4.2
Conditions for Use of MSK Motors according to ATEX Classi‐
fication, Equipment Group II, Category 3.
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. Please observe the following spe‐
cial conditions for a safe operation of the motors in your construction:
●
The permissible ambient temperature range is 0 ... 40°C. Higher ambi‐
ent temperatures up to max. 55 °C are allowed at corresponding derat‐
ing
chapter 10.1.1 "Installation altitude and ambient temperature" on
.
●
Servicing and repairs are only permitted by the certified Rexroth service.
●
It is not allowed to exceed the specified values of the tensile loading via
cables which are connected via connectors. The maximum allowed val‐
ues are determined in the following context.
F
Z max
Tensile load of connection cable (maximum value)
D
Diameter cable outer jacket (maximum value)

load of connection cables
WARNING
Adherence of specified limits.
Mechanical fastening of cable ends (e.g. use cable clamps after approx. 30
cm, ...).
The following maximum tensile load must be kept when using ready-made
cables.
