Options Board (Figures 4 & 5)
The Options Board is an installed circuit card that allows
for the connection of Arc Fault, Ground Fault, and Rapid
Shutdown System sensors (toroids).
Figure 4
shows the location of the Option Board
installed in the
Hawke’s Bay
.
Figure 5
shows the Options Board, sub-boards, and
connection receptacles.
Bypass Switch & TB1 (Figure 5)
For Rapid Shutdown System operations, the Hawke’s
Bay via the Options Board can be configured to accept an external switch to initiate Rapid
Shutdown.
On the lower right corner of the Options
Board is a Bypass Switch (CON4). To
allow an external switch to control RSS,
move the jumper to the JP2 position and
connect the wires from the external
switch into the RS Switch (TB1). TB1 is
Normally Closed (NC); NC means no Rapid
Shutdown. When the input to TB1
becomes open, Rapid Shutdown is
initiated. For internal MPPT initiation of
Rapid Shutdown, move the jumper to the
JP1 position.
