Frequently Asked Questions - AC005A IFM

How to install the AC005A module in an ATEX zone?

The module must be installed by competent personnel on a 35 mm profiled rail or mounting plate. Use the supplied socket and the yellow flat cable AC4000. Tighten the screws crosswise to 0.8 Nm. Observe the ambient temperature of 0 to +40°C and avoid electrostatic charges.

Which cable to use with the module?

Use exclusively the yellow flat cable AC4000 supplied by the manufacturer. Any other cable could compromise ATEX safety.

What is the tightening torque of the screws?

All screws, plugs and M12 nuts must be tightened to a torque of 0.8 Nm. Check the tightness after 2 weeks and retighten if necessary.

Can the module be cleaned with a dry cloth?

No, clean only with a damp cloth to avoid electrostatic charges. Do not rub with non-conductive materials.

What is the permitted ambient temperature?

The admissible ambient temperature is 0 to +40°C, depending on the maximum output power.

How to seal unused sockets?

Use plugs of type AC3004 to seal unused M12 sockets. Tighten to a torque of 0.8 Nm.

Is it possible to repair the module in case of failure?

No, no repair is possible. In case of failure, contact the manufacturer.

What to do in case of module failure?

Please contact the manufacturer (IFM) or your dealer. Do not attempt any repair.

What are the special conditions for safe operation?

Avoid electrostatic charges, direct UV radiation, installation in a dust flow, and protect the device against impacts (max impact energy 2 joules).

Can the module be mounted on a rail?

Yes, it can be mounted on a 35 mm profiled rail or directly on a mounting plate.

- Fulfils the requirements of the standards EN50014, EN50021 and EN50281-1-1.

- Marking

II 3G EEx nA II T6 X

II 3D T 60°C X IP67

Installation /Set-up

The units should only be mounted, connected and put into service 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.

- Permissible operating temperature of the application (referred to the maximum power which can be supplied):

0 ... +40°C

Installation remarks/Mounting

• Adhere to the relevant national regulations and provisions.
• Mount the module onto a wired FC lower part and then onto a 35mm rail or fasten it onto a suitable mounting surface.
• To observe the specified protection class, the 4 screws of the upper part must be tightened evenly crosswise with 0.8 Nm. When mounting the module ensure that the seal is carefully inserted. Only use the supplied lower part and supplied seals. Only use the yellow AS-i flat cable AC4000.
• During installation and laying the bending radii of the cables must be such that neither the cable entries nor the seals are subjected to mechanical stress.

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 module.
• 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 at a protected place.
• The unit is rated for a low impact energy (EN50021, table 13, 2joules). Protect the unit and cable against destruction.
• Insert the blanking seals in the supplied module lower part if the module is connected at the end of the cable line. The end of the flat cable must be located inside the module.
• Cover any unused sockets with protective caps (AC3004), tightening torque 0.8 Nm.
• Do not separate the module upper part from the FC lower part while live.
• Do not disconnect the M12 connections while live.
• Use M12 connectors with hexagon nuts, tightening torque 0.8 Nm.
• Check the tightening torque of the screws two weeks after mounting and retighten them, if necessary.
• Protective caps, housing upper / lower part and M12 nuts may only be opened or closed in a sufficiently clean environment.

• Using an FC lower part with addressing socket is not permitted.

• 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, see installation instructions / mounting.

• Only use the supplied lower part and supplied seals.

Maintenance /Repair

The unit must not be modified nor can it be repaired. In case of a fault please contact the manufacturer.
