♦In the event of contaminated cooling air (dust, fluff, aggressive gases and grease), which
might adversely affect the functioning of the frequency inverter, adequate counter-
measures must be taken, e.g. separate air feed, installation of filters, regular cleaning,
etc.
♦The units are designed for mounting in suitable card racks .
♦The unit must be mounted vertically.
♦Ensure unimpeded access of cooling air and egress of discharged air. Clearances for
incoming and outgoing air must be complied with.
♦If the frequency inverter is continuously exposed to oscillation or vibration, vibration ab-
sorbers may be required.
2.7 Electrical Installation
♦The regulator contains components sensitive to electrostatics. Before installation and
service work in the terminal clamp area, the staff must free itself of electrostatic electricity.
The discharging can be achieved by touching a grounded metal surface beforehand.
♦To protect the power supply cables, the recommended cable protection fuse is required
♦The motor should be equipped with a temperature sensor . Evaluation can be performed
by the FU3AE-04 or a suitable analyser.

2.8 Information on EMC
In order to warranty electromagnetic compatibility (EMC) in your switch cabinets in an elec-
trically raw environment, the following EMC rules are to be observed during construction and
set-up:
♦All metallic parts of the switch cabinet are to be connected flatly and in a well-conducting
manner (not lacquer on lacquer!). If necessary, use contact or scraper wafers. The cabi-
net door is to be connected with as short a circuit as possible via the metal powder tapes
(upper, middle, lower).
♦Signal lines and power cables are to be laid separated from each other in order to avoid
coupling intervals. Minimum distance: 20 cm:
♦Signal lines should be led to the cabinet from only one level, if possible.
Unshielded lines from the same electrical circuit (outgoing and return circuit) are to be
transposed, if possible.
♦Contactors, relays and magnetic valves in the switch cabinet, if necessary in the adjacent
cabinets, are to be wired with suppressor combinations, e.g. with RC elements, varistors
or diodes.
♦The braiding from signal lines are to be laid two-way (source and target), large-area and
well-conducting to a ground1. In case of poor potential equalization between shielded
connections, an additional balancing network of at least 10 mm² must be laid parallel to
the braiding to reduce the current.
♦Wiring is not to be laid freely in the cabinet, but should rather lead as tightly as possible to
the cabinet frame or to installation plates. This also applies to reserve cables. At least one
end of them must be grounded, but preferably both (additional shield effect).
♦Unnecessary wire lengths are to be avoided. Coupling capacities and coupling induct-
ance’s are thereby kept small.
♦The braiding from leads, such as resolver or incremental tachometer cables, must be laid
to the frame grounding. Approximately 2 cm of the insulation is to be removed in the area
where the cable is to be led into the frame in order to expose the braided cable. The
braided cable may not be damaged while removing the insulation. The cable is to be led
at the position where the insulation has been removed by grounded terminals or taut sup-
ports.

clamping yoke
1Generally all metallic conducting parts which can be connected to a protective conductor,
such as cabinet frames, motor frames, foundation grounding, etc. are designated as a
ground.

2.9 Operation of the frequency inverter
Operate the frequency inverter only if it is in perfect condition. The permissible conditions of
use and output limits must be complied with.
Retrofitting, modifications or conversions of the frequency inverter are forbidden. In all such
cases, the manufacturer must be consulted.
The frequency inverter is an item of equipment for use in industrial installations. During op-
eration, these items of equipment have dangerous, live components. Consequently, during
operation all covers must be fitted to the drive controller, in order to ensure full protection
from contact with it.
The modules include electro statically sensitive CMOS und MOS components. Caution must
be exercised in respect of electrostatic charges.
2.10 Important instructions on protective earthing
Because of the loss currents of the essential mains filter (>3.5 mA) via the protective earth-
ing conductor (PE), according to DIN VDE 0160 the cross-sectional area of the lead-in wire
of the protective earth wire to the switch cabinet must be at least 10 mm² Cu, or a second
protective earth conductor must be laid electrically in parallel.
In the case of higher installed loads, the minimum cross-sectional area of the protective
earth conductor must be in a corresponding relation to the cross-section of the outer conduc-
tors (see DIN 57100 Part 540).
The loss currents of the filter may be as high as 100 mA. Operation with FI earth leakage
circuit breakers is therefore not possible.
2.11 Important instructions on routing of wires
Control lines and power cables must always be routed separately with a gap between them.
Tacho inputs, set point and analogue control inputs must be laid using shielded cables.
