4.7 Connecting the motor
Use a fitting device to fit the input or output elements.
Figure 4-2
The motor's rotor is dynamically balanced. The balance status is specified in the keyway:
H = Half-key balancing, F = Full-key balancing.
Adjust the balance of the transmission parts to be fitted to the rotor balancing. For half-key
balancing H, remove projecting, visible parts of the feather key.

General information on motor connection
Any work may only be carried out when the machine is stationary, isolated from the power
supply and secured so that it cannot be switched back on again. This also applies to
auxiliary circuits, e.g. anti-condensation heating
Checking safe isolation from power supply.
If the incoming power supply system displays any deviations from the rated values in terms
of voltage, frequency, curve form or symmetry, such deviations will magnify the increase in
temperature and influence electromagnetic compatibility.
Before starting work, make sure that a protective conductor is securely connected.
Connect the motor in such a way that a permanently safe electrical connection is ensured.
Wire ends must not protrude. Use matching cable end pieces.
Connect the supply voltage in the terminal box. Arrange the disconnecting link according to
the circuit diagram for star or delta connection in the terminal box.
Select the connection cables according to DIN VDE 0100. Take into account the rated
current and the plant-specific conditions.
