1  Check  the  wiring;  positive  connected  to 
positive (red cables), negative connected to 
negative (black cables). 
2  When all wiring is OK, place the DC fuse(s) 
to connect the batteries to the ChargeMaster 
Plus. 
WARNING! 
When  placing  this  fuse,  a  spark 
might  occur,  caused  by  the 
capacitors  used  in  the 
ChargeMaster  Plus.  This  is 
particularly  dangerous  in  places 
with insufficient ventilation. Due to 
the  gassing  of  the  batteries,  an 
explosion can occur. Avoid having 
flammable materials close by. 
3  Switch on the AC power supply. 
Note: when new, the ChargeMaster Plus will 
not start charging batteries before activated 
with the ON/OFF button. See step 6. 
4  Check the DIP switches.  
See chapter DIP switch settings on page 16. 
5  Check  and  adjust  the  settings  of  the 
ChargeMaster  Plus  with  MasterAdjust 
(MasterBus  network)  or  with  the  CZone 
Configuration Tool (CZone network). 
See chapter SETTINGS on page 16.

needs, press and hold the ON/OFF button for 
3  seconds  to  switch  the  charger  on  and
