Overcurrent
protection
Terminal covers Color-coded snap-on DC terminal covers are included to avoid accidental
contact with the terminals. Terminal covers are required for all installations, even
if a Conext XW+ Conduit Box is used. It is also recommended that the shank of
the ring terminals (cable lugs) be covered with heat shrink or some other form of
insulation.
WARNING
FIRE HAZARD FROM DC OVER CURRENT
Your local electrical code may require both DC over current protection and a
DC disconnect switch for residential and commercial electrical systems. Fuses
and disconnects must be sized to protect the wiring in the system and are
required to open before the wire reaches its maximum current carrying
capability.
Failure to follow these instructions can result in death or serious injury.
Note: Your local electrical code may require both overcurrent protection and a
disconnect switch for residential and commercial electrical systems. These items
are not supplied as part of the inverter, but are included with the Conext XW+
Power Distribution Panel.
