Figure 4.9 – Voltage Sensing Board Dimension Diagram
The voltage sensing board (VSB) should be mounted adjacent to the
power stacks (refer to Figure 4.9 for dimensions). All connection
points are to be made accessible. The same VSB is used regardless of
the system voltage.
Connect the voltage sensing board to the L1 to L3 and T1 to T3
terminals of the power stack (refer to Chapter 7). Observe the
connection points at the voltage sensing board per Table 4.E and
Figure 4.10.
Specifications for wire used on medium voltage connections:
UL style 3239, #18AWG, 40 KVDC silicone rubber insulated wire.
