Parallel use (MasterBus only)

For load currents which exceed 300A continuous current, more than one MasterShunt 500 can be installed to monitor the
same battery (bank). The MasterShunt 500s are then configured in parallel to the battery. The following figure shows the
parallel configuration of two MasterShunt 500s (3) and (4) and other products.

2. Bow thruster

Figure 3 : Parallel system example
Note: When also using older versions of the MasterShunt 500 in parallel setup, make sure to select the new version
(7702011x) as master and the older version as slave.
For parallel setup of two MasterShunt 500s, execute the following steps:
1. First reset any pre-used MasterShunt 500s to factory settings.
2. During First start up select Advanced mode/ Parallel mode on one of the MasterShunt 500s, this will become the Master.
3. Select the serial number(s) of the other MasterShunt 500(s), Refer to Figure 1. These MasterShunt 500(s) will be the
slave(s).
After pressing the "Complete" button, the measurements of all paralleled MasterShunt 500s are combined and shown as one
MasterShunt 500. The currents however are shown separately! This means, renaming the MasterShunt 500s can be
convenient.
