2-7 Terminal connections
Use minimum 75°C copper wire only.
Minimum wire size must conform to 75°C table per electrical codes.
Tighten connections with following torque:
• QS2B-QS2I, wire range #14-#8 AWG, torque 20 in lb.
Output Relay
Run mode: Contact 11-14 closes when the run order is given to start the unit. Contact 11-14 opens if
either the stop order is given or an error is found, and the unit turns off. If soft stop is programmed,
contact opens when the soft stop ramp is complete.
End-of-ramp (at speed) mode: Contact 11-14 closes when the starting ramp voltage reaches the
end of ramp (i.e., full voltage). Contact 11-14 opens if either the stop order is given or an error is
found, and the unit turns off. If soft stop is programmed, contact opens prior to the beginning of soft
stop ramp.

Note: When ASTAT-SD reduced voltage starters are used in conjunction with semi-conductor fuses,
Type 2 Coordination to IEC 947-4 is attained. These fuses are recommended for best overall
short-circuit protection. The semi-conductor fuse specified may provide branch circuit protection.
Refer to local applicable electrical codes.
1Suitable for use on a circuit capable of delivering not more than 100KA rms symmetrical amperes, for 208V, 240V and up
to 480V maximum, when used with the semi-conductor fuse for short-circuit protection. Listed with Gould Shawmut Form
101, Type A50QS.
2Suitable for use on a circuit capable of delivering not more than 25KA rms symmetrical amperes, for 208V, 240V and
up to 480V maximum, when used with Class RK5 and J fuse.
3Suitable for use on a circuit capable of delivering not more than 25KA rms symmetrical amperes, for 208V, 240V and
up to 480V maximum, when used with circuit breakers.
