Abb.2-1:
Hazard classification (according to ANSI Z 535)
The here described motors (components for Group II, Category 3G/3D) are only
allowed to be used in an area (ATEX directive 94/9EG, Appendix II, cap. 1.5.1),
●
where no explosive atmosphere can occur during normal operation, as
this is avoided by ventilation and monitoring.
●
where occasionally explosive atmosphere can occur in an event of fault
and this atmosphere can be eliminated and intercepted by the user im‐
mediately after appearance. Thus the explosive atmosphere appears
seldom and during a short period.
The same applies to the use of motors in zone 2 and zone 22.
These conditions for use are valid for motors according to ATEX classification
Group II, Category 3.
Danger of explosion! Danger of life or high damage!
⇒ Only the components and accessories described in this documentation are
allowed to be used for this motors.
⇒ Strictly observe the here described application notes for project planning and
keep them during operation.
The maximum operation temperature is 115°C on the motor housing at an am‐
bient temperature of 40°C. The ignition temperatures of materials that come
into contact with the motors, must be much higher than T=155°C.
The motors may be operated only with Rexroth IndraDrive drive control devices.
Drive control devices of other manufacturers are not permitted.
Ignition sparks can occur when motor connectors are disconnected or connec‐
ted under load.
Danger of explosion due to sparking!
⇒ Do never disconnect or connect connectors under load!
⇒ Before operating connectors, switch off the load and secure it against re-
starting.
Speed-controlled drive systems contain unavoidable discharge currents above
ground. For this reason the motors have to be grounded over the motor cable
