INSTALLATION NOTES
A Actuators with appliance cables are numbered.
Provide overload protection and disconnect as required.
Actuators may also be powered by 24 VDC.
Actuators Hot wire must be connected to the control board common. Only connect common to neg. (-) leg of control circuits. Terminal models (-T) have no-feedback.
Actuators may be connected in parallel if not mechanically linked. Power consumption and input impedance must be observed.
Meets cULus requirements without the need of an electrical ground connection.
! 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.
