Relay Outputs
The 8720MC Drive has four discrete outputs in the form of normally
open dry relay contacts. The fault outputs from the 8720MC Drive are
supplied at terminal blocks. Fault outputs provide warning or fault
signals based on drive programming. The following values are the
contact ratings for the programmable relays:
Figure 2.15 shows a typical isolated relay output circuit. Use #16 to
#18 hook-up wire, Alpha 3075 or 3077 or equal.
