Page 13: Installation
Installation CAUTION! The inverter is a heavy device! To prevent personal injury or device damage, arange two people to move the ■ inverter and handle with care. 4�1 Package contents When the inverter is delivered check and report any damage on the box that may affect its contents. -
Page 14: Selecting The Installation Location
4�2 Selecting the installation location DANGER! Fatal fire or explosion hazard! The inverter is an electrical device with heat generation and the possibility of sparking. Install the inverter in an environment that is free of flammable gases and fluids ■ Never install the inverter near combustible materials. -
Page 15: Mounting The Inverter
4�3 Mounting the inverter NOTE The SHT series inverters should be mounted on a mounting system or substruc- ture. A mounting system is not included. All commercially available mounting sys- tems are suitable which guarantee permissible mounting. The inverter is attached to the wall or to a mounting system using a mounting plate. The mounting plate and the mounting material are included in the scope of delivery. - Page 16 2. Drill the holes. Insert the dowels, position the bracket and insert the screws to lock it. Alternatively, you can fix the supplied mounting plate of the inverter to a mounting system with the corresponding screws. 3. Mount the inverter on the monting bracket and tighten the inverter with rear panel using screws as shown in the following figure: 4.

5�2�1 Integrated RCD and RCM The SHT Series inverters are equipped with integrated RCD (Residual Current Device) and RCM (Residual Current Monitor) according to VDE 0126-1-1. The sensor measures the residual current and compares it to the pre-set value, disconnecting automatically the inverter from the AC grid by means of the integrated RCD in case the value exceeds it. - Page 18 ATTENTION! Install a model B leakage current protection switch with no less than 600 mA current. Do not share neutral wire when B leakage current protection switch is installed or else a power grid trip may occur. AC output cables requirements For AC power cables outdoor multi copper-cores cables are recommended.
- Page 19 Heat shrink tubing Fig. 11: Connecting the OT terminals to the AC cable 4. Loosen the four screws of the AC cover on the inverter and remove the cover. 5. Push the AC cable through the opening in the cable cover from behind. The cable must be pulled through so that the conductors can be connected to the termination strip of the inverter.
- Page 20 Fig. 13: Tightening the wiring board 8. Connect the external Protective Earth cable. Secure the cable tighten the screw. Fig. 14: Connecting the external Protective Earth cable CAUTION! The external Protective Earth connection cannot substitute the one present in the AC connector used to connect the inverter to the grid. Make sure that both cables are present and connected, otherwise warranty may be void in case of failure of the electrical connections.
