According to IEC a reinforced Protective Earth connection must be ensured by means of: a min. YY must be followed! The information and instructions of the Operating Instructions are not sufficient for a correct and safe use of the Safe Stop functionality! Page 8: It Mains 2. The software version number can be seen from parameter Page 9 Equipment containing electrical components must not be disposed of together with domestic waste.

It must be separately collected with electrical and electronic waste according to local and currently valid leg- islation. Page Introduction Below is an example of an identification label. This label is situated on the frequency converter and shows the type and options fitted to the unit. See table 2. Illustration 3. Page Mechanical Installation The packaging for these enclosures contains, as shown: Accessories bag s , documentation and the unit.

Depending on options fitted there may be one or two bags and one or more booklets. Page How To Install The frequency converter can be mounted side by side for all IP rating units and requires mm free space above and below for cooling. With regard to ambient temperature ratings, please see Special Conditions. Mechanical installation Illustration 4. Illustration 4. Page 18 Illustration 4. A2 and A3 units have back-plate as standard.

For correct cable dimensions please see the section General Specifications at the back of this manual. Page How To Connect Motor - Foreword Furthermore, the terminal screw must be retightened after two days due to the softness of the aluminium.

It is crucial to ensure the connection makes a gas tight joint, otherwise the aluminium surface will oxidize again. Page 33 Illustration 5. Page 34 Illustration 5. Please ensure that the outer insulation of the motor cable is removed under the EMC clamp.

Page 35 The following section describes how to terminate control wires and how to access them. For an explanation of the function, programming and wiring of the control terminals, please see chapter, How to programme the frequency converter. Page 36 Remove front-cover to access control terminals.

When replacing the front-cover, please ensure proper fastening by applying a torque of 2 Nm. Page 38 7 regarding these. Page 39 Step 8: Press the [Off] button to stop the motor again. Remove mains power from the frequency converter before changing motor wires. This will avoid ground current interference among groups. For example, it avoids switching on digital inputs disturbing analog inputs. Page 41 Please note that the switches may be covered by an option, if fitted.

This number along with the description of the alarm will assist troubleshooting. If contacting Danfoss Service, make sure to mention number and alarm description. To design a drive for a submersible pump application, there are a few important issues to take into consideration. Filled Set Point Par.

Page 51 Menu keys The menu keys are divided into functions.

The keys below the display and indicator lamps are used for parameter set-up, including choice of display indication during normal operation. Page 52 [Info] provides detailed information when needed. The key can be [1] or [0] via par. Page 56 Certain parameters can be changed step by step or infinitely variably. This applies to par. The parameters are changed both as a group of numeric data values and as numeric data values infinitely variably.

If more than one frequency converter is connected to a master, use par- allel connections. Illustration 7.
