S OLAR PUMP APPLICATIONThe installation instructions in this chapter are intended only for VACON® 100 X Drives with addi-tional solar pump application.10.1 Danger10.2 Warning10.3 DC Fuse selectionThe fuses on the DC-Input of the inverter must have the following characteristics:It is recommended to use gPV fuses, which are developed for solar application, in order to protectcables and panels against reverse overcurrent, when multiple strings are connected in parallel.See chapter 10.4. for recommended gPV fuse manufacturer.The photovoltaic fuses have to meet the IEC 60269-6 or the UL 2579 standard.The terminals are live when the VACON® 100 X Drive is connected to a photovoltaic system.Photovoltaic cells generate DC voltage even at low intensity of sunlight.Wait 30 seconds until the drive is discharged, before switching between AC and DC supply(photovoltaic system) and vice versa.Do not remove the EMC screws in the solar pump application. IT (impedance-grounded) ACsupply network is not allowed in the solar pump application.Table 51. Fuse characteristicsFuse type Min. Voltage ratingDC current 1000 V
