DANGER!

To prevent the risk of explosion, observe not only the safety

instructions in the operating instructions for operation in the

potentially explosive atmosphere, but also the following:

▶ Specifications on the type label concerning temperature class,

ambient temperature, degree of protection and voltage.

▶ Do not use device in areas where there is gas or dust with a

lower ignition temperature than indicated on the type label.

▶ Installation, operation and maintenance may be performed by

qualified technicians only.

▶ Observe the applicable safety regulations (also national safety

regulations) as well as the general rules of technology for con-

struction and operation.

▶ Do not repair the device yourself, but replace it with an equiva-

lent device. Repairs may be performed by the manufacturer

only.

▶ Do not expose the device to any mechanical and/or thermal

loads which will exceed the limits described in the operating

instructions.

▶ Use only cable and line entry points which have been approved

for the respective application area and which have been

screwed into place according to the associated installation

instructions.

▶ The cable glands may be used for the insertion of permanently

installed cables and lines only.

▶ Close all unnecessary cable glands with lock screws approved

for the potentially explosive atmosphere.

▶ Use pre-assembled cable glands according to the installa-

tion instructions supplied by the gland manufacturer. Before

start-up in the potentially explosive atmosphere, check

whether the cable gland, as described in the associated

installation instructions, has been installed.

Special conditions of use

▶ Do not use the device in dust atmospheres in which inten-

sive charging processes can be expected.

▶ Use the device only in an area with at least degree of soil-

ing 2, as defined in IEC 60994-1.

▶ Ensure that the transient protection has been set to a value

which does not exceed 140 % of the measured peak voltage

value at the supply connections of the device.

▶ If devices feature a circular plug connection (multipole), the

mating plug will be provided by the end user and is not an

object of the approval. The mating plug must satisfy the

relevant requirements of the IEC 60079-0, IEC 60079-7 and

IEC 60079-31 and must have at least housing degree of

protection IP65 according to IEC 60529.

▶ If devices feature a circular plug connection (multipole), use

a special locking clip which prevents the plug from being

loosened without a tool.
