Inverters-FREQROL-A800 Plus Series　-FREQROL-A800 Plus for CRANES- Easier maintenance

Easier maintenance

Enhanced vibration resistance Protection against vibration 

A strong vibration may occur in some operating conditions, for example, during the crane traveling. Inverters with enhanced vibration resistance are available. They have components fixed to the circuit board with adhesive and wires that are tied in place with cable ties.

Enhanced adhesion of the circuit board components
Components on the circuit board are fixed with adhesive for enhanced vibration resistance.

Enhanced countermeasure of connector coming-off prevention
Instead of a simple locking mechanism, a full locking mechanism is adopted for cable connectors.

Adoption of cable ties
Cables are bound and fixed to avoid contact with conductive components inside the inverter in case of strong vibrations.

Improved environmental resistance Measures against dust, dirt, and corrosion

Using the inverter in a dusty environment may cause faults such as a short circuit. The inverter with circuit board coating (conforming to IEC60721-3-3 3C2/3S2) ensures reliability even in poor environments. Furthermore, an inverter with plated conductors is also available.
