OPERATIVE PROCEDURES
Before any attempt to put the system online it is mandatory to check the power supply and connections
(PHASE, NEUTRAL, BATTERY).
Refer to “MPX Installation manual”.
SYSTEM ON
Operations to be performed in order to Switch On the MPX.
The MPX can be switched to “Normal Operation” in two ways:
A. SYSTEM ON: DIRECT COMMAND
Switch on the Mains and Bypass Input lines.
The system will activate in “Stand-By” mode (The Leds on PSU1 and PSU2 - if present - will be lit).
Verify the Mains and Bypass input voltages on the “System Status” page.
Verify that no anomalies are present on the system status page (except the alarm “Batteries not present”).
Verify that all the configured PMs are ready (the red led “ALARM” blinks slowly).
Verify that all the configured BM are ready (the green led “BYPASS READY” is lit fixed).
From the “Command Panel” page, slide “System Off/On” from “O” to “I” to start the System.
Confirm “System ON” command.
This command will automatically Start Up the System with the following sequence:
1. PMs Pre-charge
2. PMs Inverters Synchronise
3. Transfer the load onto the Static Bypass Line
4. Transfer the load onto the Inverter Output
The “Awaiting Start Up” process will take approximately one minute.
Verify that no anomalies are present on the “System Status” page.
Verify that the measurements of inverter voltages are correct, and that the system status is “Load on Inverter”.
Connect the batteries to the system.
Check the battery status and verify the measurements.
From the “Command Panel” page slide the “Battery Test” from “O” to “I” to execute the test.
Verify that the Alarm “Batteries Not Present” is no longer present anymore.
From this point the system is in normal operation.
