Troubleshooting
Basic Troubleshooting
Table 6 is organized in order of common symptoms, with a series of possible causes. Each
shows possible troubleshooting remedies, including system display checks where appropriate.
These instructions are for use by qualified personnel who meet all local and governmental code
requirements for licensing and training for the installation of electrical power systems with AC
and DC voltage up to 600 volts.
Figure 12 AC Test Points
WAR
NING: Shock Hazard
During an error shutdown, the inverter’s output terminals are not live. However, if
the inverter recovers from a shutdown, the terminals will become live without notice.
Several error shutdowns can be recovered automatically, including
Low Battery V
,
High Battery V
, and
Over Temperature
. See page 52.
NOTE:
In Table 6, “System display only” usually indicates that a MATE3-class device is
required to perform the step. It cannot be performed without the system display.

at the attachment screw for
each AC conductor.
