 The altitude compensation by DIP switch settings applies to Series E 400 amp vacuum contactors only. All 800 amp contactors are adapted
for altitude by altering the return springs. 800 amp contactors are to be set for 1 to 1000m (001 DIP setting).
 By-pass contactors in MV SMC applications must be set for 50 millisecond drop-out time.
Refer to Appendix A for typical drop-out time settings used when power fuses are provided by Rockwell Automation.
