STANDARDS
VBHNxxxSA and VBHNxxxKA series com-
ply with the requirements of UL1703.
FIRE CLASS OF PRODUCT

The fire rating of this module is valid
only when mounted in the manner
specified in the mechanical mount-
ing instructions.

The models in this instructions are
suitable to maintain the System Fire
Class Rating A when used with a
Listed mounting system and a roof
covering that have been rated as a
Class A System when installed on a
steep slope roof and/or a low slope
roof with "Type 2" modules.
JUNCTION BOX AND TERMINALS

Modules equipped with one junc-
tion box contain terminals for both
positive and negative polarity, and
bypass diodes.

Each terminal is dedicated to one
polarity (with the polarity symbols
engraved onto the body of the junc-
tion box) (see Figure 2).

Each terminal is provided with facto-
ry installed lead cables and a latch-
ing connector for series and string
connections. Always use these con-
nectors and do not detach them
from cables.

The PV module comes pre-wired.
Each module has two #12 AWG type
PV-wire stranded sunlight resistant
output cables each terminated with
connectors. The positive (+) terminal
has a male connector while the neg-
ative (-) terminal has a female con-
nector. The module wiring is solely
for series connections only, i.e. male
(+) to female (-) interconnections.
When making field wiring connec-
tions to the preattached connectors
use only approved connectors from
Table.2.

Latching connectors are type IV and
made by STAUBLI ELECTRICAL CON-
NECTORS AG. Supplied connectors
listed by UL.

In order to comply with NEC 2008, a
locking sleeve needs to be used with
all connectors that are exposed.

The locking sleeve (PV-SSH4) is
made by STAUBLI and can only be
released with a special tool also
made by STAUBLI (PV-MS). Locking
sleeves are not supplied with mod-
ules and must be purchased sepa-
rately.
BYPASS DIODE

When the modules in series strings
are shaded partially, it may cause
reverse voltage across cells or mod-
ules, because the current from other
cells in the same series is forced to
flow through the shaded area. This
may cause undesirable heating to
occur.

The use of a diode to bypass the
shaded area can minimize both
heating and array current reduction.

All modules are equipped with fac-
tory installed bypass diodes. The
factory installed diodes provide
proper circuit protection for the
systems within the specified system
voltage, so that you do not need
any other additional bypass diodes.

Specifications of bypass diode for
VBHNxxxSA and VBHNxxxKA mod-
ules are as follows; Type: Number of
bypass diode: 4 diodes, Number of
series cells per bypass diode: 24
cells / diode (See Figure 3).
