4. disconnect in case of a serious fault The fuse should have a sufficient rating so as not to blow under heavy load conditions Your inverter will normally be the biggest load in your system if this is the case a motor start fuse equal to or slightly higher than the maximum continuos current of the inverter should be used If in any doubt see your supplier or installer CONNECTION OF AC AND DC WIRING IMPORTANT Before making any wiring connections check that the circuit breaker on the front panel is in the OFF position 1 e LEVER DOWN Your electrician should firstly connect the AC wiring via the three terminal rear junction box Carefully observe the correct connections Please refer to the diagram overleaf BROWN ACTIVE red dot top connector GREEN YELLOW EARTH E centre connector BLUE NEUTRAL Bottom connector The lid of the junction box has knockouts to allow conduit entry Make sure this connection is tight and safe Re fit junction box cover NOTE ALL AC WIRING MUST BE CARRIED OUT BY A LICENSED ELECTRICIAN AND MUST CONFORM TO AS3000 WIRING REGULATIONS OR RELEVANT STANDARDS Verify that the circuit breaker on the front panel is in the OFF position LEVER DOWN Now connect the battery cables RED BATTERY POSITIVE BLACK BATTERY NEGATIVE These connections should be tight If using nuts bolts and washers they should be stainless steel At this point re check the connections before proceeding any further
