Mechanical and electrical connections are made after the installation and alignment procedures.
The mechanical connections include the connection of air ducts, water tubes and/or oil supply
system where applicable.
The electrical connections include the connection of main and auxiliary cables, earthing cables
and possible external blower motors.
In order to determine proper actions, please read the Dimensional Drawing, the Connection
Diagram and the Data Sheet provided with the machine.
NOTE: Additional installation holes or threads should never be drilled through the frame, as
this may damage the machine.
The safety information in Safety Instructions at the beginning of the manual must be observed at
all times.
The electrical installation should be thoroughly planned before taking any action. The
connection diagrams received with the machine have to be studied before starting the
installation work. It is important to verify that the supply voltage and the frequency are the same
as the values indicated on the rating plate of the machine.
The network voltage and frequency should be within given limits according to the applicable
standard. Note rating plate markings and connection diagram in the terminal box. For additional
information, see the machine performance data sheet.
NOTE: Prior to installation work, it is important to check that the incoming cables are
separated from the supply network, and that the cables are connected to protective
earth.
NOTE: Check all rating plate data, especially the voltage and winding connection.
Electrical work must be carried out only by skilled persons. The following safety rules must be
applied:
• De-energize all equipment, including auxiliary equipment
• Provide safeguard against re-energizing the equipment
• Verify that all parts are isolated from their respective supply
• Connect all parts to protective earth and short the circuits
• Cover or provide barriers against live parts in the surrounding area
