Wiring multiple...MFT actuators to single shaft and/or on
valves. All MFT actuators are wired in master-slave
configuration.
MFT actuator configurations should also co-ordinate with
each other. Meaning the master input = controllers output.
Master output = slave input. Slave output = controller input.

Equipment damage!
Actuators may be connected in parallel if not mechanically
mounted to the same shaft. Power consumption and input
impedance must be observed.

CAUTION
Indicates a potentially hazardous situation which, if not avoided,
may result in minor or moderate injury. It may also be used to
alert against unsafe practices.

WARNING
Live Electrical Components!
During installation, testing, servicing and troubleshooting of this
product, it may be necessary to work with live electrical
components. Have a qualified licensed electrician or other
individual who has been properly trained in handling live electrical
components perform these tasks. Failure to follow all electrical
safety precautions when exposed to live electrical components
could result in death or serious injury.
Actuators with plenum rated cable do not have numbers on
wires; use color codes instead. Actuators with appliance
cables are numbered.
