UL 6200

Outline of Investigation for Controls For Stationary Engine Driven Assemblies

1.1 These requirements apply to control panels, control units, and other various electrical circuits employed within a control circuit device for use in a Stationary Engine Driven Assembly or similar equipment applications.

1.2 These requirements cover controls operating at 600 Volts maximum with sensing and measurement circuits of 1000 Volts AC and 1500 Volts DC maximum.

1.3 These requirements apply only to electrically operated control equipment.

1.4 These requirements apply to equipment intended to be operated and installed by skilled personnel in the field.

1.5 These requirements do not apply to devices in the power circuit, but may apply to pilot devices that would control switching devices in the power circuit and devices that include circuits that monitor a power circuit.

1.6 These requirements do not apply to controls for the propulsion engine of a vehicle.

1.7 These requirements apply to control equipment used in or with Movable engine driven assemblies that are otherwise constructed the same as Stationary engine driven assemblies.

1.8 These requirements do not apply to independent equipment that does not perform any control function of an engine driven assembly.

1.9 These requirements may supplement but do not cover equipment or devices for use in or connected to hazardous (Classified) locations.
