MODEL BGUS/BGUS-D • SG/SG-D OPERATOR INSTALLATION GUIDE

WIRING SPECIFICATIONS

1.Select from the chart at the bottom of this page corresponding 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 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 connection.

4.All control devices are now 24VDC, which can be run considerable distances. 24VAC is available for other devices, such as loop detectors and photo eyes.

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 requirements.

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 consumption devices only. If you choose to run dedicated equipment 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 connect master and slave operators. You must use Belden 8760 Twisted Pair Shielded Cable (or equivalent) only – LINEAR 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.
