No options can be retrofitted. All options must be recorded by NORD when ordering and before the
production process. The customer must not open the device at any time and does not need to. The
device is mounted by using mounting lugs that are freely accessible from the outside. The electrical
connection of mains, motor and signal cables is only possible via respective plug connectors. The
optionally available control elements (e.g. switches) are mounted in a freely accessible position.
Opening a defined blind plug is only required for the temporary connection of a diagnostic tool. The
diagnostic tools comprise:
• Parameterisation unit SK CSX-3H/ SK PAR-3H
• NORDAC

2.1 Installation
The devices are designed for an installation close to the motor and do not need a control cabinet due
to their protection class.
Distance from device: The devices require sufficient ventilation for protection against overheating
and must therefore not be covered.
Mounting can be immediately next to each other.
The required distances for the connection cable routing must be
maintained.
Installation position: • Vertical, i.e. bottom position of cable connection (power connection)
• Horizontal, i.e. top position of control elements and diagnostic LEDs
