To shield signal cables, we need to consider the following rules:

1) A maximum of 20 mm of wire can be seen outside the end of the screen

2) The screen should be grounded directly through the spring pressure clamp, or use a tail grounding less than 20mm in length. if

Through the capacitor ground, the length of the capacitor leg should be as short as possible.

3) At only one point, the grounding of each shielded network should be directly grounded.

4) All other ground points shall be grounded through 0022 microF/250 V AC (1000 V DC)

A capacitor. Property: Application: Y-type filter capacitor, i.e. installed in

Live and grounded; Design: Metal paper (self-healing); Capacitance: 0022 microF; Voltage: 250 V

Ac (1000 volts DC). Example: Evox Rifa, PME 271 0022 microF.

5) Direct grounding of the screen is carried out in the control system module DARA 1000/1001/1010.

Do not install any terminal boards in the cabinet/panel. Shielded cables should be connected directly to the DARA 1000/1001/1010 and its accompanying spring pressure clamp. Example: Pulse

Encoder for crane on trolley. Example: PTC for crane travel motor.

6) For shielded cables from DARA to the transducer that do not pass through any junction box, please

Shielded cable shielded isolation mark at transducer end. This cable must be fixed directly to

CI861/3BSE058590R1 should be constructed using a crane or conduit instead of laying on cable ladder racks. For example: PTC for crane driving motor.

7) For cables routed through junction boxes, factory suitable shielded cables need to be used several times

Floral part of the responsibility. The next page describes how to design a junction box.

8) For the shielded cable from the junction box of the trolley to the sensor, leave a cable shielding isolation remark

At the end of the transducer. The cable must be fixed directly to the steel structure of the crane or conduit

Should be used instead of, for example, laying on cable ladder racks.

9) Separate the unshielded end of the shielded cable from other control voltages and supply voltages.

10) If possible, bring signals from the same transducer close to each other in the cable.
