SAFETY PRECAUTIONS
1.

 All the precautions, in particular the safety ones, must be read with special attention, as

they provide important information.

2.1 - PRIMARY POWER SUPPLY FROM MAINS

 

-

The mains voltage is sufficiently high to involve a risk of electrocution: never install or 
connect this product when its power cord is plugged in.

 

-

Before powering up, make sure that all the connections have been made correctly and 
the voltage of your mains corresponds to the voltage shown on the rating plate on the 
unit, if not, please contact your RCF dealer.

 

-

The metallic parts of the unit are earthed by means of the power cord. 
An apparatus with CLASS I construction shall be connected to a mains socket outlet 
with a protective earthing connection.

 

-

Protect the power cord from damage. Make sure it is positioned in a way that it 
cannot be stepped on or crushed by objects.

 

-

To prevent the risk of electric shock, never open this product: there are no parts inside 
that the user needs to access.

2.2 - 24 V dc SECONDARY POWER SUPPLY BY BATTERIES

 

-

The apparatus operating voltage is 24 V dc, therefore it is necessary to connect in 
series several batteries having a lower nominal voltage, example: 2 x 12 V.

 

-

Always use rechargeable batteries, which need to be chosen according to the 
maximum possible load.

 

-

Verify the polarity of batteries is correct.

 

-

Do NOT short-circuit batteries (i.e. connecting the 2 opposite poles together with 
metallic wires).

 

-

Throw empty batteries away according to your country laws about ecology and 
environment protection.

3.

Make sure that no objects or liquids can get into this product, as this may cause a short

circuit. 
This apparatus shall not be exposed to dripping or splashing. No objects filled with liquid 
(such as vases) and no naked sources (such as lit candles) should be placed on this 
apparatus.

4.

Never attempt to carry out any operations, modifications or repairs that are not expressly 

described in this manual. 
Contact your authorized service centre or qualified personnel should any of the following 
occur:

 

-

The product does not function (or functions in an anomalous way).

 

-

The power cord has been damaged.

 

-

Objects or liquids are inside the product.

 

-

The product has been subject to a heavy impact.
