electrical con-
nections remains constant during normal operation.
Safe electrical connections must be ensured before en-
ergizing the apparatus:
1- The appropriated plug connector must be used,
2- The male/female plug connector must be engaged
properly into its related female/male plug connector,
3- Tightening:
a. For Round connector type, the nut must be tightened.
b. For Terminal Strip connector type, the wires must
be properly fixed, so that the connection cannot
loose easily in case of tension of the cable.
Potential electrostatic charging hazard:
Precautions must be taken to guard against the ef-
fects of circulating currents generated by stray mag-
netic fields.
Avoid any build-up of electrostatic charges in the appa-
ratus.
When using replacement parts:
- Only use identical spare parts with IECEx/ATEX codes.
- Adhere strictly to the rules of disassembly and reas-
sembly in the instruction sheet.
- After assembling the replacement product, carry out a
mass continuity test as described in the instruction sheet
of G3 IECEx/ATEX.
Attention: failure to respect this replacement proce-
dure will invalidate the entire certificate for
the entire appliance.
OPERATION
In order to prevent material damage or physical injury,
do not touch the apparatus.
This may become hot under normal operating conditions.
