2 Installation
2.1 Installation of units
A minimum clearance of 100 mm must be available above and below the units to ensure
unobstructed air supply.
The unit must be installed so as to be protected aga
inst
conductive dust accumulations and
vapours (degree of protection DIN 400S0-IPOO)
.
For mounting dimensions and location of the fixing points refer to the
dimension
drawings
NOTE
•
The front cover provides protection against contact with live parts according to DIN
VDE 0106, Part
7.
•
The unit's internal power supply for the fans is not potentially isolated from the mains
supply
.

2.2 Connecting instructions
The units are connected to the mains via an autotransformer or an isolating transformer.
When an isolating transformer is used, M200 on the power module must be earthed.
Depending on the transformer and unit size, an inrush current limiting circuit must be
prov
ided
if necessary (see
Section
2.3
" Inrush current limitation").

Connect the units as recommended by the manufacturer and in accordance with the circuit
diagram supplied by the customer. The current limiting circuit, the tacho input and the
current controller gain of the .unit must be matched to the type of motor
used.
For details
refer to
3.1
"Match
ing
the control system".
NOTE
•
The reference and actual value cables must be shielded and installed separately from
the power cables.
•
Twisted leads are recommended for the motor conductors.
•
The control cables for the controller enabling circuits must be inst al led separate f
rom
the contactor control
cables.
The chassis earth connection between the NC and the PWM drive should be kept as short as
possible using
minimum conductor
cross-sections
of
