Figure A5-1, Attaching Knockout Plate
A5 Knockout Plate
A Knockout Plate is provided to run conduit from the top of the MP enclosure, or for use as a
safety plate.
If you are not installing a Magnum inverter into the top of the MP enclosure, then the
knockout plate can be used to run conduit from the MP enclosure to another inverter/device. If the
Magnum inverter is ever removed for service and the AC bypass breaker is used to continue to
power the inverter loads, then the knockout plate can be attached and used as a safety plate to
prevent accidental access to live electrical circuits inside the MP enclosure.
WARNING: If the knockout plate is used as a safety plate, the battery cables from the
top of the DC disconnect must be prevented from touching the metal knockout plate
or a short circuit to the battery bank may occur – causing very lethal currents. Either
remove these cables or isolate them (i.e., using electrical tape/rubber caps), do not
rely ONLY on turning the DC disconnect switch OFF.
Info: Eight #10-32 x 3/8” Pan head, T25 Torx drive, thread cutting screws; and eight #10
lock washers are used to secure the knockout plate to the enclosure.
Info: Before removing the appropriate knockouts, think about whether you are going
to use cable clamps, or conduit and all the different wiring required.
