[. . . ] This is a safety feature which allows the generator to be serviced without it unexpectedly starting due to an inverter GEN-START command. GENERATOR START Switch The GENERATOR START switch enables the relays by providing the operating voltage to the relay coils RY7 and RY8. When the relays are enabled, they will respond to the control signals provided by the inverter. When the switch is in the RELAYS DISABLED position, the inverter control signals have no effect on relay operation (i. e. , the COM and N. C. This switch does not affect the operation of the LEDs which continue to light whenever the inverter sends a CLOSE CONTACT command to the relays. INVERTER ERROR Switch The INVERTER ERROR switch provides a simple way to test an externally connected alarm. Once the alarm is tested, this switch should be switched to the RELAY READY position. GENERATOR Switch (RY7 and RY8) INVERTER ERROR Switch (RY 11) Figure 3 Switches ©2001 Xantrex Technology Inc. 3 1. 0 INTRODUCTION Internal Components The Generator Start Module (GSM) is designed to control generators equipped with two- or three-wire, electronic, automatic start operation (not all generators are supported) and provides the following features. Relays There are three 12 VDC relays, rated at 10 amps/250 VAC; 8 amps/ 30 VDC (for resistive loads), with gold contacts increasing the low-end signal range. 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. NOTE: These fuses can be replaced with lower amperage fuses to also protect the connected circuitry, if desired. To connect the generator wires to the terminal block Lift the appropriate lever for the relay contact. 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.
