WARNING
Disconnect power before installation to prevent
electrical shock or equipment damage.
Disconnect external power before wiring to prevent elec-
trical shock or equipment damage. All wiring must comply
with applicable codes and ordinances.
IMPORTANT: The T775 is an operating control, not a
limit or safety control. If used in applications requir-
ing safety or limit controls, use a separate safety or
limit control device in conjunction with the T775.
WARNING
Do not use 24 Vac power at terminals 5 and 6 to
power any external loads if 120 Vac or 240 Vac is
used to power the T775.
Refer to Fig. 3 or 4 for locating the appropriate power
inputs, remote sensor input, load output terminals, contact
closure input and sensor selection switch. Access to the
terminals can be gained through standard conduit knockouts
(A through C) located around the perimeter of the enclosure.
NOTE: Hole A should only be used for sensor, low-voltage
and contact closure wiring.
