5.1.1. Lynx module connection features
The Lynx module can be opened up by unscrewing the 2 cover screws.
The contacts on the left side are covered by a removable rubber sleeve.
Red is the positive and black is the negative busbar.

5.1.2. Mounting and interconnecting Lynx modules
This paragraph explains how to attach several Lynx modules to each other and how to mount the Lynx assembly into its final location.
For a mechanical drawing of the housing with dimensions and the location of the mounting holes, see the Enclosure Dimensions of this manual.
These are the points to take into consideration when interconnecting and mounting Lynx modules:
If Lynx modules are going to be connected to the right and if the Lynx module is fitted with a plastic barrier on the right side, remove the black plastic barrier. If the Lynx module is located as the most right module, leave the black plastic barrier in place.
If Lynx modules are going to be connected to the left, remove the red and black rubber sleeves. If the Lynx module is located as the most left module, leave the red and black rubber sleeves in place.
If the Lynx system contains a Lynx Smart BMS or Lynx Shunt VE.Can, the left side is the battery and the right side is the DC system side.
Connect all Lynx modules to each other using the M10 holes and bolts on the left and right. Take care that the modules are correctly slotted into the rubber joiner recesses.
Place the washer, spring washer and nut on the bolts and tighten the bolts using a torque of:
33Nm
Mount the Lynx assembly in its final location using the 5mm mounting holes.

5.2. Electrical connections
5.2.1. Connect DC wires
This chapter might not apply if the Lynx module is connected to other Lynx modules like this can be the case for the Lynx Smart BMS or the Lynx Shunt VE.Can.
For all DC connections, the following applies:
All cables and wires connected to the Lynx Class-T Power In need to have been fitted with M10 cable lugs. Cable lugs up to 120mm² or 3/8"-4/0 AWG can be used.
Pay attention to the correct placement of the cable lug, washer, spring washer and nut on each bolt when attaching the cable to the bolt.
Tighten the nuts using a torque of:
33Nm

5.2.2. Ground and Negative connections
Connect the ground wire
This only applies if the system requires a ground connection. There should only be one ground connection per system. The ground connection should be made after the Lynx Smart BMS, Lynx Shunt VE.Can or battery monitor shunt. For more information on system grounding, see the Wiring Unlimited book.
Ground connection Lynx Class-T Power In
Connect the negative wires
Remove the cable separator post if the wire diameter exceeds 10mm.
The cable separator posts are indicated in yellow
To reach the negative connections, swing the black cable separators upwards. The black cable separators can be temporarily removed by pulling them away from the Lynx Class-T Power In at a slight sideways angle in case better access is needed.
Flip up the cable separator to reach the negative connections
Negative connection Lynx Class-T Power In
5.2.3. Positive connections
Caution
Before making any positive connections, ensure the positive wires are not powered. Disconnect all positive cables from the battery before connecting them to the Lynx module. This to prevent accidental short circuits.
Connect all positive wires.
Power the Lynx system by connecting the positive battery pole(s).
