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.

Optimised screening connection
The elevator machine is supplied with an EMC cable gland.
The motor cable shielding must be exposed over a length of at least 10 mm.
The motor cable must be positioned so that the contact springs (2) of the EMC cable gland come into
contact with the exposed range (1). Check the contact with a continuity tester.
