3 Approvals and Certications

3.1 Regulatory/Compliance Approvals

This section provides a brief description of the various approvals and certications that are on Danfoss VLT® drives. Not all approvals

are on all drives.

N O T I C E

IMPOSED LIMITATIONS ON THE OUTPUT FREQUENCY

From software version X.XX onwards, the output frequency of the drive is limited to 590 Hz due to export control regulations.

Software versions 6.xx also limit the maximum output frequency to 590 Hz, but these versions cannot be ashed, that is, neither

downgraded nor upgraded.

3.2 Typical Product Approvals and Certications for VLT® Drives

The VLT AQUA Drive product series complies with a wide scope of required standards and directives. Information on the specic

product certications can be found on the product nameplate.

3.2.1 CE Mark

The drive complies with relevant directives and their related standards for the extended Single Market in the European Economic

Area.

2

For China RoHS, contact Danfoss application support to get the certicate.

3

Radio Equipment Directive is only required for interfaces supporting wireless communication.

3.2.1.1 Low Voltage Directive

The aim of the Low Voltage Directive is to protect persons, domestic animals and property against dangers caused by the electrical

equipment, when operating electrical equipment that is installed and maintained correctly, in its intended application. The directive

applies to all electrical equipment in the 50–1000 V AC and the 75–1500 V DC voltage ranges.

3.2.1.2 EMC Directive

The purpose of the EMC (electromagnetic compatibility) Directive is to reduce electromagnetic interference and enhance immunity

of electrical equipment and installations. The basic protection requirement of the EMC Directive states that devices that generate

electromagnetic interference (EMI), or whose operation could be aected by EMI, must be designed to limit the generation of elec-

tromagnetic interference and shall have a suitable degree of immunity to EMI when properly installed, maintained, and used as

Approvals and Certications

VLT® AQUA Drive FC 202

Design Guide

intended. Electrical equipment devices used alone or as part of a system must bear the CE mark. Systems do not require the CE

mark, but must comply with the basic protection requirements of the EMC Directive.

3.2.1.3 Machinery Directive

The aim of the Machinery Directive is to ensure personal safety and avoid property damage to mechanical equipment used in its

intended application. The Machinery Directive applies to a machine consisting of an aggregate of interconnected components or

devices of which at least 1 is capable of mechanical movement. Drives with an integrated functional safety function must comply

with the Machinery Directive. Drives without a functional safety function do not fall under the Machinery Directive. If a drive is inte-

grated into a machinery system, Danfoss can provide information on safety aspects relating to the drive. When drives are used in

machines with at least 1 moving part, the machine manufacturer must provide a declaration stating compliance with all relevant

statutes and safety measures.

3.2.1.4 ErP Directive

The ErP Directive is the European Ecodesign Directive for energy-related products. The directive sets ecodesign requirements for

energy-related products, including drives, and aims at reducing the energy consumption and environmental impact of products by

establishing minimum energy-eciency standards.

3.2.1.5 ATEX Directive

Illustration 1: ATEX Logo

3.2.1.6 RoHS Directive

The Restriction of Hazardous Substances (RoHS) Directive is an EU directive that restricts the use of hazardous materials in the man-

ufacturing of electronic and electrical products. Read more on www.danfoss.com.

3.2.1.7 Radio Equipment Directive

Devices that emit or receive radio waves as part of radio communication are required to comply with the Radio Equipment Direc-

tive. The drive itself does not contain a radio device, and hence compliance to the directive is not relevant. However, user interfaces

containing active radio devices, such as the integrated control panel with wireless communication capabilities, comply with the di-

rective.

3.2.2 REACH Directive

Compliance with European REACH regulation on Registration, Evaluation, Authorization, and Restriction of Chemicals. Read more

on www.danfoss.com.

3.2.3 UL Listing

3.2.4 CSA/cUL

3.3 Export Control Regulation

AC drives can be subject to regional and/or national export control regulations. Both the EU and USA have regulations for so-called

dual-use products (products for both military and non-military use), which currently includes AC drives with a capacity to operate

600–2000 Hz. These products can still be sold, but it requires a set of measures, for example a license, or an end-user statement.

An ECCN number is used to classify all AC drives that are subject to export control regulations. The ECCN number is provided in the

documentation accompanying the AC drive. If the AC drive is re-exported, it is the responsibility of the exporter to ensure compli-

ance with the relevant export control regulations.

For further information, contact Danfoss Drives Global or the local sales oce.

3.4 Enclosure Protection Rating

The VLT® drive series are available in various enclosure protection ratings to accommodate the needs of the application. Enclosure

protection ratings are provided based on 2 international standards:

UL type validates that the enclosures meet NEMA (National Electrical Manufacturers Association) standards. The construction

and testing requirements for enclosures are provided in NEMA Standards Publication 250-2003 and UL 50, 11

th

edition.

IP (Ingress Protection) ratings outlined by the IEC (International Electrotechnical Commission) in the rest of the world.

The standard Danfoss VLT® drive series are available in various enclosure protections to meet the requirements of IP00 (Chassis),

IP20 (Protected chassis), IP21 (NEMA Type 1), or IP54 (NEMA Type 12). In this manual, NEMA Type is written as Type, for example,

IP21/Type 1.

4 Product Family Overview

4.1 VLT® Drives

Danfoss oers 3 types of AC drives in dierent-sized enclosures for a wide range of applications, with power ratings from 0.25–1200

kW (0.34–1350 hp).

Standalone drives (frequency converters)

The Danfoss standalone drives are so robust that they can be mounted outside of cabinets virtually anywhere, even right beside the

motor. Equipped for the toughest of environment, they suit any application.

More uncompromising features:

Enclosure sizes with protection ratings up to IP66/UL Type 4X.

Full EMC compliance according to international standards.

Ruggedized and coated PCBs.

Wide temperature range, operating from -25 to +55 °C (-13 to 131 °F).

Motor cable lengths up to 150 m (492 ft) for shielded cables and 300 m (984 ft) for unshielded cables.

Enclosed drives

Danfoss enclosed drives are designed with the installer and operator in mind to save time on installation, commissioning, and main-

tenance. The enclosed drives are designed for full access from the front. After opening the cabinet door, all components can be

reached without removing the drive, even when mounted side by side. Several cooling options, including back-channel cooling,

provide optimum adaption to the installation location and application.

More time-saving features:

An intuitive user interface with an award-winning local control panel (LCP) and common control platform that streamlines start-

up and operating procedures.

Robust design and advanced controls make Danfoss drives virtually maintenance free.

System modules

The compact design of the system modules makes them easy to t even in small spaces. Integrated lters, input fuses, options, and

accessories provide extra capabilities and protection without increasing the enclosure size.

More space-saving features:

Built-in DC-link reactors for harmonic suppression eliminate the need for higher loss external AC line reactors.

Optional built-in RFI lters are available throughout the power range.

Regen terminals are available within the standard enclosures (for enclosure sizes D, E, and F).

In addition to the many valuable features that the Danfoss drives oers as standard, there are several other control, monitoring,

and power options available in pre-engineered factory congurations.

For more details on the enclosure types, the modularity, and the applications, see the product-specic Selection Guides on

www.danfoss.com.

4.2 Product Overview of the VLT® AQUA Drive FC 202

The VLT AQUA DriveFC 202 is a drive for controlling AC induction motors, permanent magnet synchronous motors, and synchro-

nous reluctance motors (SynRM motors). As other Danfoss AC drives, the VLT AQUA Drive is motor independent, meaning that the

drive can be connected to any brand of motor, thus providing great exibility when designing an installation.

The FC 202 is designed for water and wastewater applications. The integrated SmartStart wizard and the quick menu Water and

Pumps guide the user through the commissioning process. The range of standard and optional features includes:

Cascade control

Cascade for multi-pump operation with run-time balancing of pump running hours. Basic cascade control built in as stand-

ard with a capacity of up to 3 pumps. Systems with multiple variable-speed pumps require the VLT® Extended Cascade Con-

troller MCO 101, the VLT® Advanced Cascade Controller MCO 102, or the license code option for Digital Cascade via built-in

MODBUS.

Multi-master cascade control

Redundant cascade system with up to 8 masters per system. If the primary master stops working, a back-up master auto-

matically takes over.

Dry-run detection

This feature prevents damage to the pumps by avoiding dry-running and pump overheat.
