2.3 Scope of supply
The scope of supply includes:
• the controller 48x_E
• set-value potentiometer 10 kΩ
• the operating instructions
2.4 Application as directed
• The controllers of the types 48x are electrical equipment for the
installation into control cabinets of electrical systems or
machinery.
• The controllers of the types 48x are designed as components
for the control of speed-variable drives with separately-excited
DC motors or for the assembly with other components to form a
machine or system.
• Drive systems with drive controllers 48x which are installed
according to the definition of a CE-typical drive system (see chapter
4.2.2), correspond to the EC EMC Directive and the standards
mentioned below.
• CE-typical drive systems are
- suitable for the operation on public and non-public mains and
- provided for industrial applications.
• Because the ground potential reference of the RFI filters the CE-
typical drive system which is described is not suitable for the
connection to IT mains (mains without ground potential reference).
• The drive controllers are not domestic appliances, but are designed
for drive systems for commercial use.
• The controllers of the types 48x themselves are not machines
according to the EC Machinery Directive. The final function is
only determined when integrated into the machine construction
of the user.
• The user must consider measures in his machine construction
which limit the consequences in case of malfunction or failure of
the drive controller (increase of the motor speed or sudden
motor stop) so that hazards for persons or material assets
cannot be caused, such as:
− further independent equipment for the monitoring of safety-
relevant variables (speed, travel, end positions, etc.)
− electrical or non-electrical protective equipment (latching or
mechanical blocking)
− measures covering the complete system
