SOLID STATE ECONOMIZER SYSTEM
63-2484—2 10
IMPORTANT
Failure to follow these wiring practices can introduce
electrical interference (noise) that can cause erratic
system operation:
a. Keep wiring at least one foot away from large induc-
tive loads such as motors, line starters, lighting bal-
lasts, and large power distribution panels.
b. Shielded cable is required in installations where
these guidelines cannot be met.
c. Ground shield only to grounded controller case.
d. Make good physical wiring connections to ensure
good electrical connections.
e. Make sure that building earth ground connections
are not intermittent or missing.
f. Mount sensor only in recommended environment.

Location and Mounting
LOCATION
Locate the actuator as close as possible to the equipment to
be controlled. Refer to Fig. 12 for mounting dimensions.
Wiring
Disconnect power supply before connecting wiring to prevent
electrical shock or equipment damage. All wiring must comply
with applicable local codes and ordinances.

T6031H THERMOSTAT
Location and Mounting
The T6031H Thermostat mounts either vertically or horizontally
on a wall or panel. Locate the remote bulb as far from the
controller as capillary tubing allows.
Mounting Sensing Elements
T6031H: Install the bulb in the return airflow where air of
average temperature can circulate around it.
IMPORTANT
Do not overtighten clamps to the point of distorting
the sensor bulb because overtightening causes a sig-
nificant shift in bulb calibration.
Mounting Thermostat
Mount the thermostat using the back mounting plate as shown
in Fig. 5.
