GROUNDING INSTRUCTIONS 

 

IMPORTANCE: 
DISCONNECT  POWER  BEFORE  SERVICING,  RECONNECT  ALL 
GROUNDING DEVICES. 

 

All  mechanical  parts  of  this  appliance  capable  of  conducting  electricity  are 
grounded.  In the event of an electrical short circuit, grounding reduces the risk of 
electric  shock.    This  appliance  is  equipped  with  a  cord  having  a  grounding  wire 
with  a  ground  plug.    The  plug  must  be  plugged  into  an  outlet  that  is  properly 
installed and grounded. 
 

WARNING: 
IMPROPER  USE  OF  THE  GROUNDING  PLUG  MAY  RESULT  IN 
ELECTRICAL SHOCK. 

 

If grounding wires, screws, straps, clips, nuts or washers used to complete a path 
to  ground  are  removed  for  service,  they  must  be  returned  to  their  original 
positions and properly fastened. 
 

GROUNDING SPECIFICATION: 

Leakage current: 

 

0.75mA max. 

Ground path resistance: 

0.1ohm max.
