Installation

4-14 UOMu_^MVMO

Screening D Connect the screen of the motor cable with the controller

- to the screen connection of the controller.

- additionally to the mounting plate with a surface as large as possible.

- Recommendation: For the connection, use ground clamps on bare metal mounting surfaces.

D If contactors, motor-protecting switches or terminals are located in the motor cable:

- Connect the screens of the connected cables also to the mounting plate, with a surface as large

as possible.

D Connect the screen to PE, with a surface as large as possible.

- Metal glands at the motor terminal box ensure a connection of the screen and the motor

housing.

D If the mains cable between mains filter and controller is longer than 300 mm:

- Screen mains cables.

- Connect the screen of the mains cable directly to the inverter and to the mains filter and connect

it to the mounti ng pla te with as large a surface as possible.

D Use of a brake chopper:

- Connect the screen of the brake resistor cable directly to the mounting plate, at the brake

chopper and the brake resistor with as large a surface as possible.

- Connect the screen of the cable between controller and brake chopper directly to the mounting

plate, at the inverter and the brake chopper with a surface as large as possible.

D Screen the control cables:

- Connect both screen ends of the digital control cables.

- Connect one screen end of the analog control cables.

- Always connect the screens to the screen connection at the controller over the shortest possible

distance.

D Application of the controllers 821X/822X/824X in residential areas:

- Use an additional screen damping

³ 10 dB to limit the radio interference. This is usually

achieved by installation in enclosed and grounded control cabinets made of metal.

Grounding D Ground all conductive metal components (controller, mains filter, motor filter, mains choke) using

suitable cables connected to a central point (PE bar).

D Maintain the minimum cross-sections prescribed in the safety regulations:

- For EMC, not the cable cross-section is i mportant, but the surface and the contact with a

cross-section as large as possible, i.e. large surface.
