The system requires following next screwing prescriptions:
- Minimun distance between the center of thedrill on the concrete slab to
its borders of 3 in (76 mm).
- Diameter of the drill on the concrete slab to its borders of 0.31 in (8 mm).
- Minimun depth of thedrill on the concrete slab of 3 in (76 mm).
- Minimun thickness of the concrete slab of 4 in (102 mm).
- Torque of 14.75 lb-ft (20 Nm).
- Minimun depth of the screw of 2 in (51 mm).
5.3 Opening the equipment
Before opening the front door, make absolutely certain that there are no live
voltages inside the cabinet.
For this, the equipment needs to be disconnected from the PV array and
from the power grid.
LIkewise, it is essential to close the equipment before connecting it to the
PV array or power grid.
For Inspection, Operation or Manipulation tasks:
Make an electrical check to ensure that no part of the equipment is in
electrical contact with either the grid or any of the PV panels.
The use of safety gloves and glasses homologued for electrical risk
is compulsory to ensure lack of voltage.
After disconnecting the equipment from the PV array and power grid,
wait at least 5 minutes before opening the door. Due to its internal
capacitance, the inverter may maintain hazardous voltage levels.
Whilst the panels are receiving light, the DC cables may be under
hazardouse voltage levels.
