3.2 Switch cabinet layout
The positioning of the components in the switch cabinet has a significant e fect on the
trouble-free system and machine function. You should take into account the following
points in your planning:
•
Evaluate the assemblies used in relation to EMC.
•
Divide the switch cabinet into zones with different power and interference levels.
•
For devices susceptible to interfer
ence, maintain a distance of at least 200 mm
(7.87 in) from the following components:
− DC-AC Servo Drive
− Input and output chokes, transformers
− Mains, motor, DC power supply and braking resistor cables (even if shielded)
− Relay and contactors (even if interference-suppressed)
•
For small distances use separators for shielding; fasten the separators directly
and conductively to the backing plate.
•
If a motor contactor or motor choke is used, the component should be directly
positioned directly at the DC-AC Servo Drive.
•
Do not use fluo escent lamps in switch cabinets, as they emit high-frequency
interference.
•
Fit contactors, relays, solenoid valves, switched inductors and capacitors with
suppressors.
•
The mains filter must be mounted on the backing plate as close as possible to
the feed point and with large surface area contact. The backing plate must be
connected to the central earthing point with a low-impedance connection. No
unfilte ed cables are allowed to be laid on the mains input side of the filter so
that no interference can be coupled into the cables.
