1.1.4.
Line connection area
TopCon power supplies are operated with 400V / 480V 3~ AC. When
they are switched on there may be an uneven load on the 3 phases;
this uneven load may cause older residual current circuit breakers to
trip.
Here a modern make of residual current circuit breaker is to be used
that will tolerate such asymmetries during the switch-on process.
1.1.5.
Surrounding area
TopCon power supplies are generally forced-air cooled. Despite the
very high efficiency, a power loss occurs in the components that must
be dissipated in the form of heat to the surroundings. The energy is dis-
sipated with the aid of forced ventilation to the rear of the TopCon pow-
er supply.
It is to be ensured that the rooms in which TopCon power supplies op-
erate are cool and therefore the heat produced can actually be re-
moved.
Active cooling is, however, generally unnecessary.
The forced ventilation discharges air from the rear side of the
TopCon power supply.
It is to be ensured that there are no undesirable effects (e.g. stirring up
of dust or sand, deformation due to the action of heat etc.) due to the
flow of air and the heat, which at high load may be powerful.
On TopCon models with the water cooling option, a large portion of the
power loss produced is dissipated via the cooling circuit.
Here it is to be ensured the cooling liquid feed is not too warm. Further
requirements on the cooling liquid are given in the option description
from p. 91.
