6.3.4 Installation in the control cabinet

Mounting plate requirements

ƒ Only use mounting plates with conductive surfaces (zinc−coated or V2A−steel).

ƒ Painted mounting plates are not suitable even if the paint is removed from the

contact surfaces.

ƒ If several mounting plates are used, ensure a large−surface connection between the

mounting plates (e.g. by using earthing strips).

Mounting of the components

The trouble−free operation of power supply modules with an external brake resistor is only

ensured if an axis module is installed in the immediate vicinity. Preferably by end−to−end

mounting and use of the DC busbar system (X101/X102).

ƒ Connect the controller and RFI filter to the grounded mounting plate with a surface

as large as possible.

ƒ No DIN rail mounting!

Optimum cable routing

ƒ The motor cable is optimally installed if

– it is separated from mains cables and control cables,

– it crosses mains cables and control cables at right angles.

ƒ Always install cables close to the mounting plate (reference potential), as freely

suspended cables act like aerials.

ƒ Lead the cables to the terminals in a straight line (avoid tangles of cables).

ƒ Use separated cable channels for motor cables and control cables. Do not mix up

different cable types in one cable channel.

ƒ Minimise coupling capacities and coupling inductances by avoiding unnecessary

cable lengths and reserve loops.

ƒ Short−circuit unused cores to the reference potential.

ƒ Install the positive and negative wires for DC 24 V close to each other over the entire

length to avoid loops.

Earth connections

ƒ Connect all components (drive controllers, chokes, filters) to a central earthing point

(PE rail).

ƒ Set up a star−shape earthing system.

ƒ Comply with the corresponding minimum cable cross−sections.
