8.1.2 Start-up procedure after maintenance shut down.
NOTE !
UPS system has been turned OFF following the maintenance shut down procedure
and the load is still powered by the maintenance switches Q2.
The load must be transferred back to the UPS system.
Open the front door and make sure that:
a) The safety screens are fixed in their position.
b) The switches Q1 and Q4 are OFF (0) and the external battery circuit breaker or battery fuses are
open. The switch Q2 must be closed.
c) The electronic power supply and the control panel are ON. LEDs 2, 8, 9, “alarm” and “service
check” are ON. The LCD panel (main screen) must indicate the status “load off”.
FOR THE SINGLE VERSION PERFORM THE FOLLOWING OPERATIONS
1. If not already supplied (separate mains inputs), switch-ON the mains power to the rectifier input.
2. Close the input switch Q4.
LED 1 must be lighted and LED 3 (inside rectifier symbol) must blink.
The rectifier starts up automatically, supplying the DC circuit, and charging the DC capacitors.
After some seconds, the contactor K3 closes (the green LED 1 - K3 ON on “P1 - Power Interface” lights
up, see Fig. 4.8.2-1).
The LED 3 (inside rectifier symbol) stops blinking and stay ON, indicating that the DC link has reached
the floating voltage.
3. Battery coupling to DC link.
Close the external battery circuit breaker or battery fuses, after checking the right polarity.
The battery is now connected to the DC link.
LED 4b should be lit indicating battery charge.
The buzzer switch OFF and LED “alarm” is OFF.
4. Close the output switch Q1.
The load is now supplied by the mains through both the automatic and manual bypass.
The LCD panel (main screen) must indicate the status “LOAD ON BYPASS”.
LED 2, 7,8 and 9 is ON and "service check" is OFF.
(In case the "load off" has been previously activated, a reset is needed to enable the bypass).
5. Now open the maintenance switch Q2.
LED 9 is OFF.
The load is now supplied only through the electronic bypass.
The control panel should now indicate a normal situation (No alarms).
LED 1, 2, 3, 4b, 7 and 8 are ON.
LED 4a, 5, 6 and 9 are OFF.
LED “Service check” is OFF.
6. Inverter start.
Press the key "I" on the control panel.
The inverter will start up.
LED 5 (inside inverter symbol) blinks.
In a short time, when the inverter voltage is confirmed, the LED stops blinking and stays continuously
lit. The load will be automatically transferred from mains to inverter.
LEDs 1, 2, 3, 4b, 5, 6 and 8 are now lit. LEDs 4a, 7 and 9 are OFF.
The LCD panel must display the main screen, indicating the status “LOAD ON INVERTER” and the
value of the battery reserve.
