Liftmaster 02703 NEMA 7/9 3-Button Control Station Explosion Proof Surface Mount
The LiftMaster 02703 is a heavy-duty three-button control station built for commercial and industrial operator control in hazardous area environments. It gives the user separate OPEN, CLOSE, and STOP buttons from a surface-mounted station, allowing basic operator control without using a remote, keypad, or wall console. This style of station is used where the job requires a rugged enclosure and a control device rated for more demanding locations than a typical indoor push button station.
This product is commonly referenced as a NEMA 7/9 hazardous area or explosion proof control station. Catalog descriptions associate the enclosure with NEC Class I, Divisions I and II, Group D, and Class II, Divisions I and II, Groups F and G. Those ratings are application-dependent and must be handled correctly in the field; the control station alone does not make the entire installation code compliant.
The 02703 is a control station, not a motor starter, logic board, receiver, or safety device. It is typically connected into the low-voltage or control circuit of a compatible commercial/industrial operator. Because hazardous-location wiring and conduit requirements are specialized, this is not a casual replacement item for residential garage doors or general outdoor controls.

Common Compatible Applications
This control station may be used with compatible LiftMaster industrial operator control circuits when the wiring and site rating are appropriate. Typical applications include:
- LiftMaster industrial door operators that accept external OPEN/CLOSE/STOP station control
- Commercial overhead door operators requiring a three-button station
- Hazardous area control locations requiring a NEMA 7/9 style station
- Industrial facilities where the control station is specified by the job engineer or operator manual
Important Compatibility Notes
- Confirm operator control voltage and terminal layout before ordering.
- This is not a universal residential wall button or Security+ wall control.
- Hazardous location installations must meet electrical code, enclosure, fitting, seal-off, and conduit requirements.
- Do not use this station as a substitute for required monitored safety devices or entrapment protection.

Technician Note
The control station must match the operator control circuit and the site classification. A standard push button station should not be substituted where the job requires a hazardous-location enclosure.
Before Ordering Checklist
- Confirm the operator accepts OPEN/CLOSE/STOP external station wiring.
- Verify control voltage and terminal designations.
- Confirm the hazardous area classification for the installation location.
- Review conduit, fitting, and seal-off requirements with a qualified electrician.
- Confirm required safety devices remain installed and functional.
Professional Advisory
Hazardous-location electrical work should be performed by a qualified electrician or industrial door technician. Do not bypass monitored safety devices or modify operator control circuits outside the manufacturer instructions.
