When the converter is installed in a dirty environment it is
recommended that an air filter is installed to clean the
incoming air to the converter. These converters are then
provided with cabinet bottom plates.
• Protection Class IP 31 with filter in air inlet/outlet
• Protection Class IP 41 with filter in air inlet/outlet
• Gland plate and bottom plate
• Fire resistant bottom plate
• Special Colour (only outside) acc. to RAL standard
• Heater
If the converter is installed in a cold or humid environment, a
heater is required to prevent condensation when the converter
is not in operation. The heater (50 W) requires a supply voltage
of 230 V.
• Lightening
Cabinet lightening and door switch
• Incoming Supply Section for Line-ups
For system drives, where many converters are installed in a
line-up, an incoming cabinet is required for customer cable
connection and AC power distribution to all converters. This
incoming section can be provided with the following options:
- only busbars for cable connection and power distribution
- busbars as above and a mains isolation switch
- busbars as above and an air circuit breaker
FOR FURTHER INFORMATION REFER PAGES 12 AND 15.
• Horizontal Busbars
In the event that many converters are installed in a line-up, an
AC horizontal bus bar system can be supplied to feed the entire
line-up from the incoming supply section. Copper busbars
as standard, current ratings available 1000 A, 2000 A and
3000 A.

Cabinet Design
The AC supply connections to the incoming
supply section can be made by cables or busbars
from the bottom of the cabinet. As standard, the
AC supply is connected with cables from the
bottom of the cabinet. The other connections
are available as options.
The cabinet is classified to IP 20/21 as standard
(Drive-MNS-cabinet).
