3.3.3.5. DC Connection for Standard Wiringbox
This section is intended for the Standard wirebox connections.
Refer to
Section 3.3.3.6
for connections to the H4 wirebox
connections.
1. Using the 1-1/2 inch openings
. Remove the factory
installed liquid-tight hole plugs from the DC knockout holes
in the wiring box and install 1-1/2 inch Trade Size conduit
and conduit fittings. If smaller conduit is needed use proper
weather-tight reducing bushings to ensure the wiring box
maintains it’s NEMA 4X rating. Confirm all fittings are
properly tightened, and route the DC source circuit
conductors through the conduit into the wiring box.
2. Using the removable gland plate.
Optionally, all DC input
cables from the PV source circuits may be routed through a
single larger knock-out hole inside the wiring box. The wiring
box includes removable gland plates that may be drilled or
punched for up to 2-1/2 inch Trade Size conduit.
a. Remove the
M6x18
screws
(4 pcs) securing the DC gland
plate to the wiring box. (see
Figure 3-23
) Removing the
gland plate before punching the hole is required to ensure
metal filings are not introduced into the wirebox.
b. Remove the DC gland plate and rubber gasket
c.
Use a punching tool to create desired hole size in the gland
plate.
d. Reattach the rubber gasket and DC gland plate to the wiring
box with the
M6x18
screws
(4 pcs).
e. Tool required: No. 3 Phillips head screwdriver, torque value
of 4Nm (35.4in-lbs)
