If you have added a UPS unit or changed the number of UPS units connected, change this setting
to match the number of UPS units actually connected. If a UPS unit stops during operation for
some reason so that the number of operating UPS units does not match the setting, the message
“
Total Unit# Err
” appears in the UPS status display on the LCD panel.
After you perform the operation in §3.22 “Resetting Values of Settings”, this setting returns to
1
.
In this case, check the number of UPS units in the system and then change the setting again.
