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 designed exclusively for operation in TN networks.
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 exclusively intended for operation in TN networks and only suitable for
use in supply grids. At 480V
AC
, the drive controllers are permitted to supply a maximum
symmetrical nominal short-circuit current in accordance with the following table:
Size Max. symm. nominal short-circuit current
Size 0 – Size 2 5000A
Size 3 10000A
Tab. 1: Maximum symmetrical nominal short-circuit current of the drive controller
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 the 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.
