Safety instructions
DANGER
Voltage
The components of the control and the connections are under voltage. There is a danger of death on contact.
- Only allow work in which the control unit must be opened to be carried out by trained specialist personnel (electricians).
- Only perform work in which the control unit must be opened when the power supply is switched off.
- The five safety rules according to DIN VDE 0105 are to be observed:
- Disconnect from the mains
- Secure against reconnection
- Verify that the system is dead
- Carry out earthing and short circuiting
- Provide protection from adjacent live parts
DANGER
Defective product
A defect on the product can result in unforeseeable operating conditions. Persons may be injured.
- The product may only be operated in technically perfect condition in compliance with all chapters of the user manual.
- Environmental protection laws and safety regulations must be observed.
WARNING
Maintenance
Due to a fault condition, e.g. due to insufficient maintenance, parts of the product can be unexpectedly energised. This may result in electric shocks.
- The electrical installation is to be tested regularly. Loose connections and defective cables must be rectified immediately.
- Observe the maintenance intervals and maintenance regulations in this operating manual.
- Observe the maintenance intervals and maintenance guidelines from the manufacturer and the applicable guidelines.
- Components may only be replaced by spare parts of the same design. The specifications of the component manufacturers must be complied with during installation.
WARNING
Noise emission
When working on pressurised pneumatic supply, significant noise emission can occur. Acute and chronic loss of hearing may result.
- Never perform work on the pressurised pneumatic supply without hearing protection.
- Only replace the silencers when the supply is unpressurised.
WARNING
Displacement of atmospheric oxygen
In the event of inert gas leaks, displacement of atmospheric oxygen may occur. Danger of suffocation!
- The operator must ensure adequate ventilation and airing in all rooms with gas installations and monitor the oxygen content.
WARNING
Cross-contamination
Cross-contamination of the control air with process gases can result in the control unit being damaged.
- Ensure that cross-contamination of the control air line is prevented.
WARNING
Repairs
If the product is not used as intended, unpredictable operating conditions may occur. Serious personal injuries are possible.
- Repairs may not lead to a change in function. The system may not be tampered with or modified.
- Before each repair, the system must be depressurised and flushed through.
- Repairs are only permitted to be carried out by trained persons.
WARNING
Working on the product
If an accident occurs when working on the product, there is a considerable risk of injury.
- Never work on the product unattended or unannounced.
- Observe the site safety rules and permission procedure.
CAUTION
Injury or damage in the event of incorrect assembly or disassembly
Special steps are required for assembly and disassembly work on the product. Personal injuries and damage to the product are possible.
- Assembly and disassembly work may only be carried out by the installation engineer or appropriately skilled specialist companies and persons.
- The product is not permitted to be re-used following disassembly. All components must be disposed correctly.
CAUTION
Static discharge
Static discharges can occur in the event of contact between the control unit and persons or between parts of the electrical equipment. Injuries, shock responses and damage to the control unit are possible.
- Before commissioning, the operating firm must ensure that all electrical equipment is provided with equipotential bonding (earthing).
- The earthing function is to be tested on a regular basis. The intervals are specified by the operating firm in its risk assessment.
NOTICE
Lighting
Incorrect switching actions or confusion can occur due to inadequate lighting.
- Ensure sufficient lighting in accordance with the statutory regulations.
