Cancel Output Shutdown

This command cancels any pending or current UPS output shutdown. This

command requires the USER SECURITY CODE.

Recover Output Shutdown Only When AC Line Restored (xxx)

xxx=“Yes” or “No”, (Default value is “Yes”)

This command determines when the CFR restores output power after a

output shutdown. If this option is set to “Yes”, the UPS restores output when
the input AC line is restored. Note that the output is guaranteed to be off for
the

“Output Shutdown Duration” period. During this period, the CFR will not

activate the output, even if AC line is restored. However, if this option is set
to “No”, then the CFR activates its output as soon as the

“Output Shutdown

Duration” has expired. Thus, the CFR may even restore output in the
inverter mode. Changing this option requires the USER SECURITY CODE.

Set Output Shutdown Delay (HH:MM:SS= hh:mm:ss)

This command sets the “output shutdown delay” period. After the CFR

receives an output shutdown command, it will wait for this period before
switching off the output.

hh:mm:ss - hh is hours; mm is minutes; ss is seconds. Entering the

seconds is optional, (i.e., HH:MM format is also acceptable). The factory
default setting for this value is 00:00:00 which causes the CFR to immedi-
ately shutdown when a shutdown command is set. If the CFR is set to start
shutdown when delay is set (menu item 501 is set to “Yes”), then it also acts
as a shutdown command, and the count down for shutting down the unit
starts immediately (there is no need to issue a 502 command). This feature
requires the USER SECURITY CODE for activation.

Set Output Shutdown Duration (HH:MM:SS= hh:mm:ss)

This command sets the

“Output Shutdown Duration” which is the

guaranteed down time after an output shutdown.

hh:mm:ss - hh is hours; mm is minutes; ss is seconds. Entering the

seconds is optional, (i.e. HH:MM format is also acceptable). The factory
default setting for this value is 00:00:05 which causes the CFR to remain in
shutdown for a minimum of 5 seconds. The CFR may restore output
immediately when this duration is expired, or may wait for the AC line to be
restored (depending on the setting of menu item 504). This feature requires
the USER SECURITY CODE for activation.

Shut Off Inverter / Save Battery

This feature requires the USER SECURITY CODE and can only be

activated if unit is in LINE FAILURE mode. The inverter can then be shut off
to preserve battery power if its no longer necessary to back up the load.
Upon return of the line voltage, the unit will then resume operation as
normal.

Start-up Inverter From Save Battery

This feature requires the USER SECURITY CODE and can be

activated only if the inverter was shut off from save battery (507). The
inverter then can be restarted to provide power to the load.
