WIRING
WARNING: Overriding the imput signal will drive the
actuator to the mechanical end of travel.
WARNING: Do not apply line voltage to terminals
“X”, 2,3,4,7or 8 or the motor will be permanently
damaged.
Inspect unit before installing, look for broken parts or leaks.
Use NEMA TYPE 4 compatible type connectors.
Observe the barrier that separates the line voltage terminals
from the low voltage which operates the actuator motor. All
connections to the line voltage side of the barrier (L1 and L2,
1, 5 and 6 terminals) must be made with Class 1 wiring; con-
nections to the remaining terminals can be Class 2 thermostat
cable if desired.
Allow 6 inches (152mm) clearance above the actuator wiring
compartment.
INSTALLATION
• Disconnect all power to the valves before wiring to
prevent electrical shock and equipment damage.
• Do not exceed the electrical ratings given in the
specifications and on the actuator.
• Attach a flexible 1/2” NPT conduit to the actuator.
• Route the wires through the conduit.
• Use 14 or 16 guage wire for at least 105˚C (221˚F).
• Connect the wiring to the appropriate terminals.
Do not adjust the limit switch beyond 90° unless the standard
slidewire has been replaced with a 180° slidewire; do not adjust
beyond 180° for proportioning control.
In some applications, a Flame Safeguard (FSG) may have
one or two overriding circuits. One being a low fire purge
start and the other a high fire pre-purge. The function of
the violet/white and violet wires are to provide an electrical
connection so that the FSG can override, the temperature
controller and drive the air damper actuator without a 4mA
signal. If such connections are not needed in the application,
simply tape them off, and safely stow away.
