Overcurrent protection
WARNING
DC OVER CURRENT
The NEC/CEC requires 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, serious injury, or equipment
damage.
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 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.
Note: The NEC/CEC requires 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 Power Distribution Panel (PDP).
