MECHANICAL INSTALLATION
It is recommended to construct a cable duct below the middle part of the cabinet. The duct width may
not exceed 300 mm and the contact surface of the floor must resist the cabinet weight that lies on the
legs.
Clearances
The SD700SP VFD must be installed in vertical position, and firmly fastened through the dedicated
anchorages placed in the rear part of the drive that avoid any movement.
If the equipment is installed inside a cabinet, ensure that the hot air expelled from the VFD is evacuated
outside. This hot air can be aspirated again so the drive may suffer from overheating. To ensure a suitable
cooling, avoid the recirculation of air and keep the minimum clearance distances indicated below.
Minimum clearances for frames 1 to 4. SD700SP without solar kit.
Minimum clearances for frames 5 to 8. SD700SP without solar kit.
Cooling
The heat sources inside the equipment correspond with the inverter bridge (IGBTs), rectifier bridge, the
input filter and the output dV/dt filter. SD700SP series present an overall efficiency higher than 98% at
rated power, so the heat dissipation approximately corresponds to 2% of the input power.
The drive is designed with three independent cooling areas.
