Safety Devices 

Measures such as the following are for the safety of the operating personnel: 

electrical connection with a protective conductor (operating mode S1) and an earthing 
plug 
“Hot Surface" label on the pump body - warning notice 
Connect the motor to a fixed electricity supply. 
Fit a suitable motor switch with a protective device into the cable supplying the motor 
Inert gas monitoring to detect leaks and diaphragm rupture 
(customer installation) 

The diaphragm pump must not be operated without these elements. 

1.6 

Meaning of the Warning notes 

Take note of the warning notices. They are in the following box: 

CAUTION ! / WARNING ! 

Hazard which may lead to serious injuries or material damage.
