1.10 Version with protection class IP55 / IP66
NORDAC SK 200E
frequency inverters and the additional modules are available in all sizes and in the
protection classes IP55 (standard) or IP66 (optional).
The protection class IP66 must always be stated when ordering!
There are no restrictions or differences to the scope of functions in either protection class. In order to
differentiate the protection classes, modules with protection class IP66 are given an extra “-
C
” (
c
oated
coated PCBs) in their type designation.

IP55 version:
The IP55 version of the SK 200E is the
standard
version. Both versions (motor-mounted, mounted on the
motor or wall-mounted on a wall bracket) are available. In addition, all adapter units, technology units and
customer units are available for this version.
IP66 version:
In contrast to the IP55 version the IP66 version is a modified
option
. Both variants (motor-integrated, close to
motor) are also available. The modules available for the IP66 version (adapter units, technology units and
customer units) have the same functionalities as the corresponding modules for the IP55 version.
NOTE
The modules for the IP66 design are identified by an additional "-
C
" and are modified
according to the following
special measures
listed below.
Special measures:
Impregnated PCBs, painted housing
Diaphragm valve for pressure compensation on temperature changes.
Low pressure test
A free M12 screw connection is required for low pressure testing. After successful testing, a
diaphragm valve is inserted here. This screw connection is therefore no longer available for
a cable gland.
NOTE
For all versions, care must be taken that the cable and the cable gland are carefully
matched. This is the only way to ensure permanent compliance with the required protection
class.
