Ifm electronic E7354A T splitter Operating instructions
Below you will find brief information for T splitter E7354A. The T splitter E7354A allows you to tap the AS-i voltage and external auxiliary voltage via the M2 socket (current rating 4 A). Ensure that when replacing the T splitter that the pierced points on the AS-i flat cable are either used again or are placed within the black seal area of the T splitter. It is the responsibility of the operator to check the suitability of the flat cables for use in hazardous areas, taking into account the environmental conditions (temperature, chemicals, etc.)

Functions and features
• Use in hazardous areas according to the classification
II 3G II 3D
(group II, category 3, apparatus for gas and dust atmosphere)
Complies with the standards EN60079-0, EN60079-15 and EN60079-31.
Marking
II 3G Ex nA II T6 Gc X
II 3D Ex tc IIIC T70°C Dc X
Installation / Set-up
The units must only be installed, connected and set up by qualified staff. The qualified staff must have knowledge of protection classes, regulations and provisions for apparatus in hazardous areas.
Check whether the classification (see "marking" above and marking on the unit) is suitable for the application. Adhere to the relevant national regulations and provisions.
• Permissible operating temperature of the application:
0 ... +60°C
With the T splitter the AS-i voltage and external auxiliary voltage can be tapped via the M2 socket (current rating 4 A).
Disconnect the power supply.
Important notes
Ensure when replacing the T splitter that the pierced points on the AS-i flat cable are either used again or are placed within the black seal area of the T splitter.
If no connector is fitted to the M12 socket (tightening torque 0.6...0.8 Nm) ensure that the protective cover is in place.

Tests with the following flat cables were carried out and passed successfully:
E74000, E74010, E74200, E74210 as well as all technically identical versions with different lengths.
The E74100 and E74110 flat cables as well as all technically identical versions with different lengths are not suited.
It is the responsibility of the operator to check the suitability of the flat cables for use in hazardous areas, taking into account the environmental conditions (temperature, chemicals, etc).

Special conditions for safe operation
• Avoid electrostatic charging on plastic units and cables.
• Do not mount the module in the dust flow.
• Avoid dust deposits on the splitter box.
• Avoid electrostatic charging, only clean the unit with a damp cloth. In principle, rubbing with non-conductive materials must be avoided.
• Avoid direct radiation with high UV components (sunlight), mount the unit in a protected place.
• The unit is rated for low impact energy (EN60079-0, table 8, 4 joules). Protect splitter box and cable against destruction.
• The unit with the M12 protective cover in place meets the requirements of the categories 3D and 3G.
• Use connectors which are suited for hazardous areas, e.g. ifm connectors
EVC**A with Ex certificate (certificate number BVS 08 ATEX E 109 U).
• Do not separate the module upper part from the FC lower part while live.
• Do not separate the M12 connectors when energised.
• When connecting an M12 connector ensure that the O-ring is present and undamaged in the socket.
• Check the tightening torque of the screws two weeks after mounting and retighten them, if necessary.
• Protective caps, housing upper and lower parts and M12 fittings may only be opened or closed in a sufficiently clean environment.

• For use in hazardous areas according to the indication compliance with the protection rating is essential. Therefore appropriate care must be taken when mounting the housing and the seals.
• Only use the supplied lower part and supplied seals.
• If only one cable duct is used, the other one has to be closed using the flat cable blank.
• Flat cables must be firmly laid. Loads on the entry caused by strain or movement of the flat cables must be avoided.
