1 - SAFETY CONSIDERATIONS
1.1 - Safety guidelines
Installation, start-up and servicing of equipment can be hazardous 
if certain factors particular to the installation are not considered: 
operating pressures, electrical components, voltages, and the 
installation site (elevated plinths and built-up structures).
Only qualied installation engineers and fully trained technicians 
are authorised to install and start the equipment. 
All instructions and recommendations provided in the service 
guide, installation and operation manuals, as well as on tags and 
labels xed to the equipment, components and other accompanying 
parts supplied separately must be read, understood and followed. 
Failure to comply with the instructions provided by the manufacturer 
may result in injury or product damage.
 ■ Apply all safety standards and practices.
 ■ Wear safety glasses and gloves.
 ■ Use the proper tools to move heavy objects. 
 ■ Move units carefully and set them down gently.
CAUTION: Only qualified service technicians should be 
allowed to install and service the equipment.
1.2 - Safety precautions
Only  personnel  qualied  in  accordance  with  IEC  (International 
Electrotechnical Commission) recommendations may be permitted 
access to electrical components. 
It is particularly recommended that all sources of electricity to the 
unit should be shut off before any work is begun. Shut off the main 
power supply at the main circuit breaker or isolator.
IMPORTANT: The equipment uses and emits electromagnetic 
signals. Tests have shown that the equipment conforms to 
all applicable codes with respect to electromagnetic 
compatibility.
RISK OF ELECTROCUTION! Even when the main circuit 
breaker or isolator is switched off, specic circuits may still 
be energised as they may be connected to a separate power 
source.
RISK OF BURNS! Electrical currents may cause components 
to get hot. Handle the power cable, electrical cables and 
conduits, terminal box covers and motor frames with great 
care.
