CONNECTIONS
Before starting any electrical connection:
• Make sure the cable being used has the correct voltage and
current rating for the application.
• Do NOT exceed the stated drive voltage for the AD1240 on
any of the input pins (24VAC).
• If installing an AD1240 model with presets, make sure the
potentiometer wiper is not connected to the supply voltage.
• If the model has either the AutoPan or Heater feature, make
sure the drive voltage supplied at the input pins for either
model is 24VAC ±10%.
• All control voltages to the AD1240 must be wired to the
connector. A mating connector is supplied, according to the
model (AD1240 or AD1240P, see contents list, page 2).
Typical connections of the AD1240 Series Pan/Tilt to AD1641
Series Receiver/Drivers are illustrated in the Typical System
Connection section at the end of this manual.
Note: Following electrical connections to the AD1240
AutoPan models (AD1240/24A or AD1240/24PA), the
unit must be set for the proper AutoPan ends stops.
See Setup, page 12, for setting the end stops for
AutoPan operation.
Wire Selection
The following table shows wire gauge versus the maximum
distance between the pan/tilt and the voltage controlling source
(e.g., Receiver/Driver). For the AD1240 models with presets,
shielded cable is recommended for most applications.

Note: Distances calculations are based on solid copper wire,
single common, and worst case current draw (i.e.,
diagonal pan/tilt operation).
Wiring
The connection wiring for the AD1240 depends on the model.
• The models without Preset capability (AD1240/24,
AD1240/24A, and AD1240/24H) are connected using a 7-
pin connector. A mating 7-pin connector assembly is
provided. See page 7 for wiring this connector.
• The models with Preset capability (AD1240/24P,
AD1240/24PA, and AD1240/24PH) are connected using a
13-pin connector. A mating 13-pin connector assembly is
provided. See page 8 for wiring this connector.
Following the connector wiring, attach the cable to the
AD1240 chassis using the cable strain relief assembly on the
bottom of the main body. See page 10 for attaching the cable
to the strain relief assembly.
