5 Maintenance and service

DANGER
The maintenance of this equipment can only be performed when there are
no live voltages present in this equipment and after it has cooled down for
at least 15 minutes. Failure to observe this requirement creates electrical
shock and burn hazards.
WARNING
The pollution degree of the conductor board is achieved by the use of
conformal coating that meets ANSI/UL 746E. Scratches or surface damage
can reduce the insulation protection of the device. So the board must be
handled with care.
This equipment needs very little maintenance if mounted in a proper PV combiner
box. These are the only maintenance tasks required every two years (please increase
the frequency of maintenance sessions if the device operates in very polluted/dusty
environment and/or is frequently subject to large temperature variations).
• Check the tightening torque of X1/X4, X2 and the hex screws of the negative copper
busbar with a torque wrench.
• Check the supply voltage with a multimeter
• Make sure the equipment remains well secured to the combiner box rail
• Visually inspect the RS–485 wiring
• Visually inspect the amount of dust/dirt on the equipment cover and on the PCB
surface. In case cleaning is needed, it shall be done with just a damp cloth.
No other solvent can be used to clean this equipment.
• Visually inspect the metal contacts of the terminal blocks. If there are signs of
corrosion the equipment may need to be serviced by Weidmüller.
