Installation Procedures

• screwdriver, Phillips-head (No. 1 or 2)
• screwdriver, flat-blade, 1/8 inch tip
Note: All series M100 motor actuators are for use only as operating controls.
Where an operating control failure would result in personal injury
and/or loss of property, it is the responsibility of the user to add
devices (safety, limit controls) or systems (alarm, supervisory systems)
that protect against and/or warn of control failure.
•
Follow NEC and local electrical codes.
•
Disconnect all power supplies.
•
Observe the following ranges and limitations:

Ambient Storage
Conditions
•
Do not install the motor actuator in atmospheres with explosive vapors
or escaping gases, or where vapors having deteriorating properties
might attack the actuator's metal parts.
•
Wiring into return air systems should be sealed to prevent aspiration of
corrosive air into the actuator.
Upright mounting of the motor actuator is required.
When mounting on a valve, do not mount below the horizontal plane of
the valve piping to prevent damage to the motor actuator if the valve leaks
or develops condensation.
Valve medium temperatures above 250°F (121°C) are permissible only if
the maximum ambient temperature at the motor actuator is less than
105°F (41°C).
Locate the motor actuator where the shaft and wiring terminals are accessible.
Follow installation procedures for the linkage kit used to couple the motor
actuator and the controlled device.
When not utilizing a damper or valve linkage kit, use four 1/4 x 1 inch
bolts for mounting the motor actuator.
Perform travel adjustments described in the Travel Adjustment section as required.
