with the connection wires.
7. If they have not been pre-assembled at the factory, lead the connection wires of the voltage
sensors through the cable tube upwards into the low-voltage compartment or the operating
mechanism compartment. Connect the connection wires according to the circuit diagram.

DANGER
Voltage on the secondary side of the voltage transformer
Voltage on the secondary side of the voltage transformer leads to high voltage on the
primary side of the voltage transformer. Touching live parts leads to electric shock.
⇨ Separate the secondary wires of the voltage transformers from any voltage sources
before executing the installation work.
CAUTION
Heavy instrument transformer
An instrument transformer falling down can cause injury.
⇨ Lift the instrument transformer together with several persons.
⇨ Secure the instrument transformer against falling down.
The voltage transformers may already be pre-assembled in the panel when delivered. To install
the instrument transformers together with the connection cables, the voltage transformers must
first be removed.
