3 NM, 5 NM SERIES SPRING RETURN DIRECT COUPLED ACTUATORS
Humidity Ratings:
 5% to 95% R.H., Non-Condensing

Electrical Connections:

 Field wiring 18 AWG (0.5 mm) to 14 AWG (1.5 mm)
conductors (stranded or solid) and up to 2 - 14 AWG (1.5
mm) conductors (stranded) to screw terminals, located
under the removable access cover.
Auxiliary Switch (One SPDT):
 Switch adjustable from 0-95°
 500 uA Resistive at 5 Vdc (minimum)
 250 Vac, 8 A resistive, 3 A inductive
Mounting: Self-centering shaft adapter (shaft coupling):
 Round damper shafts: 3/8 to 5/8 in. (9 to 16 mm)
 Square damper shafts: 1/4 to 1/2 in. (6 to 13 mm)
Minimum Damper Shaft Length:
 1 in. (25 mm); 3 in.(76 mm) recommended.
Spring Return Timing (at rated load):
 < 25 seconds @ -4°F to 130°F (-20°C to 55°C)
< 60 seconds @ -22°F (-30°C)

Cable Specification:

 300 V, 75° C, Plenum Rated, 3 ft length from end of access
cover, 18 AWG
Sylk™ Bus:
 Sylk is a two-wire, polarity insensitive bus that provides
communications between a Sylk-enabled actuator and a
Sylk-enabled controller. For wiring, the Sylk-enabled
actuator may be mounted up to 200 ft. (61 m) from the
controller; twisted pair wire is recommended for wire runs
longer than 100 ft. (30.5 m). Using Sylk-enabled actuators
saves I/O on the controller and is faster and cheaper to
install since the bus is polarity insensitive.
