3.3 Residual Risks

3.3.1 Explosion Hazard

An explosion hazard cannot be entirely ruled out in hazardous areas despite the device

having a state-of-the-art design.

Perform all work steps in hazardous areas with the utmost care at all times!

Possible moments of danger (residual risks) can be categorised according to the following

causes:

Mechanical damage

The device can be pressed or scratched during transport, mounting or commissioning,

causing it to no longer be leak-tight. Such damage can, for example, render the device's

explosion protection partially or fully ineffective. This can result in explosions causing fatal or

severe injuries to persons.

Observe the weight and the maximum load-bearing capacity of the device;

see specifications on the packaging.

Transport the device only in the original packaging or in equivalent packaging.

Use transporting or lifting equipment which is suitable for the size and weight of the device

and can reliably carry the weight of the device.

Check the packaging and the device for damage. Report any damage to R. STAHL

immediately.

Store the device in the original packaging in a dry (no condensation) and stable position

which is safe from vibrations.

Do not damage the enclosure, built-in components or seals during mounting.

Excessive heating or electrostatic charge

Subsequently modifying the device, operating it outside of permitted conditions or failing to

clean it properly can cause it to heat up excessively or to become electrostatically charged,

causing it to produce sparks. This can result in explosions causing fatal or severe injuries to

persons.

Operate the device only within the prescribed operating conditions

(see the type plate and the "Technical data" chapter).

Only allow the manufacturer to paint the device and have this company coat it with special,

conductive paint.

Equip devices used outdoors in the elements with a protective roof or wall.

Regularly inspect the device for a material change (plastic). If any changes are identified,

test or replace the device.

Do not paint the device. Have all repairs performed by the manufacturer.

Comply with the area specification of EN IEC 60079-0 when fitting additional plastic

adhesive labels.

Clean the device only with a damp cloth.

Safety

Terminal Boxes

Series 8146/1, Series 8146/2

Impairment of IP protection

When installed properly and completely, the device will have the required IP degree of

protection. Making structural changes to the device or mounting it improperly can impair its

IP protection. This can result in explosions causing fatal or severe injuries to persons.

Only apply labels (on the outside) without drilling any additional holes.

Only drill holes for cable glands exactly according to the instructions in the

"Product selection, project engineering and modification" and "Mounting" chapters of

these operating instructions. Consult with R: STAHL first if there are any discrepancies or

uncertainties.

Mount the device only in the prescribed mounting position. More detailed explanations of

this can be found in the "Mounting" chapter.

Improper installation, commissioning, maintenance or cleaning

Basic work such as installation, commissioning, maintenance or cleaning of the device must

be performed only in accordance with the valid national regulations of the country of use and

only by qualified persons. Otherwise the explosion protection can be rendered ineffective.

This can result in explosions causing fatal or severe injuries to persons.

Have mounting, installation, commissioning and maintenance performed only by qualified

and authorised persons (see section 3.2).

Only make changes to the device in accordance with the instructions in these operating

instructions. Have R. STAHL or a test body (3rd party inspection) carry out acceptance.

Perform maintenance and repairs on the device only using original spare parts and after

consultation with R. STAHL.

Gently clean the device only with a damp cloth and without scratching, abrasive or

aggressive cleaning agents or solutions.

Never clean the device with a strong water jet, e.g. using a high-pressure washer!

3.3.2 Risk of Injury

Falling devices or components

The heavy device or components can fall during transport and mounting, causing severe

injury to persons in the form of bruises and contusions.

Use transporting and lifting equipment suitable for the size and weight of the device when

transporting and mounting it.

Observe the weight and the maximum load-bearing capacity of the device;

see specifications on the packaging.

Use suitable mounting hardware for mounting.

Electric shock

During electric installation, operation and maintenance, there will at times be high voltages

present at the device. Persons coming into contact with electric lines carrying excessively

high voltage can suffer severe electric shocks and consequently injuries.
