Danger of explosion and life or high damage
to property!
DANGER
All used components and accessory parts must fulfill the requirements for ex‐
plosion protection according to the 2014/34/EU directive.
The conditions on use given in this documentation must be taken into ac‐
count for any project planning and be observed during operation.
Notes about test number
The Ex designation for MSK motors can be identified by the "X" at the end of
the type plate or declaration of conformity. This identification is a note about
special conditions, which have to be observed with regard to the specified
safety and medical requirements of this underlying standards. Please ob‐
serve the following special conditions for a safe operation of the motors in
your construction:
●
The allowed ambient temperature is 0 … 40 °C.
●
It is not allowed to exceed the specified values of the tensile loading via
cables which are connected via connectors. The maximum permitted
values are determined in the following context.

Tensile load of cable gland (maximum values)
Danger of explosion by excessive tensile load
on cable glands
WARNING
Adherence of specified limits.
Mechanical fastening of cable ends after approx. 30 cm (e.g. cable
clamps, ...)
●
Maintenance and repair of motors have to be done by Rexroth service.
Ambient temperature
The maximum operating temperature is 155 ℃ on the motor housing at an
ambient temperature of 0 ... 40 ℃. The ignition temperatures of materials that
come into contact with the motors must be much higher than T=155 °C.
