3. Optional Accessory: Anderson Solar Cable (sold separatley) suitable for BCDC Dual Input Chargers
   (BCDC1225D, BCDC1240D and BCDC1250D).

INSTALLATION

Securing the Terminal Block
Find a secure location for the Terminal Block between the auxiliary battery and BCDC. Ensure that the BCDC wiring lengths reach location before fitting the Terminal Block.
Secure the Terminal Block to a fixed structure using the four M5 Screws, M5 Flat Washers and Nylon Nuts supplied. Alternative fasteners may be required depending on the installation.

Precautions Before Connecting Cables

CAUTION
Ensure all cables are clear from any moving parts or sharp edges and are not exposed to excessive heat.
IMPORTANT: Each terminal slot must have the same coloured cable, do not mix or crossover the coloured wires.
Protective conduit can be used in areas where a cable may have exposure to abrasion or heat.

Connecting BCDC Wires into the Terminal Block
Ensure the main power cables from the BCDC, Brown, Black, Yellow, and Red are stripped back to 14 mm (0.55″) before routing to the Terminal Block.
Unscrew the grub screws in the Terminal Block using a 4 mm (5/32″) hex-head tool to allow each wire to be fitted. Insert the stripped end of the cable into the Terminal Block and tighten the grub screw. Torque to 6.8 – 7 Nm (60 – 62 lb-in) to clamp the wire securely. Repeat on the Brown, Black, Yellow and Red wires from the BCDC.
*NOTE: For an Auxiliary Battery requiring a higher voltage charging profile, combine the Orange wire to the Black or Red cable — see ‘Profile Select’ in your BCDC Instruction Manual.
NOTE:** Only REDARC’s BCDC1225D, BCDC1240D and BCDC1250D Dual Input Battery Chargers will have the Yellow Cable for solar connection.

WIRING CONNECTIONS

Connecting the Brown Cable
Before making any connections, layout and run the Brown Cable, MIDI fuse and the short Red Cable from the auxiliary battery to the Terminal Block. Trim any excess of the Brown Cable to suit your setup and strip back to 14 mm (0.55″).

Secure the Brown Cable to the Terminal Block using a 4 mm (5/32″) hex-head tool ensuring that the cable is installed in the same terminal slot as the Brown Cable from the BCDC.
Using supplied cable ties, secure the cable to existing vehicle wiring where possible every 200 mm (8″).
Connect the Brown Cable to the auxiliary battery using the MIDI fuse and the short Red Cable.

Securing Brown Cable to Terminal Block

Assemble one MIDI fuse into the supplied holder, see Figure 4.1.2. On one side of the MIDI fuse, fit the short Red Cable (smaller lug end).
Next, fit the lug end of the Brown Cable to the other side. Secure both lugs with the supplied nuts, torque to 2 Nm (17.7 lb-in) and close the cover. Connect the other end of the short red wire to the auxiliary battery positive post.

Securing Brown and Red Cable MIDI Fuse

Connecting the Black Cable

• Connect the Black Cable Lug to the negative input of the auxiliary battery (or chassis connection point) and run the black cable to the terminal block.
• Trim any excess cable and strip back to 14 mm (0.55″) before routing the cable to the terminal block.
• Secure the Black Cable using a 4 mm (5/32″) hex-head tool, ensuring that the cable is installed in the same terminal slot as the Black Cable from the BCDC.

Black Cable to Terminal Block

AUXILIARY BATTERY CHASSIS CONNECTION
The auxiliary battery negative must be connected to the same potential as the vehicle electrical system chassis. An appropriate cable gauge capable of carrying the sum of all the connected auxiliary loads, and the auxiliary battery charge current should be chosen.
The Chassis Ground cable is not supplied with the BCDC Wiring Kit as it is expected that this would form part of the auxiliary battery installation.

Black Cable and Chassis Ground connection

Connecting the Long Red Cable
Before making any connections, layout and run the long Red Cable, MIDI fuse and the short Red Cable from the start battery to the Terminal Block. Trim any excess of the long Red Cable to suit your setup and strip back to 14 mm (0.55″).

Secure the long Red Cable to the Terminal Block using a 4 mm (5/32″) hex-head tool, ensuring that the cable is installed in the same terminal slot as the red cable from the BCDC.
Using supplied cable ties, secure the cable to existing vehicle wiring where possible every 200 mm (8″).
Once all connections to the Terminal Block have been made, place the plastic cover on top and secure with a cable tie.

Red Cable to Terminal Block

Connect the long Red Cable to the start battery using the MIDI fuse and the short Red Cable.
On one side of the MIDI Fuse, fit the short Red Cable (smaller lug end) and the lug end of the long Red Cable to the other side (see Figure 4.3.2). Secure both lugs with the supplied nuts, torque 2 Nm (17.7 lb-in) and close the cover. Connect the other end of the short Red Cable to the start battery positive terminal (see Figure 4.3.2).
Check the operation of the system.

Red Cable Connected to Start Battery

BLUE WIRE CONNECTION

The Wago® Connector and Boot is used to connect the blue wire from the BCDC to the supplied Blue Wire with attached Mini Blade Fuse with cover and connected Red/Blue Wire.
The Blue Wire allows your battery charger to know if the vehicle’s ignition is switched on, indicating when the vehicle is in use rather than sitting idle with the ignition and engine switched off.
Vehicles with a variable voltage alternator or with an Idle-stop alternator are required to connect the blue wire to a suitable ignition point as directed in your battery charger’s instruction manual.
If your vehicle is equipped with a ‘Stop-Start’ system, where the engine may turn off automatically when you slow down to a stop, the blue wire must be connected to an ‘Engine On / Engine Running’ signal. This is intended to maintain charging whilst the engine is running, and quickly reduce charging when the engine stops.
NOTE: For standard alternator vehicles the blue wire is not required.

BLUE WIRE INSTALLATION
Connect Red Wire with Blue stripes to ignition point or engine on / off signal for stop start vehicles and strip back any excess Blue wire before inserting into the Wago® Connector.
Using the Wago® Connector and Boot, feed the blue wire from the BCDC into one of the legs of the Boot and the supplied Blue Wire into the other leg. The legs of the Boot can be trimmed to permit different gauges of wires. Trim the blue wires to remove any excess if necessary to suit your setup, ensuring that the wire is stripped back 12 mm (0.5″).
With the levers of the Wago® Connector lifted to the ‘open’ position, fit one wire into each slot and close the levers to clamp the blue wires. After both wires are secured in the Wago® Connector, push the assembly into the Boot and close the lid.
Add electrical tape around the wire entry in the legs for additional protection against water ingress, and around the main body to secure the lid.

LITHIUM PROFILE CONNECTIONS

For Auxiliary Batteries requiring Lithium Profile use the second supplied Wago® Connector and Boot to secure the green and orange wire from the BCDC.
Feed the green and orange wire from the BCDC through the legs of the Boot, see Figure 6.1. The legs of the Boot can be trimmed to permit different gauges of wires. Trim the orange and green wires to remove any excess if necessary to suit your setup, ensuring that the wire is stripped back 12 mm (0.5″).
With the levers of the Wago® Connector lifted to the ‘open’ position, fit one wire into each slot and close the levers to clamp the green and orange wires. After both wires are secured in the Wago® Connector, push the assembly into the Boot and close the lid.
Add electrical tape around the wire entry in the legs for additional protection against water ingress, and around the main body to secure the lid.
