2.3 Scope of supply
The scope of supply includes:
• the controller 53x_E
• the operating instructions
• the set-value potentiometer 10 kΩ
• plug-in terminals
2.4 Application as directed
•
The controllers of the types 53x are electrical equipment for installation into
control cabinets of electrical systems or machinery.
• The controllers of the types 53x 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 53x 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 of 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 they are designed for
drive systems for commercial use.
• The controllers of the types 53x 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
