Power cables for Ingecon

via glands in the lower sides of the cabinet on both the left and right sides. The following drawings show these glands.
Power access
Grid Connection
Connection to PV panels
Access for communication cables or auxiliary inputs is located on the top of the left side of the DC cabinet. They are
shown in the above diagram.
The tapered grommets allow wire diameter of up to 40 mm.
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
thermomagnetic circuit breaker, the DC circuit breaker and any auxiliary external supplies are disabled.
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 external 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.
