Mounting plate requirements
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
ƒ
contact surfaces.
If several mounting plates are used, ensure a large-surface connection between the
ƒ
mounting plates (e.g. by using earthing strips).
Mounting of the components
Connect the controller and RFI filter to the grounded mounting plate with a surface
ƒ
as large as possible.
No DIN rail mounting!
ƒ
Optimum cable routing
The motor cable is perfectly installed if
ƒ
– it is routed separately of mains cables and control cables,
– it crosses mains cables and control cables only at a right angle,
Cables must be routed close to the mounting plate (reference potential) as freely
ƒ
suspended cables act like antennas.
Cables must be routed in a straight line to the terminals (avoid "tangle of cables").
ƒ
Use separate cable ducts for power cables and control cables. Do not mix up
ƒ
different cable types in one cable duct.
Minimise coupling capacitances and inductances caused by unnecessary cable
ƒ
lengths and reserve loops.
Short-circuit unused cores to the reference potential.
ƒ
Route the positive and negative cables for DC 24 V close to each other over the total
ƒ
length to prevent loops.
Earth connections
Connect all components (drive controllers, chokes, filters) to a central earthing point
ƒ
(PE rail).
Set up a star-shape earthing system.
ƒ
Comply with the corresponding minimum cable cross-sections.
