Installation Step-By-Step - Mastervolt MasterShunt 500 User And Installation Manual

Points to consider:
˗
Up to 40 devices can be connected together on a single backbone.
˗
Make sure the CZone network has two terminating resistors, one at each open end of the backbone.
˗
The electric power for the network comes from a battery or power supply. Make sure that it delivers enough power and
is positioned as close to the middle of the backbone as possible to reduce voltage drop.
˗
The CZone/MB drop cable includes a diode to prevent power from the MasterShunt 500 getting on the CZone
backbone.

in a MasterBus network
Use an RJ45 MasterBus cable (not included) and daisy chain the MasterShunt 500 to the other MasterBus devices,
forming a local data network.
Points to consider:
˗
Connections between the devices are made by standard straight MasterBus cables. Mastervolt can supply these
cables.
˗
Up to 63 MasterBus devices can be connected together.
˗
MasterBus needs a terminating device on both ends of the network.
˗
The electric power for the network comes from the connected devices according to the rule: 1 powering / 3 non-
powering. Spread the powering devices over the network
˗
Do not make ring networks.
˗
Do not make T-connections in the network.
CAUTION!
Never connect a non-MasterBus device to the MasterBus network directly! This will void warranty of all
MasterBus devices connected.
For more details on networks, please contact your Mastervolt supplier.

Installation step-by-step

Step 1. Disconnect the electrical power.

Switch off all consumers;

Switch off all charging systems;

Disconnect the positive battery poles;

Check with a suitable voltmeter whether the entire DC installation is voltage free.
Step 2. Position the MasterShunt 500 close to the battery, between the battery and the load/charger.
Note: Remember to put the cones around the cables before connecting!
Step 3. Connect the loose positive battery cable to the upper left connection (A) and the positive load cable to the upper right
connection (B).
Step 4. Connect the negative battery cable to (D) and the negative load cable to (C).

Use cable lugs to accomplish sufficient electrical contact between the wiring and the MasterShunt 500.

The recommended tightening torque is 15-20 Nm.
Note: The charger must be connected at the load side of the MasterShunt 500!
CAUTION!
Leave the positive battery cable disconnected from the battery.
Step 5. Option: place a fuse. See section 4.4.
Step 6. Option: connect the MasterShunt 500 to the CZone or MasterBus network.
