** Due to the nature of motor requirements, secondary circuits, and controls,
208V operators are severely limited in run distance. Exceeding these rec-
ommended distances could lead to frequent maintenance and motor failure.

1. Select from the chart at the bottom of this page corre-
sponding to the model, voltage and horsepower rating of
your operator.
2. The distance shown on the chart is measured in feet from
the operator to the power source. DO NOT EXCEED THE
MAXIMUM DISTANCE. These calculations have been
based on standard 115V and 230V supplies with a 10%
drop allowable. If your supply is under the standard rating,
the runs listed may be longer than what your application
will handle, and you should not run wire too near the up-
per end of the chart for the gauge of wire you are using.
3. When large-gauge wire is used, a separate junction box
(not supplied) may be needed for the operator power con-
nection.
4. All control devices are now 24VDC, which can be run con-
siderable distances.
5. Wire run calculations are based on the National Electrical
Code, Article 430 and have been carefully determined
based on motor inrush, brake solenoids, and operator re-
quirements.
WIRING SPECIFICATIONS
6. Connect power in accordance with local codes. The green
ground wire must be properly connected.
7. Wire insulation must be suitable to the application.
8. Control wiring must be run in a separate conduit from power
wiring. Running them together may cause interference and
faulty signals in some accessories.
9. Electrical outlets are supplied in all 115VAC models for
convenience with occasional use or low power consump-
tion devices only. If you choose to run dedicated equip-
ment from these devices, it will decrease the distance for
maximum run and the charts will no longer be accurate.
10. A three-wire shielded conductor cable is required to con-
nect master and slave operators. You must use Belden
8760 Twisted Pair Shielded Cable (or equivalent) only –
OSCO part number 2500-1982, per foot). See page 10 for
details of this connection, as well as dip switch selection.
Note: The SHIELD wire should be connected in both
the master and slave operators.
