4.
Lift the main terminal box directly onto the machine frame at the position where the main
terminal box has to be connected (see Dimension Drawing included in the project
documentation).
5.
For NEMA main terminal box only: pull the stator cables through the ceiling membrane.
6.
Connect the main terminal box with the screws delivered with the machine frame. Make
sure that the isolation sealing is available to the connection surface of the machine
housing.
7.
Tighten all screws with max. 200 Nm. (see
Table 7-2 General tightening torques
).
For NEMA main terminal box only: After connecting the main terminal box mechanically to the
machine housing, the stator cables are connected to the terminals:
1.
Check the markings of the stator cables and the terminals.
2.
Connect the stator cables to the corresponding terminals according to the cable markings
(U1, V1, W1 or L1, L2, L3). See the Electrical Connection Diagram for more information.
3.
Tighten the preinstalled screws with max. 80 Nm. (see
2.5.2 Installation of cooler parts
If the cooler or parts of the cooling system (for example silencer, air lead channel) are delivered
separately, they have to be installed on site according to the following instructions.
1.
Open the package of the cooler/cooler parts and lift the part(s) using a suitable lifting
device (for example a crane) from the lifting eyes of the package.
2.
Check that all connection parts are free of dust and dirt.
3.
Check the correct installation positions from the Dimension Drawing delivered with the
project documentation.
4.
Check that all connection parts, bolts, washers and nuts are included in the delivery.
5.
Lift the cooler part to its correct position and connect it with the delivered installation
parts. Make sure that all sealing parts are installed at correct locations.
6.
Tighten all screws with max. 80 Nm. (see
Table 7-2 General tightening torques
2.6 Storage
2.6.1 Short term storage (less than 2 months)
The machine should be stored in a proper warehouse with a controllable environment. A good
warehouse or storage place has:
•
A stable temperature, preferably in the range from 10ºC (50°F) to 50ºC (120°F). If the
anti-condensation heaters are energized, and the surrounding air is above 50ºC (120°F), it
must be confirmed that the machine is not overheated
•
Low relative air humidity, preferably below 75%. The temperature of the machine should
be kept above the dew point, as to prevent moisture from condensing inside the machine. If
the machine is equipped with anti-condensation heaters, they should be energized. The
operation of the anti-condensation heaters must be verified periodically. If the machine is
not equipped with anti-condensation heaters, an alternative method of heating the machine
