Auxiliary contacts

Auxiliary contacts will be shipped loose. Use Table 1 and Figure 3 to apply A (NO) and B (NC) contacts
for correct operation. Each source has two separate mounting points capable of holding up to two aux
contacts each for position indication, for a total of four per source. There is no restriction on using
NO, NC, or both in any location.
Note: Auxiliary contacts are very difficult to remove once applied!
