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 RY7 is used for generator RUN/GLOWSTOP functions.
Relay RY8 is used for the generator START function.
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. In no case,
should this fuse be replaced with one of a higher amperage.
