Battery charge cycle (pushbutton #1) (applies to UPS module only)
Pressing this pushbutton begins a battery charging cycle. After the cycle is
complete, the rectifier/battery charger returns to float charge levels on the battery.
The battery charge cycle is not applicable to sealed lead-acid battery installations.
Return to float voltage (pushbutton #2) (applies to UPS module only)
This pushbutton can be used during a battery charge cycle to force the
rectifier/battery charger back to the float voltage level.
Security pushbutton (key)
This pushbutton must be pressed simultaneously with any of the following
three pushbuttons. This helps guard against inadvertent transfer
of the load with interruption.
Inverter desync/sync (pushbutton #3) (applies to SSC only)
Pressing and holding the "security key" while pressing this pushbutton
forces the inverter output to desynchronize or synchronize to the
bypass AC input (mains 2) source.
