WARNING! 
All  electrical  systems  (AC  and 
DC)  must  be  disconnected  from 
any  power  source  during  the 
entire installation! 
CAUTION! 
Too-thin  cables  and/or  loose 
connections  can  cause 
dangerous  overheating  of  the 
cables  and/or  terminals. 
Therefore, tighten all connections 
well,  in  order  to  limit  transition 
resistance as far as possible. Use 
cables of the correct size. 
CAUTION! 
Short  circuiting  or  reversing 
polarity  may  lead  to  serious 
damage  to  the  batteries,  the 
ChargeMaster  Plus,  the  cabling 
and/or  the  terminal  connections. 
Fuses between the batteries and 
the  ChargeMaster  Plus  cannot 
prevent  damage  caused  by 
reversed polarity. The damage as 
a  result  of  reverse  polarity  is 
detectable by the service depart-
ment  and  is  not  covered  by  the 
warranty.
