REV A NOV 

1979 

Power  Source 

This  product  is  i ntended to  operate  in  a  power  module 

connected to a power source that will not apply morethan 

250 volts rms between the supply conductors or between 

either supply conductor and ground. A protective ground 

connection  by  way  of  the  grounding  conductor  in  the 
power cord  is essential for safe operation. 

Groundi ng the  Product 

This product is grounded through the grounding conduc­
tor  of  the power  module power cord.  To avoid  electrical 
shock, plug the power cord into a  properly wired  recep­
tacle  before  connecting  to  the  product  input  or  output 
terminals.  A  protective  ground  connection  by way ofthe 

grounding  conductor  in  the  power  cord  is  essential  for 

safe operation. 

Danger  Arising  From  loss  of Ground 

Upon  loss  of  the  protecti ve-ground  connection,  all 

accessible conductive  parts  ( i ncluding  knobs  and  con� 
trois  that  may  appear  to  be  insulated)  can  render  an 
electric shock. 

Use the Proper Power Module  Power  Cord 

Use only the power cord and connector specified for your 

product. 

Use only a  power cord that  is i n  good condition.
