5.3.5 Mounting the motor
Fixing by means of motor feet
● Select foot screws as per ISO 898-1 in compliance with the loading conditions and machine
type:
● Use foot screws with a minimum property class of 8.8.
● Pin the mounting feet to the customer foundation for motors with types of construction B6,
B7, B8, V5 and V6.

Flange mounting
The flange is only used to transfer the torque. Due to the empty weight or as a result of
vibrations that arise if the flange is too soft, the motor can be damaged if it is only fastened via
the flange.
1. Fasten the flange-mounted motors via a stable motor suspension and support them via the
end shield feet (foot flange type of construction).
2. During commissioning, ensure that the permitted vibration values are maintained in
accordance with ISO 10816‑3.
If the motor is to be only flange mounted, then the maximum speed n
max
is reduced for rigid
foundations according to the following table:

5.4 Connecting the cooling water supply
The inlet and outlet sockets for the cooling water supply are situated on the non-drive end in
the bearing shield area. On the bearing shield, there are two hexagonal couplers with a female
thread, which are each screwed onto a washer: At shaft heights of 180 and 225, hexagonal
couplers with

" female threads are used.
1. Only use valves, fittings and cooling water pipes made of rust-proof, stainless steel in the
cooling system.
2. Make sure that the cooling water meets the required cooling water specification, see section
headed "Cooling Water Quality" (Page 29).
