Product Description:

Offered by Danfoss, the 131F8849 automation drive can trigger radio interference in a residential surrounding. This drive is not recommended for applications that demand an output frequency higher than 590 Hz. The product’s lifting must be undertaken with the dedicated eye bolts. This device should have sufficient space above and below it for cable access and the flow of air. The unit’s mains cables, control wires, and motor cables are to be run separately. Its switching frequency must be set appropriately when it is used with a sine-wave filter. This drive’s fastening bolts must be used as high-frequency connections to the rear plate for a low impedance.

The product’s main supply is isolated from the ground by a RFI switch. This device’s U, V, and W terminals are connected to the U, V, and W phases of the related motor. The unit’s connection with the LCL filter is done with a shielded cable. Its terminals can have up to 1099 VDC voltage based on the supply voltage. This drive supports an external power supply connection on the power card if it is supplied by a DC. The product comes equipped with an internal overcurrent protection. This device’s control terminal connectors can be unplugged. The unit-associated motor must have insulated bearings on the non-drive end. Its terminals for the control cables are situated under the local control panel on its front.

This automation drive may cause 50/60 Hz ground loops as a result of noise from mains supply cables in rare cases. The product’s analog input terminals are configured using switches. This device can control several motors with a parallel connection. The unit doesn’t ensure motor overload protection with its electronic thermal relay. Its display shows the INITIALIZING message when the startup is delayed.
