The item C 3-Series requires a 24V power supply for the electronic system. This power supply must be connected to the
ter24V and GND24V.
The power output stage is connected either to the terminals L1, L2, and L3 for the AC supply or to the terminals ZK+ and ZK-
for the DC supply.
The motor must be connected to the terminals U, V, and W. The motor temperature switch (PTC or normally closed contact) is
connected to the terminals MT+ and MT-, if the switch is integrated in one cable together with the motor phases. If an
analogue temperature sensor (e.g. KTY81) is used in the motor, the connection to [X2A] or [X2B] is realised via the encoder
cable.
The connection of the shaft encoder to [X2A] / [X2B] via the D-Sub connector is shown in a schematic manner in
The item Servo Positioning Controller C 3-Series must be connected to earth (ground) with its PE connector.
As a first step, the item Servo Positioning Controller C 3-Series must be completely wired. It is only then that the operating
voltages for the DC bus circuit and the electronic supply may be switched on. In the case of reverse connection of the
operating voltage connectors, excessive operating voltage, or accidental interchanging of the operating voltage and motor
connectors, the item Servo Positioning Controller C 3-Series will be damaged.

item C 3-Series – complete system
The complete item Servo Positioning Controller C 3-Series is shown in
14. The following components are required for the operation of the servo positioning controller:
Mains power switch (main switch)
Residual-current circuit breaker, type B (RCD), 300 mA AC/DC-sensitive (if required by an application)
Automatic circuit breakeritem Servo Positioning Controller C 3-Series
Motor with motor cable
Mains power cable
The parameterisation requires a PC with a serial port or USB port.
A slow-blow (B16), three-phase, 16A automatic circuit breaker must be installed in the mains power supply line.
