ATTENTION:

 

 

Read the manual carefully before starting to use the control unit. Keep the instructions for future reference 

 
 
Do not open the device, touching any internal components can cause electric shock. Contact with voltage over 50 
Volts can be fatal. To reduce the risk of electric shock, do not dismantle the back of the device for any reason.  
Moreover its opening would void the warranty. 
 

Before connecting the device to the power supply, make sure that all the connections are correct. 

Always disconnect 

the unit from the supply before any cabling modification. 

 

Any work on the equipment must be entrusted to a qualified engineer. 

 

Failure  to  comply  with  these  instructions  can  cause  damages,  fires  or  electric  shock,  and  possible  serious 
injuries! 

 

 

POWER SUPPLY

 

The  NT539  has  UNIVERSAL  power  supply,  i.e.  it  can  be  supplied  by  24  to  240  Vac-Vdc,  irrespectively  of  polarity  in  Vdc. 
Before using it, make sure the power cable is not damaged, knotted or pinched. Do not tamper with the power cable. Never 
disconnect  the  unit  by  pulling  the  cable,  avoid  touching  the  pins.  Do  not  carry  out  any  connecting/disconnecting  with  wet 
hands. To disconnect the device, do not use objects such as levers. Immediately disconnect the device if you smell burning 
or see any smoke: contact technical service. 

 

LIQUIDS

 

Do not expose the equipment to splashes or drops, do not position it in places with humidity exceeding 90% and never touch 
with wet or humid hands. If any liquid penetrates the control unit, disconnect it immediately and contact technical service. 
 

 

CLEANING

 

Disconnect the power cable before cleaning the control unit, use a dry cloth to dust it, without any solvent or detergents, and 
compressed air. 

 

OBJECTS

 

Never  insert  any  objects  into  the  cracks  of  the  control  unit.  If  this  happens,  disconnect  the  control  unit  and  contact  an 
engineer. 

 

USE RESERVED TO QUALIFIED PERSONNEL

 

The purchased goods are a sophisticated electronic device that is totally unsuitable to be used by non-qualified personnel. 
Any work must be carried out by a specialist engineer. 

 

ACCESSORIES

 

The use of non-original accessories or spare parts can damage the unit and endanger users' safety.  In the event of faults, 
contact technical service.

 

 

 

LOCATION

 

Install  the  control  unit  indoors,  in  a  place  protected  from  water  splashes  and  sun  rays.  Do  not  place  near  heat  sources 
exceeding the parameters stated in this manual. Position on a stable surface, far from any possible vibrations. Position the 
unit as far as possible from any intense magnetic fields. 

 

REPAIRS

 

Do not open the control unit. For any fault, always use qualified personnel. The opening of the control unit and/or the removal 
of the series identifying label entails the automatic forfeiture of the warranty. The Warranty seal is applied to all devices, any 
attempt to open the unit would break the seal and cause the consequent automatic forfeiture of the warranty.
