Installation recomendations
for transformers
Safety
A low voltaje installation must be carried out whilst
taking the necessary precautions in order to respect the
safety principals in all the parts. The wires from the pri-
mary from the secondary not cross.
Low voltage installations must be carried out taking
into account a number of safety principles. Mains and
LV leads must be kept separated otherwise it must be
assured that the isolation of the cables is higher than
4KV.
Maintenance operations must be performed by quali-

entire given product instructions and the regulations cur-
rently in force.
Mains power
Mains voltage and mains frequency must be within
the normal range of operation.
Make sure that the neutral is always connected in
3-phase supplies. In case of neutral interruption the in-
put voltage of the single loads can be near to 400V that
results in high risk of failure.
Single-phase loads should be distributed evenly be-
tween the phases.
Temperature
Transformers must be installed far enough from heat
sources to allow correct dissipation of its own heating.
Protection against humidity must be assured.

transformer housing. Continuous operation of the trans-
former above Tc leads to a reduction of its lifetime ac-
cordingly.
Never keep the transformers covered by thermal insula-
tion elements like stone wool blankets or others.
Wiring
Leads with suitable isolation, length, and cross-section
must be used.
Considering the same power, the current at 12V is 20
times higher than that at 230V.
