Connections notes
•
Connection to the mains:
Columns can be powered by 19V AC to 13.8V DC, but is preferable by the last.
•
Connection:
The connection between the transformer and the 230 V ~ must be made with
cables whose section is approximately 1.5 mm ². It is strongly recommended
to use an upstream fuse 1 A delayed. The cable that carries power from the
transformer to MANA will be as short as possible, should come with shield
grounded. The two wires must be connected to terminals 1-2 of the "power
connector”. The transformer used must have the following characteristics:
Primary voltage = 230 V~
Secondary voltage = 18 o 19 V~ 1 A
Secondary voltage = 24 V~ 6 A
Minimum power = 160 VA
NB
: Use only safety transformers with a certificate, such as 60950. Must
be given good grounding of the housing processor. Connecting the
transformer to 230 V ~ must be made through a device that has the
following characteristics:
1.
Bipolar with minimum distance between the contacts of 3mm
2. Provided in the fixed installation
3.
Easily accessible
In any case, you should carefully follow the requirements contained in
the related law of fixed devices permanently connected to the mains as
the Law 46/90 and CEI 64-8.
In the case of mains very disturbed to add an effective filter 230V 1 A
