Note: The following descriptions relate to operation of the UPS using the keys
below the display screen. Operation can also be carried out using the touchscreen
capability, juts type in the appropriate files or text.
5.1. START UP
5.1.1. CONTROL BEFORE START UP
Ensure that all the connections have been made correctly and are sufficiently tight,
respecting the labeling of the device and the instructions in chapter 4. “Installation
and wiring of the unit”.
Check that the UPS switches and the battery cabinet or cabinets are turned off
(position “Off”).
Be sure that all the loads are turned “Off”.
5.1.2. START UP PROCEDURE
It is very important to operate “start-up” in the established order and to
considering the following instructions.
If you start up a UPS in a parallel system, the written procedures apply to both
UPS devices. You can use the procedure described below step by step for the first
UPS and then for the 2nd UPS until you see the message “Close battery switch!”
Now you can close both battery switches. It is irrelevant which UPS starts first.
If the UPS connects to an external battery cabinet, set the fuse holder switch of
the battery cabinet (Q8) to “On”.
If the power supply to the UPS has a general switch, set the general switch of the
header board to “On”.
Turn the input switch (Q1a) to “On” position. The display of the Control Panel (PC)
will be turned on automatically.
If the following alarm message appears on the Control Panel Display ...
PHASE REVERSE INPUT POWER
… and an audible alarm sounds, the UPS cannot be started because of incorrect
input phase sequence. Disconnect the input switch (Q1a) and the general cut-off
of the header board, swap the phases of the input terminals of the UPS according
to the labeling and repeat the start-up process described previously.
