2.4.2 After the UPS starts up, verify that all three LED indicators on the front 
panel are illuminated.

2.4.3   Turn   on   the   battery   circuit   breaker   (handle   in   the   up   position).   The 
characteristic sound of the main transformer in the UPS may change somewhat 
due to charging of the battery system.

2.4.4 Connect the load(s) to the UPS output.

2.5      Continuous Operation

  

It is recommended that the unit be left on all the time. This will insure that the 
battery remain charged to it full capacity. The unit is designed to operate 24 
hours per day and is not required that it be turned off during the week-ends

2.6      Shut Down Procedure

2.6.1 Disconnect the load from the UPS.

2.6.2 Disconnect the commercial AC source from the UPS.

2.6.3 Press the BATTERY OFF push-button switch on the front panel to turn off 
the UPS.

2.6.4   Turn   off   the   BATTERY   CIRCUIT   BREAKER     (handle   in   the   down 
position) to prevent further discharge of the battery.

2.6.5 If servicing of the UPS or the battery is required, disconnect the battery 
cable at the battery before performing any maintenance.

3.        DESCRIPTION OF OPERATION

3.1

General Operation

Figures 3.1 and 3.2 illustrate the operation of this system.   Please note that 
under normal operation (Figure 3.1), the AC input operates through the inverter 
and is then further regulated and filtered.  The output of the unit is a very clean 
sinewave with an output voltage that is regulated to  3% with an input 
voltage swing of + 10% and -15%.   During this operation, a special inverter 
circuit provides trickle charge to the battery.

During standby operation when the commercial line is not present, the inverter 
is switched totally to the battery which converts the battery’s DC voltage to AC 
and supplies power to the regulator/filter.  The output is then the same as if the 
line   were   present.   Transfer   from   a   charger   to   inverter   is   done   within 
microseconds and no power interruption occurs at the output.
