Page 5: Packing And Transport
1. Packing and transport The circuit-breaker is shipped in special packing in the open position, with the springs discharged and with the absolute pressure of the pole corresponding to the service value. Each piece of apparatus is protected by a plastic cover to prevent water from infiltrating during the loading and unloading stages and to keep the dust off during storage. -

6. Instructions for operating the circuit-breaker 6.1 Safety indications HD4/... circuit-breakers guarantee a minimum IP3X degree of protection when installed in the following conditions: – fixed version, installed behind a protective metal net – plug-in version, installed in switchgear. In these conditions the operator is totally protected against accidental contact with moving parts. Pay the greatest attention to moving parts if the circuit-breaker is subjected to mechanical operations outside the switchgear or when the protective nets have been removed. - Page 18 6.3.4 Closing operation 6.3.5 Opening operation Make sure that the springs of the operating mechanism are Press the opening pushbutton (3). loaded, as indicated by the yellow signal in the window (7).
