Wiring ProCharger™ CR cable junction box
Waterproof 1⁄2” cable fitting or conduit fitting
Cover the module with an opaque
material during installation
Installing a ProCharger™ CR
junction box
Match the polarities of the
cables and terminals when
making the connections.
Opening the junction box
}
The ProCharger™ - CR junction box has
four captive screws that secure the lid to
the base. To remove the lid, loosen the
screws with a small flat or Phillips screw-
driver.
}
Once wiring is complete, install the
junction box lid and tighten screws to
0.5 - 0.7 Nm (4 - 6 in-lb.).
Caution, DO NOT OVERTIGHTEN
the lid screws.
}
Do not use sealant to bond lid to its base.
Wiring
}
Remove the knockout plug from the entry
by carefully punching it out with a screw-
driver.
}
Slide the foam seal into the cavity behind
the cable entry and press it down using a
screwdriver.
}
Strip 16 mm of insulation from the end
of the wire. Wire size must range from 8
AWG - 14 AWG (1.5-10 mm²)
}
Pass
only one
wire through the wire entry
by pressing it through the foam seal.
}
Route the wire around the strain relief,
and then pass the bare end between the
clamping plate and the washer of the
screw. Tighten the screw to a maximum
torque of 2.3 Nm.
Waterproof 1⁄2” cable fitting or
conduit fitting
You will need a UL-approved 1⁄2” cable fit-
ting. Refer to the manufacturer’s instructions.
}
Remove the knockout plug by placing the
tip of a screwdriver at the edge of the
plug and striking the screwdriver with a
hammer.
}
Attach the fitting to the junction box and
leave it loose.
}
Pass the wire through the fitting and route
it to a terminal. Be careful to select the
proper polarity.
}
Insert the wires between the clamp-
ing plates and the washer of the screw.
Tighten the screw to a maximum torque of
2.3 Nm.
}
Tighten the fitting.
The same procedure should be used
for a conduit fitting.
Interconnecting several modules with
ProCharger™ cable junction boxes
Use conduit fittings in all places
where the wiring is accessible to
children or small animals.
Series circuit:
}
Connect the negative terminal of each
module to the positive terminal of its adja-
cent module.
}
Fasten loose lengths of wiring using UV-
and weather-resistant cable clamps.
}
At the first and last modules in the series,
replace the regular cable fitting for the
wire leading away from the module with
a conduit fitting. To remove the fitting,
loosen its lock nut.
}
If a regular cable fitting is present at the
first and last modules of the series, replace
it with a conduit fitting.
Parallel circuit see “Comparison of series and
parallel wiring“, page 8.
Use a conduit fitting that can be used to route
the cable leading from each module group
connected in parallel.
After making the electrical
connections …
}
Replace the covers on the
junction boxes and carefully
tighten the four retaining screws
(0.5-0.7 Nm). Do not apply any
supplementary sealant to the
junction boxes.
