Finish Conduit Attach: Hand tighten threaded
conduit cap to secure conduit nipple in place.
This will hold the QBox ashing in place when
securing it to the roof.
Secure to Roof: Screw the anchor bolts with
sealing washers through the mounting holes and
into the roof sheathing securing the QBox to the
roof. No pilot hole is required.
Close Lid: Close and thread the bolt into the nut
by hand. Then using a #3 Philips drive, turn bolt
until the top and bottom tabs securing the bolt
are ush.

To maintain the QBox Type 3R rating for wet locations,
all attached conduit hubs and cord grips must be
weathertight or suitable for wet locations and be listed
to the Standard for Conduit, Tubing and Cable Fittings,
UL 514B. The conduit hubs and cord grips can be
installed along any of the sidewalls of the QBox. The
drill starter along the outside of the QBox will ensure
that the connectors are centered vertically on the unit.
The QBox does not come with conduit hubs or cord
V. Wiring
WARNING
Before wiring of the QBox, ensure
all cables are de-energized. Do not
work with energized electrical cables.
Energized electrical cables are a shock
hazard.
WARNING
PV modules produce lethal levels of
electricity when exposed to light. PV
modules cannot be de-energized
unless all light sources are removed.
Disconnect all wires from the PV system
prior to installing or servicing the QBox.
Failure to do so could result in electric
shock leading to personal injury or
death.
CAUTION
In order to maintain warranty and Type
3R rainproof rating of the enclosure
the lid must close freely without
interference from the wires. Failure
to properly close the lid can lead to
excessive water ingress leading to an
electrical short and possibly a re.
grips due to site-specic needs. It is the responsibility of the installer
to specify the proper conduit or cord grip products for the installation.
Follow the installation instructions from the conduit hub and cord grip
manufacturer and follow all National Electrical Code, ASNI/NFPA 70
wiring methods and guidelines.
The QBox is nonconductive and therefore does not need to be grounded.
However, that also means the box cannot be used to maintain an
electrical bond between ttings. Ensure all proper jumpers or other
bonding mechanisms are in place per NEC.
The DC input and DC output circuits are isolated from the enclosure
and the system grounding, if required by section 250 of the National
Electrical Code, ANSI/NFPA 70, is the responsibility of the installer.
The Photovoltaic System Grounding shall be installed per the
requirements of Sections 690.41 through 690.47 of the National Electrical
Code, ANSI/NFPA 70 and is the responsibility of the installer.
The ground terminal for bonding is not provided. Grounding will need
to be provided as part of the nal installation and compliant with the
National Electric Code and local electrical codes. When installing a
conduit hub to the QBox that is intended for connection to a rigid conduit
system, install the hub to the conduit before the hub is connected to the
enclosure.
To maintain the QBox's 3R rating, the enclosure's top hinged cover
must be completely closed to the enclosure's base. In addition, all wires
should be pushed down and away from the cover so it closes freely
without resistance.
