3.1 Opening the equipment and access
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
10 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.
Inverter access
All the cables access the unit through the PG cable glands located in the cabinet base
as indicated in the following drawings. If quick connectors option is chosen, they are
located on the base too.
