NITIAL OPERATIONS
▪
Visual connection check
Check that all the connections have been made following the indications given in the "Electrical connections"
paragraph to the letter.
Check that all the isolating switches are open.
▪
Batter fuse holder closure
close the switch/fuse of the battery rack (first check the polarity of the connections);
Note: The equipment is protected against battery inversion (for further details see "Battery anti-inversion
device")
CAUTION: In the event that the batteries are connected to the battery terminals with the polarity
inverted, this device will protect the CPS by interrupting the battery connections.
As the fuses are being closed, a small electric arc caused by the capacitors inside the CPS may
be generated. This is quite normal and not the result of malfunctions and/or breakage.
▪
CPS power supply
Close the protection devices upstream from the CPS.
▪
Closing the input, output and bypass isolating switches
Close the input isolating switch (SWIN), output isolating switch (SWOUT) and bypass isolating switch (SWBY).
The maintenance isolating switch (SWMB) must remain open.
S
WITCHING ON FOR THE FIRST TIME
➢ Wait for a few seconds after closing the SWIN. Check that the display
comes on and that the CPS is set to "STAND-BY" mode.
➢ Check that no error messages appear indicating an incorrect cyclical direction of the phases. If this error appears,
proceed as follows:
▪
check which of the input or bypass connections the error refers to (only if the connection with separate bypass is
present)
▪
open all the battery box isolating switches and fuse holders.
▪
wait until the CPS has switched off completely, checking that the display is off
▪
open all the protection devices upstream from the CPS
▪
remove the switch cover panel
▪
correct the position of the cables relative to the terminal block signalled so that the cyclical direction of the phases
is respected
▪
reposition the switch cover panel
▪ repeat the power-on operations, including the "Preliminary operations"
