[. . . ] Relay RY11 can be connected to an external indicator device to display or sound an alarm whenever the inverter AC output is lost. The normally open (N. O. ) and normally closed (N. C. ) contacts are available to accommodate the various generator auto-start circuits. Relay Terminal Block Connections to the GSM are accomplished by the nine position, spring clamp, terminal block with quick connect levers. All relay contacts (N. O. , COM and N. C. ) are available at this connector, which accepts wire sizes from #28 AWG to #14 AWG. No tools are required to secure the wires as the spring clamp holds the wires securely in place. Ground Stud A ground screw is provided in the GSM to provide a safety ground path when hazardous voltages are connected to the relays. Connect this screw to a grounded conductor whenever high voltages (i. e. , above 90 volts) are connected to the relays. NOTE: No hazardous voltages are supplied from the inverter to power or control the relays; however, some generator control circuits may use a high voltage in their starting/control circuits or 120 V could be used for an external error indicator. Fuses Each relays common (COM) contact is protected with a 6. 3 amp (5 mm x 20 mm) 250 VAC fuse which will open if excess current is drawn through the relay contacts. Always replace this fuse with the same type and rating. Type GDC (Bussman) or 218 (Littlefuse) is recommended. NOTE: These fuses can be replaced with lower amperage fuses to also protect the connected circuitry, if desired. Refer to the generators specifications for the correct size fuse. To connect the generator wires to the terminal block Lift the appropriate lever for the relay contact. Insert the wire (stripped back 1/4 inch) into the terminal block. Snap the lever down to secure the wire. Please refer to the generator section of the inverters operation manual for additional information. NOTE: Due to the various wiring schemes used by different manufacturers, detailed wiring instructions can not be given in this manual. Please refer to the generator manufacturers documentation for wiring details. CAUTION: DO NOT WIRE THE RELAYS DIRECTLY TO A HIGHAMPERAGE DEVICE, SUCH AS A STARTER MOTOR. THESE RELAYS ARE DESIGNED TO INTERFACE WITH THE GENERATORS AUTO-START CIRCUIT (LOW-CURRENT SIGNALS) ONLY. CONNECTION TO A HIGH-CURRENT DEVICE WILL OPEN THE FUSE IN THE COMMON LINE AND Possibly DAMAGE THE RELAY. [. . . ] Replace fuse, troubleshoot cause of overcurrent. Recheck generator autostart wiring and correct. Inverter is in CHG (charge only) mode. Blue LED lights, green and yellow LEDs do not light. Green and yellow LEDs light but the generator does not start. [. . . ]
