2. System DC Cables Connections
As illustrated in Fig. 2-2, the terminals for DC cable of the power system are on the
right side of the system, symbols are “BATT.(-)”, “LOAD(-)”, “BATT(+)”, and
“LOAD(+)”.
Before connection, remove the transparent cover on the power distribution panel,
and take out the small baffle on top of the terminals corresponding to the DC
connections mark along the arrowhead direction.
“BATT.(-)” represents connection position of battery voltage negative, its
corresponding connection terminal symbol is “B1B2”, which represents connection
positions of voltage negative of battery group 1 and battery group 2 separately. The
corresponding control circuit breaker is shown as 2 in Figure 2-2, marked as “BATT
63A”.
“BATT.(+)” represents connection position of battery voltage positive, its
corresponding connection terminal symbol is “++”, which represents connection
positions of voltage positive of battery group 1 and battery group 2 separately.
“LOAD.(-)” represents connection position of load voltage negative, its
corresponding connection terminal symbols are “1-2-3-”, “B2-3-”, and “4-4-”, which
represent connection positions of voltage negative of load 1, 2, 3, 4 and emergency
lighting equipment (B) separately. The electric performances of the connection
terminals with the same symbol are parallel relations, and user can use selectively.
The corresponding control circuit breakers are shown as 3, 4, 5, and 6 in Figure 2-2,
marked as “LOAD1 10A”, “LOAD2 20A”, “LOAD3 20A”, and “LOAD4 50A”. The
connection terminal with symbol “B” can be used as the connection terminal for
emergency lighting equipment, and it has the parallel relationship with the
connection terminal “B1B2” of battery voltage negative, and is not controlled by the
load circuit breaker.
“LOAD.(+)” represents connection position of load voltage positive, its
corresponding connection terminal symbols are all “+”, and used with the
connection terminals of load voltage negative together. The specifications for each
connection terminals are shown in Table 2-3.
