8.  Safety Declaration 

 

 

Do not expose the DPA

four

 to extreme temperatures, direct sunlight, humidity, or dust, which could 

cause fire or electrical shock hazard. 

 

Keep away water or other liquids from the DPA

four

, otherwise fire or electrical shock may result. 

 

This  unit  is  equipped  with  a  single  pole  disconnect  device  (fuse)  in  the  phase  (live)  wire.  If  an  un-polarised 

mains connection is used, the receptacle the unit is connected to must be equipped with a two pole disconnect device 
(fuse) of appropriate rating!

 

 

Connect  the  power  cord  only  to  an  AC  outlet  of  the  type  stated  in  this  Owner's  Manual  or  as 

marked on the unit, otherwise fire and electrical shock hazard results. 

 

When disconnecting the power cord from an AC outlet always grasp the plug. Never pull the cord. 

A damaged power cord is a potential risk of fire and electrical shock hazard. 

 

Avoid touching power plugs with wet hands. Doing so is a potential electrical shock hazard. 

 

Observe  the  correct  polarity  when  operating  the  DPA

four

  from  a  DC  power  source.  Reversed 

polarity may cause damage to the unit or the batteries. 

 

Avoid placing heavy objects on power cords. A damaged power cord is a fire and electrical shock 

hazard. 

 

Do not cut, scratch, bend, twist, pull, or heat the power cord. A damaged power cord is a fire and 

electrical shock hazard. Ask your ATEÏS dealer for replacement. 

 

Immediately  turn  off  the  unit,  remove  the  power  cord  from  the  AC  outlet  and  consult  your  ATEÏS 

dealer in any of the following circumstances: 

 

Smoke, odour, or noise coming from the unit. 

 

Foreign objects or liquids falling inside the DPA

four

 

The unit has been dropped or the shell is damaged. 

 

The power cord is damaged. 

If you continue using the DPA

four

, fire and electrical shock may result. 

 

Do not drop or insert metallic objects or flammable materials into the unit as this may result in fire 

and electrical shock. 

 

Do not remove the DPA

four

 's cover, as there are exposed parts inside carrying high voltages that 

may cause an electrical shock. Contact your ATEÏS dealer if internal inspection, maintenance, or repair is 
necessary. 

 

Do  not  try  to  make  any  modifications  to  the  DPA

four

.  This  is  a  potential  fire  and  electrical  shock 

hazard. 

 

Slots  and  openings  in  the  unit  are  provided  for  ventilation.  To  ensure  reliable  operation  and  to 

prevent overheating of the unit, these openings must not be blocked or covered! 

 

Leave  enough  space  above  and  below  the  unit  to  provide  good  ventilation  of  the  DPA

four

.  If  the 

airflow is not adequate, the DPA

four

 will overheat and may cause a fire.
