
Low Battery Cut-In
: The recovery point from
Low Battery Cut-Out
. When the DC voltage rises
above this point for 10 minutes, the error will clear and the inverter will resume functioning. This item
is adjustable.
 Connecting an AC source for the inverter to charge the batteries will also clear a low battery error.

Output Voltage
: The AC output voltage can be adjusted. Along with small changes, this allows the
inverter to be used for different nominal voltages such as 100 Vac and 127 Vac.
IMPORTANT:
The output voltage can be adjusted to a different nominal value for a particular region.
Making this change will not affect the default input voltage range accepted by the inverter
from an AC source. The input range must be adjusted manually. These changes should
be made at the same time. (See
AC Source Acceptance
on page 26.)

The inverter is also controlled by a high battery cut-out limit. If the DC voltage rises above this limit,
the inverter i
mmediately stops functioning and gives a
High Battery V
error. This func
tion is intended
to prote
ct the inverter’s output and loads. Continuing to invert on a high DC voltage may produc
e a
distorte
d waveform. Note that the inverter’s high battery cut-out does not alleviate the high bat
tery
state. The ca
use is an external condition which could damage the in
verter.
 The high battery cut-out voltages for each model are shown in Table 18 on page 63. This voltage
is not a ch
angeable set po
int.
 If the voltage drops below this point, the inverter automatically recovers.
 This is one of the errors on page 52. It appears as an event on a MATE3-class system display.
The low battery and high battery functions are summarized in Table 18 on page 63.

UTION: Equipment Damage
Setting the inverter’s output frequency to deliver 50 Hz to 60-Hz loads, or setting it to deliver
60 Hz to 50-Hz loads, could damage sensitive devices. Make certain the inverter’s output
frequency matches the installation.
The inverter’s output can operate at a frequency of either 60 or 50 Hertz. This output frequency
(and the AC acceptance frequency) can be changed with the
Operating Frequency
menu item.
This requires high-level access. Due to the possibility of damage, access to this setting has
been restricted by placing it in the
Grid Interface Protection
menu.
The installer password must be changed from the default in order to get access to this menu.
Once this password has been changed, the
Grid Interface Protection
menu can only be
accessed by using the installer password. This password can be changed in the system
display.
See page 17 for more information on this selection in
Grid Interface Protection
. See the menu
tables, which begin on page 66, for the location of the
Operating Frequency
menu item.
