Connection
Danger!
The motor cable must be connected to the correct phase of the frequency inverter and the elevator
machine: U -> U / V -> V / W -> W.
If the actual direction of travel does not correspond to the selected direction, the turning direction of the
elevator machine must be changed in the frequency inverter con
fi
guration. If the motor cable is not
connected to the correct phase, control of the elevator machine is not possible. It can result in jerky
movements or uncontrolled acceleration of the elevator machine.

Protective earth connection
In accordance with EN 50178 section 5.2.11 and 5.3.2.1 the protective earth connection must have a
cross-section of at least 10 mm
²
. In the case of protective conductors < 10 mm
²
, an additional
protective conductor must be connected. The cross-section must correspond at least to the cross-
section of the protective conductor on the connecting cable.
Hexagon head screws M6 (see arrows) are available to connect the additional protective conductor.
Figure 5-3-6-01 - Protective earth connection
Figure 5-3-6-02 - Protective earth connection
When connecting the protective conductor (PE), make sure that it is connected correctly.
The contact
disc (1) must be on the painted surface to ensure contact with earth.
