Module Terminations 
A junction box as a terminal enclosure is 
equipped for electrical connections.   
VBHNxxxSA11 

and 

VBHNxxxSA11B 

Modules are equipped with MC

TM

 plugs 

as a terminal enclosure. Use these MC

TM

 

plugs  for  electrical  connections

 

(see 

Figure 4.1).   
 
Junction Box and Terminals 

 

Modules  are  equipped  with  one 
junction box containing 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 
junction box (see Figure 4.2). 

 

Each  terminal  is  provided  with 
factory  installed  lead  cables  and  a 
latching  connector  for  series  and 
string connections. Always use these 
connectors  and  do  not  detach  them 
from cables. 

 

Latching connectors  are  type  IV  and 
made  by  Multi-Contact.  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  Multi-Contact  and  can  only  be 
released  with  a  special  tool  also 
made 

by  Multicontact 

(PV-MS). 

Locking  sleeves  are  not  supplied 
with 

modules 

and 

must 

be 

purchased separately. 

 
Conduit 

 

In  applications  where  wire  raceways 
or  conduit  are  used,  follow  the 
applicable 

codes 

for 

outdoor 

installations..  

 

Verify  that  all  fittings  are  properly 
installed  to  protect  wires  against 
damage 

and 

prevent 

moisture 

intrusion.  

 

DIODES 

Bypass Diodes 

 

When  modules  in  series  strings  are 
partially 

shaded, 

it 

may 

cause 

reverse 

voltage 

across 

cells 

or 

modules,  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. 

 

Modules  are  equipped  with  factory 
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.  

 

Contact  your  Panasonic  Authorized 
Representative  for  proper  diode 
type,  if  it  is  necessary  to  add  or 
change 

diodes 

due 

to 

system 

specifications. 

 

MAINTENANCE 

 

Some  maintenance  is  recommended 
to 

maintain 

optimal 

output 

performance of the solar modules.  

 

If the module surface becomes dirty, 
it may reduce output power.  

 

It  is  recommended  to  clean  the 
surface  of  the  module  with  water 
and  a  soft  cloth  or  sponge, twice  or 
more per year.  

 
 
 
 

 

A  mild  non-abrasive  detergent  may 
be applied for persistent dirt.   

 

It  is  also  recommended  to  inspect 
the 

electrical 

and 

mechanical 

connections annually. 

 

If  you  need  electrical  or  mechanical 
inspection  or  maintenance,  it  is 
recommended  to  have  a  licensed 
authorized  professional  carry  out 
the  inspection  or  maintenance  to 
avoid  the  hazards  of  electric  shock 
or injury.
