WIRING SPECIFICATIONS

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 power supplies with a 10% allowable voltage drop. If the available voltage is less than the stan- dard rating, the wire lengths listed may be longer than what your application will handle. If this is the case, you should not allow your wire length to reach the upper 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 wired considerable distances.

5.Wire length calculations are based on the National Elec- trical Code, Article 430 and have been carefully deter- mined based on motor inrush, brake solenoids, and op- erator requirements.

6.Connect power in accordance with local codes. All power wiring should be done by a licensed electrician. 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 power dedicated equip- ment from these devices, it will decrease the distance for maximum wire length 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 9 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.
