SAFETY   CONSIDERATIONS  

The   unit   should   only   be   operated   by   a   competent   person   who   is   completely  
familiar   with   the   operation   and   specification   of   the   load   bank. 

 

The   equipment   is   designed   for   AC   operation   @   50Hz   only   and   therefore    must   not  
be   used   on   DC   loads   such   as   batteries. 

 

Operators   must   ensure   that   interconnecting   cables   are   correctly   rated   to   carry   the  
required   load   current   and   adequately   insulated   to   prevent   the   possibility   of   electric  
shock. 

 

When   in   use   the   load   bank   should   be   cordoned   off   using   safety   barriers. 

 

The   load   bank   should   only   be   operated   in   an   area   with   adequate   ventilation. 

 

Care   should   be   taken   as   the   exhaust   air   outlet   will   be   hot. 

 

Cables   must   be   positioned   away   from   the   air   exhaust 

 

During   operation   the   load   bank   should   not   be   covered   or   positioned   to   restrict   air  
flow 

 

Caution   –   some   metal   surfaces   will   be   hot   during   operation 

 

At   the   end   of   any   test   the   fan   should   be   kept   running   for   10   minutes   without   load  
to   remove   the   residual   heat   from   the   load   bank   case. 

 

 
CONNECTION   PROCEDURE  

 

● Ensure   the   power   source   to   be   tested   is   compatible   with   the   load   bank  

operating   voltage   and   frequency.  

● Ensure   the   power   source   is   de-energised.  

● Do   not   attempt   to   operate   the   load   bank   above   the   maximum   operating  

voltage   or   frequency  

● Check   all   panel   mounted   control   switches   are   in   the     OFF     position.  

● Connect   the   hand   held   controller   to   the   load   bank  

● Ensure   the   neutral   and   earth   are   connected   correctly   to   the   power   source  

● Ensure   the   neutral   and   earth   are   connected   correctly  

 

● Ensure   the   power   cables   are   correctly   connected   to   the   power   source   

● Connect   powerline   connectors   to   the   load   bank
