General safety references
When working on electrical/electronic components:
WARNING
Risk of electric shock!
Before working on the terminal box, module housing and electrical lines: Switch off the main switch and secure it against being switched on again!
Close the terminal box and the module housing before switching on again!
The compressor module may be damaged or fail!
Never apply any voltage to the terminals of CN1 to CN6, CN11, CN12 and CN23 to CN28 – not even for test purposes!
The voltage applied to terminals 1 and 2 of CN23 must not exceed 10 V!
The voltage applied to terminal 3 of CN1 must not exceed 24 V! Do no apply voltage to the other terminals!
Never apply voltage to the voltage outputs, not even for testing.
For work on the compressor:
CAUTION
The compressor is filled with a protective charge: Excess pressure 0.2 .. 0.5 bar nitrogen.
Risk of injury to skin and eyes.
Depressurise the compressor!
Wear safety goggles!
For work on the compressor once it has been commissioned:
WARNINGThe compressor is under pressure!
Serious injuries are possible.
Depressurise the compressor!
Wear safety goggles!
After replacing cylinder heads:
DANGERIncorrect installation can cause the cylinder head to burst!
Before commissioning the converted compressor, carry out a strength pressure test / tightness test.
