• The Stabiliser is designed to operate within an ambient temperature range of -15
to 50°C - up to an altitude of 1000 metres. When installed in greater ambient
temperatures and / or altitudes, the maximum rating of the machine should be
derated by 2% for each additional °C, up to a max of 60°C, and 2.5% for each
additional 500 metres.
• OSES Stabilisers are forced air-cooled and the airflow paths should not be
obstructed.

exceed the temperatures stated above.
• For further information on cubicle sizing please refer to the Appendix Section 12.2
