Connection information for electrics

The electrical connection may only be undertaken by qualified electricians.

• Make sure that the details on the rating plate match the blower's connection values.
• Install appropriate overload protection (PTC thermistor triggering system) → Overload protection chapter and Maico’s range of accessories at www.maico-ventilatoren.com.
• Only connect blower in terminal box according to circuit diagram.
• Observe tightening torques for the terminal box’s screw connections.
• Motors <5.5 kW with full voltage, motors >5.5 kW with star/delta starter.
• A star/delta switch provided by the customer must be installed for blowers with a power consumption >5.5 kW in order to restrict the starting current. If desired, use a frequency converter or soft starter.
• For blowers controlled using frequency converters, use PTC thermistors to protect the motor from excessive motor temperatures. Running with frequency converters may result in higher vibrations and more noise.
• Install the command equipment needed for starting, stopping, emergency stops or resetting after an emergency stop in compliance with the relevant standards (EN 60204-1, EN 14118, EN 14119, EN 14120).
