Error Indicator Wiring
If an error indicator is used (light, buzzer, bell, etc.), connect the wires to
the RY11 relay contacts. Depending on the error indicator used, either the
N.O. or N.C. contacts can be used. Typically, the N.C. and COM contacts are
used to complete a circuit, turning on a light, buzzer, etc. The N.C. contacts
are held open until an error condition is detected (or the AC output is OFF);
at which time the N.C. contact will close completing the circuit and activating
the external device.

For convenience, add an external OFF switch in line with the alarm
device. This allows turning off the alarm until the inverters output is restored.
NOTE: The diagrams shown here are intended as an example of
how the relays operate an external alarm device. Actual alarm types
may operate differently from these diagrams. Refer to the owners
manual for specific alarm wiring. Do not exceed the voltage or
amperage ratings of the relay and fuse.
