Johnson Controls FMS-1655 Series Installation Manual page 3

Failure to follow the wiring diagrams could result in damage to your equipment and could void your warranty.
Under no circumstances should a single transformer be split between actuator and controller. Doing so
will damage the actuator, the transformer, the controller or all units. A single 120/24V 30Va transformer
is required for the controller and a separate 120/24V 20Va transformer is required for the actuator. This
equipment contains electrostatic sensitive components. To prevent possible damage, take precautions to
prevent electrostatic discharge when handling or servicing this equipment by wearing an approved ESD
grounding wrist strap connected to an earth ground source.
