7. Service and Replacement
PV Powered provides service guidelines for disconnecting and replacing
an inverter.
Always request and receive a replacement prior to
separating the inverter from the Integrated AC/DC Disconnect
assembly.
PV Powered maintains an advanced replacement policy
which provides qualified personnel with a similar inverter for immediate
replacement of the unit being removed.
In the unlikely event the inverter requires replacement, the disconnect
remains in place. Only the inverter is removed and immediately replaced.
Note:
If the inverter cannot be replaced immediately, it is the
qualified service personnel’s responsibility to provide ¾”
(1.9 cm) water-tight plugs as specified by UL 514B. These
plugs need to be installed in the disconnect’s knockouts to
protect the inside of the disconnect unit from exposure to the
elements.
7.1 Accessing the Wiring Terminals
1. On the disconnect, move the AC/DC handle to the OFF position.
Note:
The AC/DC disconnect switch must be in the off position
before the lid can be removed.
Note:
The load side terminals of the AC and DC source circuits
may still be energized.
!
DANGER
Risk of Electrical Shock. Allow five (5) minutes for internal
power to dissipate prior to entering the enclosure cabinet. Ensure
all terminals are voltage free with the use of a multimeter.
!
DANGER
Risque de choc électrique. Laisser cinq (5) minutes à la tension
interne pour se dissiper avant d’entrer dans la chambre du
boîtier. S’assurer que toutes les bornes ne sont pas sous tension à
l’aide d’un multimètre.
2. Remove the screws located around the front perimeter of the inverter
and remove the lid.
3. Remove the screws around the front edge of the disconnect and remove
the lid.
Now the wiring terminals in the inverter/disconnect unit are accessible.
The terminal connections are located inside the inverter on the Power
Distribution Board board at the bottom of the cabinet.
