All wiring must conform to local and national electrical codes and ordinances.
The terminal markings are equivalent to most other manufacturers' types. Follow the original equipment manufac-
turers' recommendations for proper wiring.
Wiring
MAIN CONTACTS: These are the load contacts and are
identified by the terminals designated “M”. The M1-M2
contacts will always be the first set of contacts to close
and the last set to open. The M3-M4 contacts will always
be the second set of contacts to close and the second-to-
last set of contacts to open. The M5-M6 contacts will
always close last and open first.
AUXILIARY CONTACTS: These contacts are identified
by terminals designated “A”. During the ON cycle, these
contacts complete the control circuit to subsequent se-
quencers when more than one is required. These con-
tacts will close after all main contacts have closed and will
open before any of the main contacts open.
FAN INTERLOCK: When multiple sequencers are used,
U.L. requires a fan interlock circuit which will guarantee
that the fan will stay on until all heating elements are de-
energized. The fan interlock circuit must be the first set of
contacts to close and will normally be marked “M1-M2”.
The sequencer may be mounted in any position and
location provided that the temperature does not exceed
the U.L. ambient rating.
Follow the original equipment manufacturers' recom-
mendations for the proper location.
