Installation manual
6. Commissioning
6.1. Equipment inspection
This section contains the instructions for operating the equipment once it is correctly wired and sealed.
When an Ingecon
Sun Lite U unit is to manage all or part of a generating plant, a check should be made to ensure
®
that the plant status is correct before starting up the unit.
Each plant has its own particular characteristics, depending on the country of location and other specific conditions.
In any event, before start-up, it should be ensured that the installation is compliant with all applicable legislation and
regulations and that at least the part which is to be powered up, has been completed.
6.1.1. Inspection
Prior to the inverter power-up, a general inspection of the equipment should be made, primarily consisting in:
Cabling inspection:
•
Check that the cables are firmly connected to their connectors.
•
Check that the cables are in good condition and that there are no nearby hazards which could lead to the
deterioration of the cables, such as intense heat sources, sharp objects or devices which could impact against or
pull on the cables.
Check that the equipment is firmly secured
•
Check that the unit is firmly anchored and runs no risk of falling.
DC Circuit breaker
•
Check that the circuit breaker is in the ON position.
6.1.2. Hermetic seal
During installation, a check should be made to ensure that the equipment connection operations have not altered the
unit's NEMA rating.
Ensure that the connectors are correctly tightened and that the enclosure, and any cable glands, are correctly sealed.
Cover
If the front cover has been opened at any time, anchor it to the unit with its four Allen screws, following the guidelines
indicated below:
•
Lubricate the screws.
•
Manually insert the four screws into their threaded holes.
•
Screw down the screws to a maximum torque per screw of 5 Nm (Newton meter) using a calibrated tool.
•
Check for airtightness.
CAUTION
The guarantee does not cover damage caused by the inadequate sealing of the equipment.
Whenever the equipment is opened, it is mandatory to lubricate the screws before re-closing in order to prevent the
screws from jamming or seizing.
Use the keypad and flat screen to check that the variables monitored have coherent values. It is necessary to adjust
the date, time, grid configuration and the grounding type of the equipment.
6.2. Power-up
Once you have made a general visual inspection, checked the cabling and ensured that the unit is sealed correctly,
you can then proceed to power up the equipment, whilst maintaining it in the stop position. Follow the guidelines set
out in the equipment-specific instruction manual.
