Fuses Replacement; Maintenance - NDS Smart-in SM Series User Manual

11. FUSES REPLACEMENT:

The inverters are protected by our integral electronic circuit and will automatically
reset.
The inverters are fitted with internal fuse protections. If the battery is connected with
reverse polarity, the fuses burn protecting the system, so it is necessary to open the
device to replace them with the reserve ones of the same type. Normally after you
replace the new fuse, the inverter restart automatically. Sometimes it is possible that
there are additional faults for which it is necessary to contact the service of NDS.
OPTIONALS:
– The inverters are all predisposed to connect to an external remote controller.
– For the low power models 400W and 600W, it is possible to have
connection cables with clamps.

12. MAINTENANCE:

Minimal maintenance is required to keep your inverter operating properly,
periodically you should:
• Clean the exterior of the unit with a damp cloth to prevent the accumulation of
dust and dirt and check that DC cables are secure and fasteners are tight.
• Make sure the ventilation openings on the DC panel and bottom of the inverter
are not clogged.
