Overload Protections
The compressor overload and start protection cuts off power to the compressor if the compressor speed drops below approximately 1,900 rpm, or if this motor speed is not reached during the start sequence. Possible reasons for overload protection activating could be too high refrigeration system pressures during operation or lack of pressure equalizing at start.
The fan overload protection stops the compressor if the fan current exceeds 0.5 A (avg) or 1 A (peak).
An overheating of the electronic unit heat sink will cause the compressor to stop. Restart will occur automatically when a normal temperature has been reached. If a fan is installed, it will continue to run when the compressor stops due to overload or electronic unit overheating.
Voltage Protection
If a voltage outside any concerned range is applied to the electonic unit, the compressor does not start, or it stops if the voltage limit is exceeded during operation. The compressor will restart automatically approximately 1 minute after the supply voltage has reached the reset voltage within the range in question.
Battery protection
The Danfoss electronic unit provides protection as follows:
Standared Battery Protection Settings
12V | 12V |
10.4 | 11.7 |
Final Installation Notes
For all appliances, AVOID the use of any electrical adapters or extension cords.
After installation, allow the appliance to sit for at least one hour before starting.
The manufacturer assumes no responsibility for any injuries or damage caused by noncompliance with any of the installation regulations.
