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: Electrical Connection
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 17: Connection Instructions For Ac Output Cables
5�2�2 Connection instructions for AC Output Cables ATTENTION! An independent three-phase circuit breaker must be installed on the AC side of each inverter. Do not install one circuit breaker for multiple inverters! ATTENTION! Install a model B leakage curren protection switch with no less than 600 mA current. - Page 18 Fig. 10: Securing the PE cable NOTE The PE wire must be well grounded to ensure that impedance between Neutral and Earth wire be less than 10 Ω. Connection of AC Output Cable In the lower part of the front of the inverter there is an covered AC wiring area. 1.
