Softing Linking Device –

Manual for Configuration, Installation and Maintenance

ATEX and IECex Certifications - Excerpt from the Instruction Manual

9.4 General requirements

a)If the notes stated in this excerpt are not observed or in case of inappropriate handling of the device, our liability is waived. In addition, the warranty on devices and spare parts does no longer apply.

b)The details of this instruction manual have to be observed as have to be the conditions for use and the applicable details stated on the marking and type labels of each equipment.

c)Any selection and operation of the device has to be done observing the acknowledged technical rules.

d)Suitable precautions have to be taken to prevent unintended actuation or not permitted impairment of the device.

e)Be aware that energised conductors are not to be disconnected! This can lead to danger of life if potentially explosive atmosphere is present there at that time.

f)The equipment is only approved for intended and appropriate use. In case of non-compliance, the warranty and manufacturer’s liability do no longer apply!

g)It has to be ensured that only such equipment is installed which complies with the types of protection applicable to the relevant zones!

h)All connected electrical equipment has to be suitable for the respective intended use.

i)The operator has to ensure protection against lightning in compliance with the locally applicable regulations.

j)Electrostatic aspects have to be considered when mounting the bus-modules.

k)The hazard of any objects falling onto the bus-module has to be prevented.

l)The equipment does not meet the requirements of impact protection. Thus, protection against impact energy and IP protection have to be provided at the place of use according to the requirements stated in section 26.4 of EN 60079-0

m)The equipment is defined as “instruments and apparatus of low energy” according to clause 23 of EN 60079-15; thus the requirement stated in sub-clause c, limiting the transient characteristic to 40% above the rated voltage, has to be adhered to when erecting the equipment.

9.5 Commissioning, installation

The linking device is to be mounted in a major system. Depending on the degree of IP-protection, an interval for cleaning the apparatus (dust settlement) has to be defined. Strict care has to be taken that only equipment is installed that complies with the types of protection relevant to the applicable zones and categories.

Other important facts to be observed:

a)The equipment has to be installed in a protective enclosure which meets the requirements for resistance to impact defined in EN 60079-0, cl. 26.4.2. This enclosure has to pass the environmental tests according to EN 60079-0 for the preferred ambient range, i.e. it has to be submitted to these tests (thermal endurance, impact and IP; this test sequence must be observed).

b)The equipment shall only be used as intended.

c)The FE connection of the apparatus has to be connected with the PE of the system.

d)The linking device is only to be operated in a fully mounted and intact enclosure; if the enclosure is damaged, the operation is not permitted.

e)If ambient temperatures exceed 58°C at the place of installation, it may occur that the temperatures of connecting cables strongly rise if those cables have been put in place in an unfavourable condition. In such cases, either measurements have to be performed to confirm that the service temperature of the cables are not exceeded (i.e. 80°C), or such variants have to be used that withstand temperatures of minimum 90°C.

f)When removing the packaging ensure that no dirt can enter the enclosure or the plugs.

g)The equipment has to be protected against accidental opening; a warning sign saying “WARNING

– DO NOT SEPARATE WHEN ENERGIZED” has to be installed near the plugs.

h)The connecting plugs have to be fastened using a torque of min. 0.3 Nm.

i)If any vibration during the operation may cause parts of the plugs to loosen, then the plugs have to be provided with a light firm varnish used for securing screws. An extraction force of 0.5 Nm has to be achieved at an equivalent thread.

j)Open or not securely closed sockets shall not be energised in the Ex-atmosphere!
