This chapter provides detailed instructions on how to turn the power supply on and off, as well
as switching between the modes described in the previous chapters.
All control keys and the LCD panel used to switch between the modes described below are
described in detail in Chapter 5.
During the following procedures, acoustic signaling may occur. This alarm can be silenced at any
time by pressing "Mute" on the LCD panel.
4.4 Procedures to start the power supply
4.4.1 Start up the UPS from full shutdown
Use the following procedure when starting the power supply from total shutdown.
Attention
When the following procedure is performed, voltage appears on the output
terminals of the power supply. If the power supply is connected to receivers,
check that the power supply is safe. If the receivers are not ready to connect the
power supply, make sure they are securely isolated from the UPS output.
The startup procedure for a dual power supply is as follows:
1. Close the UPS output switch (Q4) - for the HS 505 UPS only. For the HS 205 and HS 305 power
supplies that have only a mechanical bypass disconnect switch, use an external power switch in the
UPS power distribution board.
Close the bypass input switch (Q2) and then the rectifier (Q1) - for HS 505 only. The switching
sequence is very important. For power supplies HS 205 and HS 305, equipped with a mechanical
bypass switch only, use external power connectors in the UPS power switchboard.
The rectifier LED flashes during the start up of the rectifier. The LEDs on the UPS should look like the
following table:
LED State
Rec diode Green flashing
Battery diode Red
Bypass diode Turn off
Inv diode Turn off
Output diode Turn off
State diode Red
Running takes about 30 seconds, after which time the rectifier diode glows green. After the start-up
and testing process, the bypass and start-up of the inverter are switched on. The LEDs on the UPS
should look like the following table:
LED State
Rec diode Green
Battery diode Red
Bypass diode Green
Inv diode Green flashing
Output diode Green
State diode Red
When the inverter is started, the inverter outputs the power to the inverter output (normal operation).
After switching to the inverter's power supply, the Bypass LED goes out and the inverter's LED goes
green as follows:
