1) The installation mechanics can sporadically influence the accuracy of the overall system.
Remark: These motors are suited for applica-
tions with STO safety function within the electric
drive system with ctrlX DRIVE according to
EN IEC 61800-5-2.

Degree of protection

The protection type according to EN 60034-5 is
determined by the abbreviation IP (International
Protection) and two code numbers for the degree
of protection. The first code number stands for
the degree of protection against contact and
ingress of foreign bodies. The second code
number stands for the degree of protection
against ingress of water.

The standard design for a non-positive shaft-hub
connection without play and excellent smooth
running. Use clamping sets, pressure sleeves or
clamping elements for coupling the machine ele-
ments to be driven.
The shaft sealing ring affects the degree of pro-
tection. We recommend regular visual inspec-
tions on shaft sealing rings. Depending on oper-
ating conditions, signs of wear may appear after
5,000 operating hours. If necessary, replace the
shaft sealing rings.
Attachment of drive elements
The mode of balancing of drive elements must be
adjusted to the motor. Observe the notes about
Type
mounting drive elements.
