Function and device design

DANGER
Explosion hazard due to improper use!
Non-compliance results in severe or fatal injuries.

• Use the device only according to the operating conditions described in these operating instructions.

4.1 Function
The breather is used for ventilation and pressure equalisation of explosion- protected equipment in hazardous areas. It is designed for installation in enclosures of the type of protection “Increased safety ‘e'” and “Protected by enclosure ‘tb'”.
The sealing ring is used for compensation of slight unevenness on the contact surface and for compensation of temperature fluctuations.

Commissioning

DANGER
Explosion hazard due to incorrect installation!
Non-compliance results in severe or fatal injuries.

• Check the device for proper installation and function before commissioning.
• Comply with the national regulations.

Before commissioning, ensure the following:

• Check the mounting and installation.
• Device must not be damaged.
• If necessary, remove foreign bodies.
• Check if all screws and nuts have been tightened firmly.

Operation

• In the case of closed enclosures, fluctuations in temperature can cause pressure differences between the inside of the enclosure and the atmosphere around the enclosure. The breather safely compensates for these pressure differences.
• The breather reduces the vacuum effect, which prevents water, dust and dirt from reaching the inside of the enclosure via the sealing systems. Less water or moisture in the enclosure means that less condensate is formed.
• Existing condensate collects at the lowest point in the enclosure. If the breather is installed correctly, the condensate can drain via the breather.

Maintenance and repair

WARNING
Risk of electric shock or malfunctioning of the device due to unauthorized work!
Non-compliance can result in severe injuries and material damage.

• Work performed on the device must only be carried out by appropriately authorized and qualified electricians.

WARNING
Risk of electric shock or malfunction due to polluted or clogged openings!
Non-compliance can result in severe or fatal injuries.

• Clean polluted or clogged openings.

10.1 Maintenance

• Consult the relevant national regulations to determine the type and extent of inspections.

• Adapt inspection intervals to the operating conditions.
  During maintenance of the device, check for the following at a minimum:

• Damage to the sealing ring

• Damage to or contamination of the fabric filter.

10.2 Maintenance

WARNING
Danger of electric shock due to energised parts!
