Figure 3b - Front View with GMT Fuses (configuration B)
Figures 3a and 3b show the two system configurations as viewed from the front with breakers 
and fuses respectively.  Following is a description of each section.
8.1 
From left to right there are 3 rectifier slots.  Each slot can accept one rectifier from 
the Sigma Series rated up to 650W output power.  Only identical model rectifiers of 
appropriate output voltage may be installed at the same time.  For example, a nominal 
-48V system may contain between 1 and 3 model RSG48/10-Z OR between 1 and 
3 model RSG48/12-Z but not a mixture of the two types.
8.2 
To the right of the rectifiers are 7 LED indicators which display various status and 
alarm conditions.  These are described in more detail in section 10.
8.3 
On the right hand side of the unit is the DC distribution section which may contain 
between 1 and 5 circuit breakers (configuration A) or a 10-way GMT fuse block 
(configuration B).
