The standalone drives have a protection rating of at least IP21/Type 1. These drives can be mounted both outside and inside in
dusty and damp environments without any further protection.
The enclosed drives have a protection rating of IP20/Chassis and must be built into cabinets for protection against dust and mois-
ture. The enclosed drives are not suitable for outdoor installation.
Both standalone drives and enclosed drives come in dierent enclosure sizes depending on the selected power size, voltage range,
and enclosure protection rating.
For low-power applications from 0.25–90 kW (0.5–125 hp), select between enclosure sizes A, B, C, and D3h.
For high-power applications, select between enclosure sizes D, E, and F, see the specic design guides for drives above 90 kW
(125 hp).
Functionalities
The VLT AQUA Drive oers various customizable functionalities, such as:
power hardware with varying voltage ratings, current ratings, protection ratings, and EMC performance ratings.
control hardware with various control cards with, for example, advanced cascade control card for handling up to 8 pumps in
either mixed pump or master/follower.
added functional extensions, for example eldbusses, for extending the functionalities of the drive, for example, easy PLC inte-
gration.
license packages, including condition-based monitoring and digital Cascade Controller using built-in Modbus in daisy chain
conguration for easy installation.
Troubleshooting and maintenance
Troubleshooting and maintenance of the FC 202 are made easier and more precise with the increased digitalization.
The sensors in the FC 202 record and store real-time information about warnings and alarms. By adding the VLT® Real-time Clock
MCB 117 option, it is possible to have the stored events time and date stamped without mains power, for example, due to mains
power outage.
Regarding maintenance, the FC 202 features functions for preventive maintenance and condition-based maintenance.
The preventive maintenance functions are programmed in the drive and can be used to schedule maintenance alerts based on run-
ning time of the drive.
Using the condition-based monitoring functions turns the drive into a sensor that continuously monitors the condition of the motor
and application. Using the DrivePro® services with the drive, the collected data can be shared with maintenance personnel and oth-
er service providers.
4.3 Advantages of Using AC Drives in Pump and Fan Applications
When comparing with alternative control systems and technologies, a drive is the optimum energy control system for controlling
fan and pump system.
By using an AC drive to control the ow, around 50% of energy savings can be achieved in typical variable-torque-applications, if
the pump speed is reduced by 20%. See an example of the achievable energy reduction in Illustration 6.
