1.9 Version with IP55/IP66 rating
The SK 2xxE is available in IP55 (standard) or IP66 (optional). The additional modules are available in
IP55 (standard) or IP66 (optional) rating.
A degree of protection that differs from the standard (IP66) must always be specified in the order when
ordering!
There are no restrictions or differences in terms of functionality in the aforementioned degrees of
protection. The model designation is extended accordingly in order to distinguish between the degrees
of protection.

-C
Information
Cable routing
For all versions, make sure that the cables and cable screw connections at a minimum comply with the degree of
protection of the device and attachment regulations and are carefully matched. Insert the cables so that water is
deflected away from the device (if necessary, use loops). This is essential to ensure that the required degree of
protection is maintained.
IP55 version:
The IP55 version is the
standard
version. The two installation types
motor-mounted
(fitted onto the
motor) and
close to the motor
(fitted to the wall bracket) are available in this version. All connection
units, technology units and customer units are also available for this version.
IP66 version:
The IP66 version is a modified
option
of the IP55 version. Both installation types
(motor-integrated
,
close to the motor
) are also available for this version. The modules available to the IP66 design
(connection units, technology units and customer units) have the same functionalities as the
corresponding IP55 design modules.
