4. Screw the signal for blocking (e.g. door interlock or temperature blocking)
onto the supplied plug connector for X3 with a torque of 0.4 Nm. Tighten
the plug connector onto terminal X3 with a torque of 0.4 Nm.
5. Screw the wiring for the "Customer messages" interface (
ready
/
error
) to
the supplied plug connector for X5 with a torque of 0.4 Nm. Tighten the
plug connector onto terminal X5 with a torque of 0.4 Nm.
6.
DANGER!
Ensure that the connections PE, N, and L are not inter-
changed. Otherwise, dangerously high voltages could occur at the hous-
ing. Tighten (0.5 Nm) the control unit power supply to the plug connector
for X1 in accordance with the supplied connection diagram. In addition,
use the green cable housing supplied for touch protection.
7. The plug connector is coded. Carry out the installation without using force
by connecting the plug connector to terminal X1 correctly according to the
device labeling and screwing it tight with 0.5 Nm.
6.3.4 Switching on power supply
DANGER
Danger of explosion!
An incorrect position of the on-load tap-changer or the motor drive shaft can
lead to malfunction and, consequently, to an overload of the on-load tap-
changer. This overload can lead to an explosion in the transformer.
► Carry out automatic adjustment and trial tap-change operations on a volt-
age-free transformer.
► Supply the controller and motor-drive unit via a separate voltage source
during these tests.
► If a separate voltage source is not available, it is imperative that the cor-
rect position of the on-load tap-changer and motor-drive unit be checked
again according to the section "Mounting the motor drive" before these
tests.
Ensure that the transformer is idle.
To protect the loads from impermissible fluctuations in voltage, only activate
the load circuits (low-voltage busbar) after all tests are finished.
