5.1 Cooling
• The frequency converter is cooled by means of air circulation. To protect the unit from
overheating, it must be ensured that the ambient temperature does not exceed the
maximum temperature stated for the frequency converter and that the 24-hour
average temperature is not exceeded.
• Derating for temperatures between 40°C (104°F) and 50°C (122°F) and elevation 1000
m (3300 ft) above sea level must be considered.
• Improper mounting can result in overheating and reduced performance.
CAUTION:
During the normal operation, the heat sink surfaces may be so hot that only the buttons
should be touched to avoid burns.
5.2 Lifting
• Check the weight of the unit to determine a safe lifting method.
• Ensure that the lifting device is suitable for the task.
• If necessary, plan for a hoist, crane, or forklift with the appropriate rating to move the
unit.
• For lifting, use hoist rings on the unit, when provided.
5.3 Mounting
• Install the unit on the motor fan cover. Keep motor cables as short as possible. Check
the motor characteristics for actual tolerances.
