Danfoss VLT AQUA Drive FC 202 Design Guide

NOTICE!
Adjustable frequency drives with the MCB 112 option
have PTB-certied motor thermistor sensor monitoring
capability for potentially explosive atmospheres.
Shielded motor cables are not necessary when
adjustable frequency drives are operated with sine-wave
output lters.

Cabinet Options and Ratings
Danfoss adjustable frequency drives are available with
three dierent protection ratings:
•
IP00 or IP20 for cabinet installation.
•
IP54 or IP55 for local mounting.
•
IP66 for critical ambient conditions such as
extremely high (air) humidity or high concen-
trations of dust or aggressive gases.
3.1.9 Radio Frequency Interference
The main objective in practice is to obtain systems that
operate stably without radio frequency interference
between components. To achieve a high level of immunity,
it is recommended to use adjustable frequency drives with
high-quality RFI lters.
Use Category C1 lters specied in the EN 61800-3 which
conform to the Class B limits of the general standard EN
55011.
Place warning notices on the adjustable frequency drive if
RFI lters do not correspond to Category C1 (Category C2
or lower). The responsibility for proper labeling rests with
the operator.
In practice, there are two approaches to RFI
lters:
•
Built into the equipment
-
Built-in lters take up space in the
cabinet but eliminate additional costs
for tting, wiring, and material. However,
the most important advantage is the
perfect EMC conformance and cabling
of integrated lters.
•
External options
-
Optional external RFI lters that are
installed on the input of the adjustable
frequency drive cause a voltage drop. In
practice, this means that the full AC line
voltage is not present at the adjustable
frequency drive input and a higher-rated
drive may be necessary. The maximum
length of the motor cable for
compliance with EMC limits ranges from
1–50 m (3.3–164 ft). Costs are incurred
for material, cabling, and assembly. EMC
conformance is not tested.
