for smooth, vibration-free operation of the motor.
Complete balancing of the motor with the output element may be required.
Note the information and evaluation criteria to ISO 10816.
▪
Foot/flange mounting
Use the thread sizes specified by EN 50347 for fastening the foot and flange of
the motor to the foundation and to the motor flange respectively. Fasten the
motor at four foot holes or flange bolt holes positioned in rectangular
arrangement to each other. The customer is responsible for selecting the
strength of the fastening elements.
Property class recommendations:
Class 5.6 or higher for fastening elements for
motors with shaft centreline height up to and including 160 mm, and class 8.8 or
higher for motors with shaft centreline height 180 mm.
NOTE
Lifting lugs that have been screwed in must either be tightened or removed after
installation.
5.3 Electrical connection
DANGER
Hazardous voltage
Danger of death from electric shock!
▷
Have all work performed only by qualified specialist personnel and only when
the drive is at a standstill and secured against unintentional start-up. This also
applies to auxiliary circuits (e.g. standstill heater).
▷
The drive must not be electrically connected at any point in time when work is
performed on the open terminal box.
WARNING
Incorrect connection to the mains
Damage to the mains network, short circuit!
▷
Observe the technical specifications of the local energy supply companies.
NOTE
Always protect three-phase motors with a current-dependent overload protection
device with additional phase failure protection.
Select the motor connection cables in accordance with IEC 60364, taking into account
the current load of the cable at the given ambient temperature and the requisite
heat dissipation to IEC / EN 60204-1 as a result of cable routing.
5.3.1 Motor connection inside the terminal box
Observe the following when performing any work on the terminal box:
▪
Always use the original sealing element to close the terminal box so that it is dust
tight and watertight.
▪
Do not damage any components inside the terminal box, such as terminal board
and cable connections.
▪
Ensure that no foreign matter, contamination or moisture are present in the
terminal box. Terminal box cable entries to DIN 42925.
