3.5 Operational environment and operation
The products are subject to sales restrictions in accordance with IEC 61800-3.
The products are not designed for use in a public low-voltage network that supplies residential areas. Radio-frequency
interference can be expected if the products are used in this type of network.
The products are intended exclusively for installation in control cabinets with at least protection class IP54.
Always operate the products within the limits specified by the technical data.
The following applications are prohibited:
§ Use in potentially explosive atmospheres
§ Use in environments with harmful substances as specified by EN 60721, such as oils, acids, gases, vapors, dust and
radiation
Implementation of the following applications is permitted only after approval from STOBER:
§ Use in non-stationary applications
§ The use of active components (drive controllers, supply modules, energy recovery units or discharge units) from third-
party manufacturers
The drive controller is designed exclusively for operation in TN networks or on wye sources. At a nominal voltage of 200 to
480V
AC
, they are permitted to supply a maximum differential short-circuit current in accordance with the following table:
Size Max. differential short-circuit current
Size 0 – size 2 5000A
Tab. 3: Maximum differential short-circuit current
The drive controller has a configurable restart. If the drive controller is designed for an automatic restart after energy
shutdown, this must be clearly specified on the system in accordance with DIN EN61800-5-1.
3.6 Working on the machine
Before all work on machines and systems, apply the 5 safety rules in accordance with DIN VDE 0105-100 (Operation of
electrical installations – Part 100: General requirements) in the order listed:
§ Disconnect (also ensure that the auxiliary circuits are disconnected).
§ Ensure power cannot be switched on again.
§ Ensure that everything is de-energized.
§ Ground and short circuit.
§ Cover adjacent live parts.
Information
Note that you can only determine that voltage is no longer present once the discharge time has elapsed. The discharge time
depends on the self-discharge of the drive controller. You can find the discharge time in the general technical data of the
drive controller.
