    1 How to Read this Instruction Manual Instruction Manual This Instruction Manual will introduce all aspects of your VLT AQUA Drive. Available literature for VLT AQUA Drive: The Instruction Manual MG.20.MX.YY provides the necessary information for getting the drive up and running.

  • Page 7: Safety

    Installation at High Altitudes At altitudes higher than 6,600 feet [2 km], please contact Danfoss regarding PELV. Warning against Unintended Start 1. The motor can be brought to a stop by means of digital commands, bus commands, references or a local stop while the adjustable frequency drive is connected to line power.

  • Page 8: General Warning

    Also make sure that other voltage inputs have been disconnected, (linkage of DC intermediate circuit), as well as the motor connection for kinetic backup. Before touching any potentially live parts of the VLT AQUA Drive FC 200, wait at least the minimum time as follows: 200–240 V, [0.25–3.7 kW]: wait at least 4 minutes.

  • Page 9: Avoid Unintended Start

    To avoid an unintended start, always activate the [OFF] key before changing parameters. • Unless terminal 37 is turned off, an electronic fault, temporary overload, a fault in the line power supply or lost motor connection may cause a stopped motor to start. ® MG.20.M5.22 - VLT is a registered Danfoss trademark...

    The system consists of a submersible pump controlled by a Danfoss VLT AQUA Drive and a pressure transmitter. The transmitter gives a 4-20 mA feedback signal to the VLT AQUA Drive, which keeps a constant pressure by controlling the speed of the pump. To design a drive for a submersible pump application, there are a few important issues to take into consideration.
