Installation manual
Installing leakage protection at the output of each power block in master-slave units is not allowed.
5.4. Electrical connection
Once the unit has been mounted in its final position and has been solidly secured, make the electrical connections
to it.
Care must be taken to ensure the equipment is not live when accessing its interior.
All the doors on the cabinet are arranged so that they can only be opened when the AC thermomag-
netic circuit breaker, the DC circuit breaker and any auxiliary external supplies are disabled.
Since NAC models do not include an automatic AC circuit breaker, the system's AC breaker must be
operated under load conditions.
When checking that there is no voltage, wearing dielectric gloves and safety goggles approved for electrical hazards
is required.
While the door is open, do not alter the position of the thermomagnetic or CD circuit breaker, do not
operate the controls on the door nor apply force to the internal electrical devices which they control.
They must also be in the OFF position for the door to be able to be closed.
After setting the AC thermomagnetic circuit breaker, the DC circuit breaker and any auxiliary exter-
nal supplies to OFF, wait at least 10 minutes before opening the door. Internal capacitances may
still hold hazardous voltages.
During inspection and handling work:
Take care, since even with the AC thermomagnetic and the DC circuit breaker on OFF, cables directly
connected to the grid or panels may still hold hazardous voltages. This includes feed plates and
wires between switches/breakers.
As long as the panels are exposed to the light, the DC cables will carry potentially dangerous voltage
levels.
During handling work:
Remove all sources of voltage to the equipment: the grid, the PV array and any auxiliary power
supply.
After setting the AC thermomagnetic and DC circuit breaker to OFF, wait at least 10 minutes before
opening the door. Internal capacitances may still hold hazardous voltages.
