START UP FOR PARALLEL UPS SYSTEM
WARNING: Make sure all requirements and previous inspection have been revised and complied before initiating
start up procedure. If not please do not try to continue with start-up procedure.
1.- Make sure all equipments to be protected and connected to UPS output are in OFF condition.
2.- Check AC input breaker located in UPS rear panels is in OFF position in all UPS of the system.
3.- Power on external main AC input in electrical panel. Set to ON position all external AC input breakers.
4.- If UPS are using external battery packs, set to ON all DC breakers to connect external DC packs to UPS.
5.- For UPS No. 1: Set to "ON" AC input breaker located in rear panel of UPS No. 1. Wait until UPS No.1 completes auto-
checking and Bypass LED lights continuously.
6.- For UPS No. 2: Set to "ON" AC input breaker located in rear panel of UPS No. 2. Wait until UPS No.2 completes auto-
checking and Bypass LED lights continuously.
7.-In case of having 3 UPS in the system, proceed in similar manner with UPS No. 3.
IMPORTANT: AC input breakers activation must be done in one by one and not at same time. First for UPS No. 1, then for
UPS No. 2 and finally for UPS No. 3 (if you have a parallel system with 3 UPS). If AC input breakers are activated all at
same time, warning message "3F" could be activated. If it occurs, reinitiate procedure sequentially. Warning 3F message
must be previously reset according to warning and error section in this manual
8.- When rear panel AC breaker is set to "ON", This UPS recognizes all other UPS previously powered ON in the parallel
system and will get its own parallel identification as PAR 00X, where X is the position according to power on sequence.
PAR 001 for 1st UPS powered on, PAR 002 for 2nd and PAR 003 for 3rd UPS.
This message is only indicated in UPS manufactured after Dec-2011. If UPs is before Dec-2011 continue without waiting
for PAR 00X message.
9.- At this moment all UPS LCDs must turn on to indicate internal circuitry in UPS is been powered.
** If bypass mode is allowed, all UPS will go to bypass mode.
** If bypass mode is not allowed by configuration, all UPS will go to a kind of stand-by mode with
outputs open and powered off waiting until ON command is selected in UPS front panel.
10.- At this moment configuration menu in each UPS LCD must be revised to select desired configuration. It is mandatory
to use same configuration in all configuration parameters for all UPS of the system.
11.- Once configuration has been selected and verified, all UPS can be started up by selecting "ON" push button in front
panel. Please press "ON" push button for each UPS. One long "beep" will be generated. "ON" message will be displayed on
top side of LCD.
12.- All UPS will go to NORMAL Online mode at same time.
13.- Before setting to "ON" all external output breakers please revise AC voltage output on each UPS.
** Please measure AC output voltage using a digital multi-meter and confirm all output voltages are similar. Maximum
acceptable deviation should be 3Vac or lower. Typically 1Vac.
** If difference between output voltage values is higher than 3Vac, we suggest to adjust them by function 15 (for inverter
output L1) and function 16 (for inverter output L2). You can reduce (Sub) or increase (Add) voltage output voltage for
each of 2 inverters in each UPS as required.
14.- If AC output voltages are as expected, please set to "ON" external output breakers for all UPS progressively. Start with
UPS Nº 1, then UPS Nº2, etc. After that, all UPS outputs are connected in parallel.
15. Check to confirm there are no error or alarm messages on LCDs. At this moment all UPS are working in NORMAL
Online mode and connected in parallel.
16.- It is time to power on equipments connected to UPS output. Power on progressively one by one. Check on UPS
LCDs how power output rises meanwhile equipments are powered on.
** Once all output load is connected check power output is below 100%.
** At this moment, UPS parallel system is powering your system in NORMAL Online mode.
