General information on dismantling

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

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.

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.
