Installation and connections
Installation must only be carried out by qualified personnel who must provide a
suitable fastening system, including suitable mechanical supports to make the
installation safe, considering the stresses to which it may be subjected due to
wind, atmospheric agents etc.
As regards electrical connections, refer to the figures; use a cable with double
insulation (see the table of recommended connection cables); the cable chosen
must be suitable for the type of installation.
The positive terminal of the panel "
+
" must be connected to the terminal "
+
" of
B71/PBX (terminal
12
for
PAN1
; terminal
14
for
PAN2
); the terminal "
-
" of the
panel must be connected to the terminal "
-
" of B71/PBX (terminal
11
for
PAN1
;
terminal
13
for
PAN2
).
Verify the correct polarity at the ends of the connection cables before connecting
to B71/PBX; the wrong connection causes an excessive passage of current and
can damage B71/PBX.
ATTENTION!
Do not connect panels in series; B71/PBX provides for the connection
