➤ Allow only qualified and authorized electricians or trained personnel under the supervision of a
qualified and authorized electrician to carry out work on electrical equipment according to elec‐
trical engineering regulations.
➤ Before commissioning or re-commissioning the machine, the user must make sure there is ad‐
equate protection against electric shock from direct or indirect contact.
➤ Before starting any work on electrical equipment:
Switch off and lock out the power supply disconnecting device and verify the absence of volt‐
age.
➤ Switch off any external power sources.
These may include devices connected to the floating relay contacts.
➤ Use fuses corresponding to machine power.
➤ Check regularly that all electrical connections are tight and in proper condition.
Forces of compression
Compressed air is contained energy. Uncontrolled release of this energy can cause serious injury
or death. The following information concerns work on components that could be under pressure.
➤ Close shut-off valves or otherwise isolate the machine from the distribution network to ensure
that no compressed air can flow back into the machine.
➤ Depressurize all pressurized components and enclosures.
➤ Do not carry out welding, heat treatment or mechanical modifications to pressurized compo‐
nents (e.g. pipes and vessels) as this influences the component's resistance to pressure.
The safety of the machine is then no longer ensured.
Rotating components
Touching the fan while the machine is switched on can result in serious injury.
➤ Do not open the enclosure while the machine is switched on.
➤ Switch off and lock out the power supply disconnecting device and verify the absence of volt‐
age.
➤ Wear close-fitting clothes and a hair net if necessary.
➤ Ensure that all covers and safety guards are in place and secured before restarting.
Temperature
High temperatures are generated during compression. Touching hot components may cause inju‐
ries.
➤ Avoid contact with hot components.
These include, for example, the refrigerant condenser.
➤ Wear protective clothing.
➤ If welding is carried out on or near the machine take adequate measures to ensure that no
parts of the machine can ignite because of sparks or heat.
Operating fluids/materials
The used operating fluids and materials can cause adverse health effects. Suitable safety meas‐
ures must be taken in order to prevent injuries.
➤ Strictly forbid fire, open flame and smoking.
➤ Follow safety regulations when dealing with refrigerant and chemical substances.
➤ Avoid contact with skin and eyes.
