Lynx Shunt VE.Can

6. Installation

In this section:

6.1. Mechanical connections

6.1.1. 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 the negative busbar.

6.1.2. 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 appendix 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 M8 holes and bolts on the left and right. Take care that the modules correctly slot into the rubber joiner recesses.

  • Place the washer, spring washer and nut on the bolts and tighten the bolts using a torque of 14Nm.

  • Mount the Lynx assembly in its final location using the 5mm mounting holes.

6.2. Electrical connections

6.2.1. 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 module need to have been fitted with M8 cable lugs.

  • 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 with a torque moment of 14Nm.

6.2.2. Connect RJ10 cable(s)

These instructions only apply if the system contains Lynx distributor(s) together with a Lynx Smart BMS or a Lynx Shunt VE.Can.

There are two RJ10 connectors in each Lynx Distributor, one on the left and one on the right. See below drawing.


Locations of the RJ10 connectors and RJ10 cable recesses on the Lynx Distributor and the Lynx Shunt VE.Can

To connect the RJ10 cables between the various Lynx modules do the following:

  • Plug one side of the RJ10 cable in the RJ10 connector of the Lynx Distributor with the retainer clip of the RJ10 connector facing away from you.

  • Feed the RJ10 cable through the recess at the bottom of the Lynx Distributor, see above picture.

  • To connect to a Lynx Shunt VE.Can, feed the cable through its bottom recess and plug the RJ10 cable into the RJ10 connector.

6.2.3. Connect the temperature sensor

An optional battery temperature sensor can be connected to the green terminal with the + and - symbol.

The connector can be removed from the terminal, for easy connection.

The temperature sensor is polarity sensitive. Connect the black wire to the - terminal and the red wire to the + terminal.

6.2.4. Connect the alarm relay

The alarm relay connector is the black 2-way connector. See below image for its location.

6.2.5. Place main fuse

Place the main fuse in the Lynx Shunt VE.can.

Be aware that if the positive bus is already powered, the moment the fuse is placed the system will become live.

6.2.6. Connect the GX device

Connect the Lynx Shunt VE.Can VE.Can port to the GX device VE.Can port using a RJ45 cable.

Multiple VE.Can devices can be interconnected, but make sure that the first and the last VE.Can device both have a VE.Can RJ45 terminator installed.

Power the GX device from the output of the Lynx Shunt VE.Can or a Lynx distributor connected to the output of the Lynx Shunt VE.Can.

6.3. Configuration and settings

6.3.1. Settings Lynx Shunt VE.Can

Once powered up and connected to a GX device, navigate to the Lynx Shunt VE.Can settings menu on the GX device to make and change settings.

Most settings can be left to their default values, but there are a few essential settings to make by your own :

  • Set the battery capacity.

  • If lithium batteries are used, specific battery monitor settings are needed. Refer to the battery monitor settings chapter.

  • If the alarm relay is used, set the alarm relay parameters.

For a full overview and an explanation of all battery monitor settings, refer to the battery monitor setting chapter
