4.3 Procedure For Switching The UPS Into a Maintenance Bypass From Normal Operation
This procedure should be followed when turning from inverter output to maintenance bypass. This procedure
can be used in giving temporality mains voltage to the system during the maintenance of the UPS or in case
of failure.
1.
Press on the UP or DOWN button when there is “COMMAND MENU” message on the front panel of the
UPS. Then press “ENTER” button.
2.
Press on the UP or DOWN button when there is “ENTER <BYPASS>” message on the front panel of the
UPS. Then press “ENTER” button for 3 seconds. L4 static by-pass led lit and L6 inverter led off. Now your
load is feeding from the Static By-pass.
3.
Take out the lock from the S3 (maintenance bypass) switch.
4.
Turn on (into “1” position) the S3 (maintenance bypass) switch.
5.
F1-F2-F3-S1 (rectifier input fuses-inverter input),
S4 (UPS output)
S2 (static by-pass),
BATT(+) and BATT(-) Open this fuses and the switches. Into “0” (OFF) position
WARNING!!! Inside the UPS the following points will be on operation:
* By-pass AC input mains terminals
* Maintenance by-pass switch
* Static by-pass switch
* UPS output terminals
Now you’re load is completely feeding from the maintenance by-pass and the
UPS is closed.
WARNING!!! During the maintenance or static by-pass the connected loads at the UPS output
can not being protected against the mains failure.
4.4 Procedure For Switching The UPS ON From a Maintenance By-Pass Power Down
Condition
1.
While the S3 switch in closed position ”1” (ON) ;
turn on (into “1” position) the F1-F2-F3-S1 (rectifier input fuses- inverter input), S2 (static bypass) and S4
(UPS output) Switch.
2.
Turn on (into “1” position) the S1 (inverter input) switch.
3.
When “MAINT SWITCH ON!” message appears on the front panel, turn off (into “0” position) the S3
(maintenance by-pass) switch. By this way the load will be fed from the static by-pass.
4.
See “STATUS NORMAL!” message on the front panel and the green inverter led lit.
5.
Turn on the BATT.(+) and BATT.(-) fuses into “1” (ON) position. Now the UPS system is in normal
operation. You can start-up your PC, printer etc.
