 (e.V.s.)

When voltage rises to extreme levels because 
of a lost neutral line or an accidental connection 
to 208 or 240 VAC, Furman’s Extreme Voltage 

Shutdown kicks in, automatically powering down 
all  equipment  quickly  and  safely  to  prevent 

damage  from  occurring.  An  indicator  LED  will 

then illuminate, alerting you to the situation until 
the over voltage condition is corrected by turning 

the unit off and then back on.

Please  read  and  observe  all  of  the  safety  and 

operating  instructions  before  the  IT-20  II  is 
operated.  Retain  these  instructions  for  future 
reference.

Do  not  disassemble  or  modify  in  any  way. 

No user-serviceable parts inside 

Keep  away  from  moisture  and  avoid 
excessive humidity

Do  not  allow  liquids  or  foreign  objects  to 
enter the unit. Household lighting equipment 
may not be connected to the IT-20 II because 

its  sockets  are  not  designed  for  use  with 

symmetrical power and may present a shock 
hazard.  We  recommend  that  only  audio, 
video  and  computer  processing  equipment 

be connected to the IT-20 II

The  IT-20  II  should  be  serviced  by  qualified 

service personnel when:

The  power  supply  cord  or  plug  has  been 
frayed or cut

Objects have fallen or liquid has spilled into 

the unit

The  IT-20  II  has  been  exposed  to  rain  or 
other moisture

The  IT-20  II  does  not  appear  to  operate 

normally,  or  exhibits  a  marked  change  in 

performance

The  IT-20  II  has  been  dropped,  or  the 
enclosure damaged

The  IT-20  II  requires  that  a  safety  ground  be 
present  for  proper  operation.  Any  attempt  to 
operate  the  IT-20  II  without  a  safety  ground 

is  considered  improper  operation  and  will 

invalidate the warranty.

The  power  source  to  which  the  IT-20  II  is 

connected  should  be  adequate  for  use  at  7 
amps.  Typical  household  outlets  will  have  a 
current capacity of at least 10 - 15 amps.
