Wiring the SB6000U
Communication Wiring
5-14
SMA America
SB6000U-13:SE2506
5. Pull the DC wires from the DC disconnect through the conduit into the interior of the
SB6000U
.
6. Connect the positive DC wire to the terminal labeled DC+ in the Sunny Boy.
7. Connect the negative DC wire to the terminal labeled DC– in the Sunny Boy.
Note:
The
SB6000U
has provisions for either one or two PV
strings. The positive and negative terminal blocks each have
two positions, so two pairs of DC-input wires can be
connected in parallel.
CAUTION: Avoid using wire nuts to join any wires together
or to make any connections anywhere in the PV system.
Wire nuts are a frequent cause of unreliable connections,
resistive connections, and ground faults.
8. Connect the positive and negative DC wires to the appropriate terminals in the DC
disconnect enclosure.
9. Connect the DC equipment ground wire to the terminal labeled PE in the SB6000U.
10. Torque all wires to 18 in-lb.
11. Verify that all connections are correctly wired and properly torqued.
Communication Wiring
Various data-communication options are available for the Sunny Boy 6000U. These
options are provided in the form of accessory Piggy-Back modules that can be installed
and connected either at the time the inverter is installed or at any time thereafter. These
modules are not included with the SB6000U. Please contact SMA America for
information. Refer to the instructions included with the communication module for
installation procedures.
The following subsections provide instructions for connecting the various communication
cables between a
SB6000U
with a communication module and a personal computer
(PC). The connection of a
SB6000U
to a Sunny Boy Control or a Sunny Beam PV plant
monitoring unit is shown in those respective manuals.
RS-232 Communication
RS-232 is a communication standard for bidirectional transmission of data between a
Sunny Boy and a PC. Only one Sunny Boy can be connected with an RS-232 serial cable
to a PC.
