Introduction

The Lynx Power In

The Lynx Power In contains a positive and negative busbar with 4 connections for batteries, loads or chargers and a ground connection. It is part of the Lynx Distribution system and is available in two versions, with M8 or M10 busbar. Note that M10 refers to the busbar connection joints where the modules are connected to each other. The fuse and cable connections are always M8.

The Lynx Distribution System

The Lynx Distribution System is a modular busbar system that incorporates DC connections, distribution, fusing, battery monitoring and/or Lithium battery management. For more information, see the DC Distribution Systems product page.
The Lynx Distribution System consist of the following parts:

Lynx Power In – A positive and negative busbar with four batteries or DC equipment connections, available in two versions, with M8 or M10 busbar.
Lynx Distributor – A positive and negative busbar with four fused connections for batteries or DC equipment and fuse monitoring, available in two versions, with M8 or M10 busbar.

System Design

. Lynx distribution system parts

A Lynx distribution system usually consists of a single Lynx Shunt VE.Can module or a single Lynx Smart BMS module.
The choice between a Lynx Shunt VE.Can or a Lynx Smart BMS depends on what type of batteries are used in the system. The
Lynx Smart BMS can only be used with the Victron Energy Lithium Smart Batteries, while the Lynx Shunt VE.Can is suitable for all other batteries.
Then, single, multiple or a combination of Lynx Distributor modules and/or Lynx Power In modules are added.
Together they form a continuous negative and positive busbar with DC connections and, depending on the configuration,
integrated fuses, a battery monitor and/or lithium battery management.
It is also possible to just use Lynx Power In modules and/or Lynx Distributor modules without a Lynx Smart BMS module or a Lynx
Shunt VE.Can modules. This for situations where battery monitoring or battery management is not needed.

Interconnecting Lynx modules

Each Lynx module can connect to other Lynx modules on the left side and on the right side.
If the Lynx module is the first in line, the last in line or is used by itself, it is possible to connect batteries, loads or chargers directlyto these connections. However, we do not generally recommend this because additional insulation and fusing are needed.

The example below shows a Lynx system consisting of a Lynx Power In, Lynx Shunt VE.Can and Lynx Distributor. Together, they
form a continuous busbar with unfused battery connections, battery monitor, main system fuse and fused load connections.

Figure 1. Example of Interconnected Lynx modules without their covers

(Lynx Shunt VE.Can)

The example below shows a Lynx system consisting of a Lynx distributor, Lynx Smart BMS and another Lynx Distributor. Together, they form a continuous busbar with fused battery and load connections, battery monitor, BMS system and contactor

Orientation of Lynx modules

If the Lynx System contains a Lynx Shunt VE.Can or Lynx Smart BMS, the batteries always have to be connected to the left side of the Lynx System and the rest of the DC system (loads and chargers) connect to the right side. This so the battery state of charge can be correctly calculated.
The Lynx modules can be mounted in any orientation. Should they be mounted upside down so that the text on the front of the units is upside down as well, use the special stickers included with each Lynx module so that the text is orientated the correct way.

System Example – Lynx Power In only

In this system a Lynx Power In is used by itself. Multiple Lynx Power In modules can be connected to each other thus creating a longer busbar with more connections for batteries and/or loads.
The Lynx Power In does not contain fuses. All connected loads, chargers or batteries need to be fused externally.

System example – Lynx Shunt VE.Can, Lynx Power In, Lynx Distributor and

lead acid batteries

This system contains the following components:

Lynx Power In with 4 paralleled 12V lead acid
Identical cable lengths for each
Lynx Shunt Can with main system fuse and battery monitor.
Lynx Distributor with fused connections for inverter/charger(s), loads and Note that additional modules can be added if more connections are needed.

System sizing

Current rating Lynx modules

The Lynx Distributor, Lynx Shunt VE.Can and the Lynx Power In are rated for a nominal current of 1000A for 12, 24 or 48 System voltages.

See the table below for an idea of how much power the Lynx modules are rated at different voltages. The power rating will indicate how big the connected inverter/charger system can be. Remember that if inverters or inverter/chargers are used, the batteries will power both the AC and DC systems. Also, be aware that a Lynx Smart BMS or a Lynx Ion (now discontinued) can have a lower current rating.

| 12V| 24V| 48V
---|---|---|---
1000A| 12kW| 24kW| 48kW

Fusing

The Lynx Power In does not have spaces for fuses, fusing needs to be done externally. For more information on fuses and fuse holders, see the Fuses & Fuse holders product page.
Always use fuses with the correct voltage and current rating. Match the fuse rating to the maximum voltages and currents that potentially can occur in the fused circuit. For more information on fuse ratings and fuse current calculations see the Wiring Unlimited book

Cabling

The current rating of the wires or cables used to connect the Lynx Power In to batteries and/or the DC loads, has to be rated for the maximum currents that can occur in the connected circuits. Use cabling with a sufficient core surface area to match the maximum current rating of the circuit.
For more information on cabling and cable thickness calculations, see our book, Wiring Unlimited.

Mechanical connections

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

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 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 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 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 (M10) holes and bolts on the left and 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 (17Nm for the M10 model).
Mount the Lynx assembly in its final location using the 5mm mounting

Electrical connections

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
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 (17Nm for the M10 model).

Figure 3. Correct mounting sequence DC wires

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.

Connect the negative wires

Remove the cable separator post if the wire diameter exceeds 10mm

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 Power In at a slight sideways angle in case better access is needed.

Flip up the cable separator to reach the negative connections

Positive connections

Connect all positive wires.
Power the Lynx system by connecting the positive battery pole(s).

Commissioning the Lynx Power In

Commissioning sequence:
Check polarity of all DC cables
Check cross sectional area of all DC cables.
Check if all cable lugs have been crimped correctly.
Check if all cable connections are tight (don’t exceed maximum torque).
Tug slightly on each battery cable to check if the connections are tight and if the cable lugs have been crimped correctly.

Troubleshooting and Suppor
