Electric Noise; Installation Considerations - Danfoss AK-CC55 User Manual

User Guide | Controller for appliance control, AK-CC55

Electric noise

Cables for sensors, low voltage DI inputs and data communication
must be kept separate from other electric cables:
- use separate cable trays
- keep a distance between cables of at least 10 cm
- long cables at the low voltage DI input should be avoided

Installation considerations

Accidental damage, poor installation, or site conditions, can give
rise to malfunctions of the control system, and ultimately lead to a
plant breakdown.
Every possible safeguard is incorporated into our products to
prevent this. However, a wrong installation could still present
problems. Electronic controls are no substitute for normal, good
engineering practice.
Danfoss will not be responsible for any goods, or plant
components, damaged as a result of the above defects. It is the
installer's responsibility to check the installation thoroughly, and
to fit the necessary safety devices.
Special reference is made to the necessity of signals to the
controller when the compressor is stopped and to the need of
liquid receivers before the compressors.
Your local Danfoss agent will be pleased to assist with further
advice, etc.
