2 Installation and maintenance SAFETY INSTRUCTIONS Check that the frequency converter is correctly connected to earth. Do not pull out the mains or motor contacts or other power connections when the frequency converter is connected to the power supply grid. Protect the user from mains voltage. Protect the motor against overload in accordance with national and local regulations. The leakage currents to earth exceed 3.5 ma, see the Design guide on the enclosed CD. The [Off/Reset] button is not an isolator switch. It does not disconnect the frequency converter from the mains. WARNING! Warning high voltage The frequency converter is subject to highly dangerous voltages when it is connected to the mains. Incorrect installation of the motor or frequency converter can lead to material damage, serious personal injury or death. Follow the instructions in this manual as well as local and national provisions and safety regulations. Voltage (V) WARNING! Discharge time! Frequency converters have DC bus capacitors that can hold a charge even after the mains voltage has been disconnected. Prevent electrical hazards by disconnecting the mains voltage, disconnecting permanent magnet motors and DC bus supplies, including battery backup, UPS and DC bus connections for other frequency converters. Wait until the capacitors have fully discharged before carrying out maintenance or repairs. Read more about the discharge waiting times in the table below. Starting to service or repair the unit immediately after cutting the power supply, without waiting for the specified period, can lead to death or serious personal injury. Output range (kw) Minimum waiting time (min) 3 x 200 0,25 3.7 4 3 x 200 5.5 45 15 3 x 400 0,37 7.5 4 3 x 400 11 90 15 WARNING! Installation at heights For installation at height, contact FläktGroup regarding PELV. TAKE CARE! Residual current device: This product can cause a direct current in the protective earth conductor. When using a residual current device as additional protection, use only a type B residual current device (delayed) on the input side of this product. See also Danfoss application note for the MN90G RCD. The protective earthing of the frequency converter and the use of RCDs must always follow national and local regulations. TAKE CARE! IT system (3x230VAC) When installing the FC101 on an isolated system (IT system, 3x230VAC) set parameter 14-50 to [0] Off. Press [Main Menu] twice. Navigate using the [ ] [ ] and [OK] buttons until parameter 14 50 is displayed (select 14 **, then 14 5* and lastly 14 50). Set this parameter to [0] Off.
Installation and maintenance 3 For 0.25 11kW the RFI switch must be opened by removing the screw (1) on the side of the frequency converter before energising it. See figure beside.

6 Installation and maintenance BASIC CONFIGURATION FOR ASYNCHRONOUS MACHINES (FLÄKTGROUP STANDARD) When the frequency converter is energized for the first time the language can be selected. Obviously this can be changed later. After the configuration guide (FC101 Wizard) is started for 0...10VDC control by pressing [OK] again. If you intend instead to use the internal PID regulator, press [Back] and continue to the next page in the quick guide. Step Parameter Description TF FF 6-15** T53 High Ref./Feedb.

Press [Menu] until the indicator in the display points to Quick menu. Start the configuration guide (FC101 Wizard) by pressing [OK]. Danfoss factory reset Press [Menu] until the arrow points to Main menu. Navigate using the [ ] [ ] buttons and [OK] until the 14-22 parameter is displayed (select 14-**, then 14-2* and lastly 14-22). Set this parameter to 2 and then switch off the mains voltage. When the frequency converter is re-energised the parameters will have returned to their factory settings and alarm 080 is generated. Press [Off/Reset] to acknowledge this.
