Place the inverter horizontally. When placing the inverter on the floor, put foam or paper under the inverter to protect its shell. 3.7. Installing HYD 3K~6K-EP Step 1 Determine the positions for drilling holes, ensure the hole positions are level, then mark the hole positions using a marker pen, use the hammer drill to drill holes on the wall(Aperture10 mm). When drilling, keep the impact drill perpendicular to the wall and drill slightly deeper than the length of the expansion pipe. After drilling, please check whether the hole position is suitable with the back plate. If the error is too large, please reposition the hole. Step 2 Slowly hammer the expansion screw into the drilled hole. Step 3 Position the back plate well, place the shrapnel and flat pad, and fix the back plate with hexagon nut. Step 4 Hang the inverter on the back plate and lock the inverter and the back plate with M6 hex screw. Step 5 You can secure the inverter to the rear panel and protect if from stealing by installing an anti-theft lock (this action is optional).

Electrical Connections Before performing electrical connections, ensure that the DC switch is OFF. Since the stored electrical charge remains in a capacitor after the DC switch is turned OFF. So it's necessary to wait for at least 5 minutes for the capacitor to be electrically discharged. HYD 3K~6K-EP inverter is intended to be used in PV system with battery storage. If not used as intended, the protection provided by the equipment may be impaired. Attention Danger Installation and maintenance of inverter, must be operated by professional electrical engineer. Wear rubber gloves and protective clothing (protective glasses and boots) when working on high voltage/high current systems such as inverter and battery systems. PV modules generate electric energy when exposed to sunlight and can create an electrical shock hazard. Therefore, before connecting DC input power cable, cover PV modules using opaque clot. For HYD 3K~6K-EP,open-circuit voltage(Voc) of module arrays connected in series must be 580V.

Troubleshooting This section contains information and procedures for solving possible problems with the inverter. This section help users to identify the inverter fault. Please read the following procedures carefully: Check the warning, fault messages or fault codes shown on the inverter screen, record all the fault information. If there is no fault information shown on the screen, check whether the following requirements are met: - Is the inverter mounted in a clean, dry place with good ventilation? - Is the DC switch turned ON? - Are the cables adequately sized and short enough? - Are the input and output connections and wiring in good condition? - Are the configuration settings correct for the particular installation? - Are the display panel and the communication cables properly connected and undamaged? Follow the steps below to view recorded problems: Press "Back" to enter the main menu in the normal interface. In the interface screen select "Event List", then press "OK" to enter events. Earth Fault Alarm This inverter complies with IEC 62109-2 clause 13.9 for earth fault alarm monitoring. If an Earth Fault Alarm occurs, the fault will be displayed on the LCD screen,the red light will be on,and the fault can be found in the history of the fault. For the machine installed with WiFi/GPRS, the alarm information can be seen on the corresponding monitoring website, and can also be received by the APP on the mobile phone.

Inverter will automatically return to normal operating status when the electric grid's back to normal. If the alarm occurs frequently, check whether the grid voltage/frequency is within the acceptable range. If yes, please check the AC circuit breaker and AC wiring of the inverter. If the grid voltage/frequency is NOT within the acceptable range and AC wiring is correct, but the alarm occurs repeatedly, contact technical support to change the grid over-voltage, under-voltage, over-frequency, under-frequency protection points after obtaining approval from the local electrical grid operator.
