Manual EM-box 3
Hardware 3.1 - REV 3B - JAN 20
Page 6
From the EM-box the charging cable to the bow battery is connected to connector (8). If the state of charge of the bow
battery is to be recorded, a shunt SHC 612 is required in the negative line directly at the bow battery.
The charging line from the EM-box to the bow battery must be protected with an additional high-current fuse on the
bow battery, as well as the bow thruster and/or the anchor winch.
The battery disconnector consists of
a manual main switch (e.g. BH 400, BH 500) or
for load currents up to 260A use a main switch FBC 265 remotely controllable via the system monitor PSM2
or
for load currents above 260 A (e.g. for bow thrusters) from a remotely controllable main switch FBR 500 and a
control interface TSC, which is controlled via the system monitor PSM2.
2.3 Connection of two alternators
Figure 2.3: connection of two alternators
a) If the total current of the two alternators is less than 250 A, the two alternators can be connected to terminals
(-1/+1) and (-2/+2) (left figure).
b)
If the charging current of one alternator is greater than 150 A, the two alternator inputs (-1/+1) and (-2/+2) can
be connected in parallel (right figure).
