Hydraulic - Connection of the Valve-Wires
The connection of the valve line may only be carried out in a voltage-free state! The terminal for
the connection of the valves can be found on the terminal block X1 /
(wiring diagram sheet 1 of
8)
. Check the valve voltage according to the rating plate and the data in the circuit diagram! For
DC voltage, Valves must be equipped with varistors!

Hydraulic - Optional - Connection of the Lower- /
Overpreasure-Contacts of the Aggregat
In the case of controlled hydraulic blocks, the evaluation is usually carried out via the
control electronics - see wiring diagram page 1 of 8!
Attention! The connection of the low / high pressure contact may only be carried out in
the de-energized state (230V AC)!
The terminal for connection is located on the printed circuit board X1 /
(Wiring diagram sheet 4 of 8).
The terminals are
1F and 1G.

Rope – Connection of the Brake-Coil-Wire(s)
Attention! The connection of the brake line may only be carried out in a voltage-free state! The
terminal for connection is located on circuit board X1 / (

Rope – Connection of the Motor-Wire
Attention! The connection of the motor cable must only be carried out in a voltage-
free state!
The motor cable is already installed in the control unit as standard for all KW controls.
It is designed as a flexible cable. In the case of frequency-controlled systems, the ca-
ble is equipped with a CU shield, which must be placed in a metal fitting on the motor
clamping box. If there is no metal screw connection, the shield must be twisted and
connected to the PE terminal (Pig-tail shielding) and a metal screw connection must
be installed immediately!

Mounting & Connection of the Brake-Resis-
tor
Attention! The connection of the brake resistor may only be carried out in a voltage-
free state!
The brake resistor wire is already installed in the control system as standard for all
KW controllers. It is designed as a shielded cable. The screen must be connected to
the cable clamp. The cable must be shortened if necessary and should not be placed
in squiggles (EMC interference!).
