4.2 Requirements
This section describes the minimum recommended
requirements for mechanical installation. For UL and CE
requirements, see
chapter 5.2 Electrical Requirements for
4.2.1 Environmental
Refer to for information on required operating
temperature, humidity, and other environmental
conditions.
4.2.2 Cabinet
The kit consists of either 2 or 4 drive modules, depending
on the power rating. The cabinets have to meet the
following minimum requirements:
Width [mm (in)]
2-drive: 800 (31.5), 4-drive: 1600 (63)
Depth [mm (in)]
600 (23.6)
Height [mm (in)]
2000 (78.7)
1)
Weight capacity
[kg (lb)]
2-drive: 450 (992), 4-drive: 910 (2006)
Ventilation openings
See
chapter 4.2.5 Cooling and Airflow
.
Table 4.1 Cabinet Requirements
1) Required if Danfoss busbar or cooling kits are used.
NOTICE
EXTERNAL 230 V SUPPLY
An external 230 V supply is required for the SMPS
(switch mode power supply). Danfoss recommends using
a 6 A, 10 A, or 16 A slow-blow fuse when installing the
external supply.
4.2.3 Busbars
If the Danfoss busbar kit is not used, see
for the
cross-section measurements that are required when
creating customized busbars. For terminal dimensions, refer
to
chapter 7.8.2 Terminal Dimensions
and
.

NOTICE
Align busbars vertically to provide maximum airflow.
4.2.4 Thermal Considerations
For heat dissipation values, refer to
. The following heat sources must
be considered when determining cooling requirements:
•
Ambient temperature outside enclosure.
•
Filters (for example, sine-wave and RF).
•
Fuses.
•
Control components.
For required cooling air, refer to
.
