6.3 Special Conditions

6.3.1 Derating for Ambient Temperature and Switching Frequency

Ensure that the ambient temperature measured over 24 hours is at least 5 °C (41 °F) lower than the maximum ambient
temperature that is specified for the frequency converter. If the frequency converter is operated at a high ambient
temperature, decrease the continuous output current. For derating curve, see TR150 and TR170 Design Guide.

6.3.2 Derating for Low Air Pressure and High Altitudes

The cooling capability of air is decreased at low air pressure. For altitudes above 2000 m (6562 ft), contact Trane regarding
PELV. Below 1000 m (3281 ft) altitude, derating is not necessary. For altitudes above 1000 m (3281 ft), decrease the ambient
temperature or the maximum output current. Decrease the output by 1% per 100 m (328 ft) altitude above 1000 m (3281 ft)
or reduce the maximum ambient temperature by 1 °C (33.8 °F) per 200 m (656 ft).

6.4 General Technical Data

Protection and features
• Electronic motor thermal protection against overload.
• Temperature monitoring of the heat sink ensures that the frequency converter trips if there is overtemperature.
• The frequency converter is protected against short circuits between motor terminals U, V, W.
• When a motor phase is missing, the frequency converter trips and issues an alarm.
• When a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).
• Monitoring of the DC-link voltage ensures that the frequency converter trips when the DC-link voltage is too low
or too high.
The frequency converter is protected against ground faults on motor terminals U, V, W.
