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, presence of electrical components and 
voltages and the installation site (elevated plinths and built-up 
structures). 
Only properly qualied installation engineers and highly qualied 
installers and technicians, fully trained for the product, are 
authorised to install and start-up the equipment safely. 
During all servicing operations all instructions and recommendations 
which appear in the installation and service instructions for the 
product, as well as on tags and labels xed to the equipment and 
components and 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 standard safety codes and practices.
 ■ Wear safety glasses and gloves.
 ■ Use the proper tools to move heavy objects.
 ■ Move units carefully and set them down gently.
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 be shut o before any work is begun. Shut o the main power 
supply at the main circuit breaker or isolator.
IMPORTANT: This equipment conforms to all applicable codes 
regarding electromagnetic compatibility.
RISK OF ELECTROCUTION! Even when the main circuit 
breaker or isolator is switched o, 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.
