JB4
Assembly Instructions
IP68 to a maximum depth of 1.3 metres.
Collingwood advise 0.75mm² round cable for this junction box. Minimum cable diameter is 6.5mm, maximum is 12mm.
Collingwood WC275 cable is ideal. For any positions with cable diameter 9.5mm or more, do not use the reducing adaptors.
Terminal block is 4 x 1.5mm².
Ideal wire stripping 1. Refer overleaf to wiring instructions, and wire the first JB4 connector block.
NOTE- ensure any link leads are sufficiently long before starting.

2. Break the four spacers
on the connectors.

A
A = 30-38mm
B = 6-12mm
C = 24-26mm
4. Insert reducing adaptors
into cable positions.
3. Determine which cable positions are to be used,
and on one part of the connector body, break the
pre-cracked membranes in those positions.
5. Fit the terminal block into
the connector body.
6. Determine which cable positions are to be used, and on the second part of the
connector body, break the pre-cracked membranes in those positions.
8. Close the box by pressing the
snap lock devices.
Repeat the above steps for each JB4.
The box can be reopened and resealed as necessary.

7. Insert reducing adapters into cable positions.
9. Fit and tighten the screws to lock
the box and secure the cables.

Above example for 6 LED units shows the last JB4 wired as per Diagram
2 (2 LED units).
For 7 LED units, the last JB4 is wired as per Diagram 3 (3 LED units).
In this way, any number of units can be wired in series, providing the LED
driver is not overloaded.
e.g. 9 units = 3 x 2 plus the last JB4 with 3 units.
NOTE- If desired, JB4s can be linked with only one LED unit on each JB4.
To do this, replace the LED connection with a loop wire.
For example, if LED unit 3 above is not required, connect a loop wire
across the two terminals instead of the LED unit.
