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).
