Wiring of wall adapter plate, size A
Fig. 32: Wiring of wall adapter plate, size A
1. Release the screw (1) to remove the contact plate (2)
from the adapter plate (3).
The (M6 x 12) PE connection (4) is underneath the
contact plate.
2. Guide the connection cable from the motor to the
adapter plate (3) through the integrated EMC screw
connection (5).
3. This PE connection (torque: 4.0 Nm) must be made to
the same ground potential as the motor.
The cross-section of the equipotential bonding line
must correspond to at least the cross-section of the
power cable.
DANGER!
Risk of death due to electrical shock!
Death or serious injury!
De-energise drive controller and secure it
against being restarted.
The drive controller must be grounded with
the motor according to relevant regulations.
The PE connection between the motor and
drive controller should be established using
the hexagon socket screw (4) and the spring
ring included in the scope of supply for the
adapter plate (3).
4. Wire the motor cable to contacts U, V, W (and the star
point in some cases) in the connection terminal, as
described in the "Basic connection versions"
chapter.

If there is a motor PTC present, connect to the
corresponding terminals of contact plate (2).
Replace the dummy screw connection (6) with a
suitable standard screw connection and guide the
connecting cable to the motor PTC into the adapter
plate (3).
IMPORTANT INFORMATION
Refit the contact plate (2) in the adapter plate (3).
Fasten the contact plate (2) using the screw (1)
(torque: 1.2 Nm).
