Chapter 3 Installation and alignment
3.1 Preparations for installation
3.1.1 General
Good planning and preparation results in correct installation, assures safe running
conditions and maximum accessibility. During installation, general as well as
local safety instructions must be followed.
NOTE: Install anti-condensation heaters to keep the machine interior dry when
there is a risk of condensation.
NOTE: Protect the machine against dust and rain.
Tools and materials
Suitable material for set-up and shimming as well as other auxiliary tools for
installation are normally not included in the ABB delivery. Auxiliary tools for
installation are to be supplied by the customer.
The following should be available on site if required:
•
Attachments for gauges, extension brackets and other alignment tools.
•
A lever for turning the rotor.
•
Other auxiliary tools and materials for the installation, like hydraulic jacks
and bracket plates with adjusting screws.
General tightening torques
General tightening torques for screws is given in
Chapter 7.4.4. The tightness of
fastenings
. Use these values if no specific tightening torques are given in this
manual or in the mechanical and electrical drawings.
NOTE: The values in
Table 7-10. General tightening torques
are general, and do
not apply to various items, such as diodes, support insulators, bearings, cable
terminals or pole fastenings, surge arrester, capacitors, current transformers,
rectifier and thyristor bridges, or if some other value is given elsewhere in this
manual or in the mechanical and electrical drawings, see
Mechanical Drawings
and
Electrical Drawings.
3.1.2 Removal from storage
When bringing machine from the outside, at a temperature of below 0 °C, do not
do any work on the machine until its temperature has risen sufficiently (5 to
10 °C).
The transfer from a cold temperature to ambient temperature can cause
condensation inside machines and may be dangerous for the winding. It is
therefore important to check the winding insulation resistance before the start up
(see
Chapter 5. Commissioning)
.
3.1.3 Check of foundation
The structural design of the foundation is not included in the ABB scope, and the
customer or a third party is therefore responsible for this.
