(PVI-STRINGCOMB (-S, -MC, -S-MC) - Rev:1.0)
9.3.16 Connection of the other PVI-STRINGCOMB(-S)
If there are other PVI-STRINGCOMB(-S) devices, carry out the same
procedures described above before going on to the next step.
9.3.17 Closing the DC switch (only version –S)
If the devices are of the PVI-STRINGCOMB-S type, close the
switch/isolator in order to send voltage to the inverter.
9.3.18 Final checks
(A) Check that the cable glands are tightened.
(B) Make sure that any unused cable glands are plugged off with the
caps provided.
(C) If the PVI-STRINGCOMB(-S) on which you are working is the
last of the serial chain, make sure that the termination is
correctly inserted (Ref. §9.3.2). Otherwise, make sure that the
termination is disconnected.
(D) Take note of the Serial Number (S/N) given on the label affixed to
the external surface (Figure 1-1).
9.3.19 Closing the cover
Place the cover on the base and tighten all the 8 screws using a
suitable flat blade screwdriver of the correct size for plastic screws, to
avoid damaging it. In order to close the cover correctly, it is advisable
to do the screws loosely at first and tighten them when the cover is
perfectly placed.
9.3.20 Assigning the FIELD NUMBER
At this point, it is necessary to assign a number to the PVI-
STRINGCOMB(-S) devices connected to the system.
For this, a Computer containing the monitoring software is required
(Ref. §11), using the direct connection of Figure 7-3 as indicated in
point B.
In general, follow the instructions given in (Chapter §12).
To make the S/N association of the PVI-STRINGCOMB(-S) with the
chosen identity number (Field Number) more evident, the number
should be written on the outside of the container.
