VLT® 2800 Quick Guide - Danfoss

1 1 Quick WarningsHigh Voltage Warning:The voltage of the frequency converter is dangerous whenever it is connected tomains. Incorrect installation of the motor or frequency converter may cause damageto the equipment, serious injury or death. Consequently, it is essential to complywith the instructions in this manual as well as local and national rules and :Touching the electrical parts may be fatal - even after the equipment has been dis-connected from make sure that other voltage inputs have been discon-nected (linkage of DC intermediate circuit). Be aware that there may be high voltageon the DC link even when the LEDs are turned off. Before touching any potentiallylive parts of the frequency converter, wait at least 4 Current:The earth leakage current from the frequency converter exceeds mA. Accordingto IEC 61800-5-1 a reinforced Protective Earth connection must be ensured bymeans of a min. 10mm Cu or an addtional PE wire - with the same cable crosssection as the Mains wiring - must be terminated increase safety, install an RCDR esidual Current Device:This product can cause a DC current in the protective conductor.

2 Where a residualcurrent device (RCD) is used for extra protection, only an RCD of Type B (time de-layed) shall be used on the supply side of this product. See also Danfoss ApplicationNote on RCD, earthing of the frequency converter and the use of RCDs must alwaysfollow national and local Thermal Protection:Protection against Motor overload is not included in the factory setting. If this func-tion is required, set par. 128 Motor Thermal Protection to data value ETR trip or datavalue ETR warning. For the North American market: The ETR functions provideoverload protection of the motor, class 20, in accordance with in high altitudes:For altitudes above 2 km, please contact Danfoss regarding PELV. VLT 2800 Quick Guide1 Quick - VLT is a registered Danfoss trademark1 Safety Instructions The frequency converter must be disconnected from the mains if repair work is to becarried out. Check that the mains supply has been disconnected and the prescribed timehas passed before removing motor and mains plugs.

3 Make sure the frequency converter is properly connected to earth. Protect users against supply voltage. Protect the motor against overloading according to national and local regulations. The earth leakage current exceeds mA. For ELCB types, please see application The [STOP/RESET] key on the control panel of the frequency converter does not dis-connect the equipment from mains and is thus not to be used as a safety switch. Note that the frequency converter has more voltage inputs than L1, L2 and L3 when DCbus terminals are used. Check that all voltage inputs are disconnected and that the pre-scribed time has passed before repair work is commenced. Warning against unintended motor can be brought to a stop by means of digital commands, bus commands,references or a local stop, while the frequency converter is connected to mains. If per-sonal safety considerations make it necessary to ensure that no unintended start oc-curs, these stop functions are not parameters are being changed, the motor may start.

4 Consequently, the stop key[STOP/RESET] must always be activated, following which data can be motor that has been stopped may start if faults occur in the electronics of the frequencyconverter, or if a temporary overload or a fault in the supply mains or the motor con-nection ceases. Use on Isolated MainsSee section RFI Switch in the operating instructions regarding use on isolated is important to follow the recommendations regarding installation on IT-mains, since sufficientprotection of the complete installation must be observed.
