Cooling; Terminal Box And Application Box; Fastening For Suspended Transport - Siemens SINAMICS G115D Operating Instructions Manual

Cooling

NOTICE
Dust deposits prevent heat radiation.
Dust deposits prevent heat radiation and cause a high housing temperature.
Keep the geared motor free from dirt, dust, etc.
The gearbox does not normally require additional cooling. The generously dimensioned
housing surface is sufficient for dissipating heat losses where there is free convection. If the
housing temperature exceeds a value of +80° C, please contact Technical Support.
The motor is designed to be cooled by means of fins. An external fan draws in the cooling air
through the aperture in the fan cover and blows the air over the surface of the stator
housing.
11.2.5

Terminal box and application box

The following are contained in the motor terminal box:
• Terminals for the motor (terminal board)
• Terminals for checking equipment
• Connection for brake
The number of available terminals is shown in the circuit diagrams. The circuit diagrams are
located in the terminal box.
11.2.6

Fastening for suspended transport

Motors may come loose during transport if not adequately secured
Do not use the integrally cast lifting eyes ① on the motor to transport the geared motors
due to the risk of breaking. Only use the integrally cast eyebolts ① to transport the motor
prior to mounting or following removal.
If necessary, use additional, suitable lifting accessories for transport or during installation.
When attaching by a number of chains and ropes just two strands must be sufficient to bear
the entire load. Secure lifting equipment so that it cannot slip.
