Storage more than 12 months
♦ We recommend an inspection by the after-sales service of Systemair before commissioning.
Test the motor windings:
♦ Measure the insulation resistance of each motor winding against grounding at 500 V DC. The insulation resistance
must be > 10 mΩ.
Measures for an insulation resistance < 10 mΩ:
1. If the motor has drain plugs, remove them to allow any moisture to drain and replace them when the motor windings
are suitably dry.
2. Dry the motor in a warm dry airflow (typically 40 degrees Celsius).
3. Measure the insulation resistance of each motor winding against grouding at 500 V DC.
4. Repeat the aforementioned steps until the measurement outcome > 10 mΩ.
Test the motor:
♦ Connect an ammeter to each phase of the motor.
♦ Switch the fan on and check the current consumption.
♦ Compare the current consumption with the nominal consumption on the name plate.
